The user is having an issue where a float division in a MIPS/MIPSel Linux binary runs correctly in full emulation but gives the wrong result in QEMU user mode. The problem is specifically with the division resulting in 2.0 instead of 0.5 when using QEMU user mode. + +First, I need to recall what QEMU user mode does. It allows running binaries from another architecture on the host system without emulating the whole OS. So, for example, running a MIPS binary on an x86 host. The user mentioned that when they run the same binary in a fully emulated Debian environment (using QEMU system mode), it works correctly. But when using QEMU user mode, it's broken. + +The key here is that the issue is related to floating-point division. The code is straightforward: dividing an integer by a double. The problem is that the result is wrong in user mode. Since the same binary works when run natively or in full emulation, the problem is specific to QEMU's user mode emulation. + +Now, thinking about possible causes. Floating-point operations can be tricky. QEMU user mode needs to correctly emulate the CPU's floating-point unit (FPU). If the FPU emulation is incorrect, especially for division, that could lead to such errors. This would fall under the "instruction" category because it's about the correct execution of CPU instructions. The division instruction for floating-point might not be handled properly in QEMU's user mode for MIPS. + +Another angle: syscalls. But in this code, the main operation is a floating-point calculation, not a system call. The printf is a standard function that uses syscalls, but the division itself is part of the program's logic, not a syscall. So the issue isn't with a specific system call but with how the instruction (specifically, the floating-point division instruction) is executed by QEMU in user mode. + +Runtime errors could be things like dynamic linking issues or library problems, but the user tested the same binary in different environments. The cross-compiled binary works in full emulation and natively, so the problem isn't with the runtime libraries but with the emulation of the CPU instructions in user mode. + +Therefore, the problem is likely due to a faulty emulation of the floating-point division instruction in QEMU's user mode for MIPS.

For example, if the instruction encoding is such that the MOVQ and MOVL have different lengths, then after executing the first instruction, the next instruction's address might be miscalculated.

But in the problem statement, the next instruction is at 0x2206, which suggests that the first instruction is 4 bytes long. Wait, the first instruction is "mov -0x8(%rbp),%rax". Let me check the x86 instruction encoding. The MOV instruction from memory to RAX would be something like 48 8b 85 ... (for a 64-bit operand size). The displacement is 0x8, so the instruction length would be 1 (opcode) + modr/m (1 byte) + displacement (4 bytes?), maybe. So maybe the instruction is 6 bytes long. For example, 0x48 0x8b 0x85 (opcode and modr/m) followed by 0xf8 ff ff ff (for -0x8 displacement). So that's 6 bytes. If the first instruction is at 0x2202, then the next instruction would be at 0x2208. But in the problem description, the next instruction is at 0x2206. That suggests that the disassembly might be incorrect. If the initial disassembly is wrong, perhaps the PC is not advanced correctly, leading to the next instruction being misaligned, which could cause the instruction to be misdecoded. For example, if the first instruction is actually shorter than expected, then the PC would point to the middle of the next instruction. Then, when trying to execute the next instruction, it's being read as a different instruction. + +In the problem statement, after executing the first instruction (which is at 0x2202), the next instruction is at 0x2206. Then, when looking at the instruction at $pc (0x2206), it's a "movq $0xb8000, (%rax)". But after execution, when looking again, the instruction is at 0x2207 and is a "movl". This suggests that the instruction pointer (PC) advanced by only 1 byte. That would happen if the instruction at 0x2206 is 1 byte long. But why would that instruction be 1 byte? The instruction "movq $0xb8000, (%rax)" is a MOV instruction with a 64-bit immediate to memory. The encoding for that would be 48 (REX.W for 64-bit operand), 89 (MOV), but wait, no. Wait, the instruction is moving an immediate value to memory. So the correct instruction is "movabs", which in x86 is encoded with a 32-bit immediate, but for 64-bit, it's a 48-bit immediate? Wait, no. The x86 instruction set doesn't have a "movq" mnemonic in the sense of moving a 64-bit immediate. The correct instruction to move a 64-bit immediate into a register is "movabs", but when moving to memory, it's a bit different. Wait, actually, the instruction "movq $0xb8000, (%rax)" would be encoded as a MOV instruction with a 32-bit immediate, but sign-extended to 64 bits. Wait, but $0xb8000 is a 20-bit address. However, in x86-64, when you use an immediate with a MOV to memory, the immediate is 32 bits (for movl) or 64 bits (for movabs). But in the case of "movq $0xb8000, (%rax)", I think that's not a valid instruction. The "movq" mnemonic is typically used for moving data between registers or memory, but when using an immediate, it's usually "mov $imm, ...". The "q" suffix just indicates the operand size. So the instruction "mov $0xb8000, (%rax)" would be a 64-bit MOV, which is encoded with a 32-bit immediate (sign-extended to 64 bits). So the encoding would be something like 48 c7 00 00 b8 00 00. That's 7 bytes. So if the instruction at 0x2206 is 7 bytes long, then after executing it, the PC would be at 0x2206 + 7 = 0x220d. But the user says that after executing the instruction at 0x2206, the next instruction is at 0x2207. That suggests that the instruction length was miscalculated. If the emulator (QEMU) is not correctly calculating the instruction length, then the PC would be pointing to the wrong address, leading to the next instruction being misdecoded. + +In the problem description, after executing the instruction at 0x2206, the next instruction is at 0x2207. The user then looks at the instruction at $pc (0x2207) and sees "movl $0xb8000, (%rax)". But the original instruction was supposed to be "movq". So this suggests that the PC advanced by only 1 byte, leading to the next instruction being read as a different instruction. This would be a problem in the instruction decoding or execution in QEMU. The instruction length is not being correctly calculated, causing the PC to be wrong. Therefore, when the next instruction is fetched, it's being interpreted as a different instruction (movl instead of movq), which could lead to incorrect execution. + +This seems like an issue with how QEMU is handling the instruction decoding or execution, leading to the wrong instruction being executed and possibly altering the RAX register in an unexpected way. The user's problem is that RAX ends up being 0x7fefe instead of 0x7fedf. However, the RAX value is modified after the instruction that's supposed to write to memory. The instruction "movq $0xb8000, (%rax)" would write the value 0xb8000 to the memory address in RAX. But according to the user, after executing this instruction, RAX changes to 0x7fefe. But that doesn't make sense unless the instruction is actually modifying RAX. However, the instruction "movq $0xb8000, (%rax)" should not modify RAX. So why is RAX changing? + +Wait, perhaps the user made a mistake in the problem description. Let me check again. The user says that after executing the first instruction (mov -0x8(%rbp), %rax), RAX is 0x7fedf. Then, executing the next instruction (movq $0xb8000, (%rax)) should write to memory at address 0x7fedf. But after that, the user says RAX becomes 0x7fefe, which is 1 less. However, the instruction shouldn't change RAX. Unless there's a mistake in the instruction encoding. For example, if the instruction is actually a different instruction that does modify RAX. But how? + +Alternatively, perhaps the instruction pointer is wrong, leading to the next instruction being executed incorrectly. For example, if the first instruction is longer than expected, and the PC is advanced by the wrong amount. Then, when the next instruction is executed, it's a different instruction that does modify RAX. + +In the problem description, after executing the first instruction (0x2202), the next instruction is at 0x2206. The instruction is "movq $0xb8000, (%rax)". Let's assume that this instruction is 7 bytes long. So after executing it, the PC should be at 0x2206 + 7 = 0x220d. But the user says that after executing it, the next instruction is at 0x2207. That suggests that the PC was advanced by only 1 byte. So the instruction at 0x2206 was only 1 byte long. But that's impossible for a "movq" instruction. So this implies that QEMU's instruction decoder is not correctly calculating the instruction length. As a result, the PC is pointing to 0x2206 + 1 = 0x2207, and the next instruction is being decoded as "movl $0xb8000, (%rax)". + +But why would this happen? If the instruction at 0x2206 is not correctly decoded, perhaps because the decoder in QEMU is not handling the instruction correctly. For example, perhaps it's decoding a different instruction that is only 1 byte long, leading to the PC being advanced incorrectly. Then, when the next instruction is executed, which is actually part of the original instruction's encoding, it's misinterpreted as a different instruction. + +In this case, the problem is that the instruction decoding is incorrect, leading to the wrong instruction being executed. The result is that the RAX register is modified in an unexpected way. Therefore, this is a bug related to the instruction execution in QEMU. + +The user's problem is caused by QEMU incorrectly decoding the instruction length, leading to incorrect instructions being executed.

The user is reporting that when they run a program under qemu-ppc, there's a discrepancy in the output of a float32 conversion compared to running it natively on a PPC64 system. The example code takes a uint32_t value, reinterprets it as a float, and prints it. The native output is 1.401298e-45, but under QEMU, it's 2.802597e-45, which is exactly double. + +First, I need to understand why this discrepancy occurs. The key here is how the float is being interpreted. The value 0x1 as a 32-bit float is a very small number. The correct value for 0x31 in hex (which is 1 in decimal) as a float would depend on the endianness and the actual bit pattern. Wait, wait, the code is taking the uint32_t i = 1, which is 0x00000001 in 32 bits. When reinterpreted as a float, that bit pattern represents a float. Let's think about the IEEE 754 format. + +For a 32-bit float, the first bit is the sign bit (0 here), the next 8 bits are the exponent, and the remaining 23 are the mantissa. The value 0x00000001 in hex is 0 00000000 00000000000000000000001. The exponent is all zeros, and the mantissa has a single 1 bit. That's a subnormal number. The value would be 1 * 2^(-126) multiplied by 2^(-23) (since the mantissa is 1 * 2^-23), but wait, maybe I'm getting that wrong. Let me calculate. The actual value is (0 + 1 * 2^-23) * 2^(-126 + 127 - 127?), no, wait. For subnormal numbers, the exponent is -126 (since the exponent bias is 127, and all exponent bits are zero, so actual exponent is -126). The mantissa is 0.mantissa_bits, so here it's 1/(2^23). So the value is 1/(2^23) * 2^-126 = 1/(2^149). Let me compute that. 2^10 is 1024, 2^20 is ~1e6, 2^30 ~1e9, so 2^149 is 2^(140 + 9) = (2^10)^14 * 512. Let's approximate 2^149 ≈ 1.7e44. So 1/2^149 ≈ 5.7e-45. Wait, but the user's outputs are around 1.4e-45 and 2.8e-45. Hmm. Maybe my calculation is off. Alternatively, perhaps there's an endianness issue. + +Wait, the code is taking a uint32_t (which is in host endianness) and reinterpreting it as a float. But on a big-endian system (like PPC), the byte order might differ. However, the user is using qemu-ppc, which emulates a PowerPC (big-endian) environment. But when they run the code natively on a PPC64 system (which is big-endian), the output is 1.4e-45. Under QEMU, the output is double that. + +Wait, the two outputs differ by a factor of two. 1.4e-45 multiplied by two is 2.8e-45. So what could cause that? Let me think about the bit pattern. If the uint32_t is 1, stored as 0x00000001 in memory. On a big-endian system, when you cast that to a float, the bytes are 0x00 0x00 0x00 0x01. But on a little-endian system, the same uint32_t would be stored as 0x01 0x00 0x00 0x00, which would be a different float value. However, the user is using qemu-ppc, which should emulate big-endian behavior. But maybe there's a mistake in how QEMU handles the float conversion, perhaps due to incorrect endianness handling when translating the integer to float? Or maybe the float is being reinterpreted with the wrong endianness. + +Alternatively, perhaps the problem is that the code is using a volatile uint32_t and then reinterpreting it as a float. The cast via (float*)&i could be causing undefined behavior, but the user is using -fno-strict-aliasing, which should allow that. But the real issue is how the bits are interpreted. If QEMU's translation of the float is incorrect, perhaps because the emulator's FPU is not handling the conversion correctly. For example, maybe the emulator is using the host's FPU (which is likely x86, which is little-endian) and mishandling the endianness when converting the integer to float. + +Wait, when the code does *(float*)&i, it's taking the 4 bytes of the integer i and reinterpreting them as a float. So if i is 1, stored as a 32-bit integer in memory. On a big-endian system, the bytes are 00 00 00 01. On a little-endian system, they are 01 00 00 00. When those bytes are interpreted as a float, the value would be different. The native PPC output is 1.4e-45, which would correspond to the big-endian byte order. The QEMU output is 2.8e-45, which is exactly double. Let's see what the actual bit pattern would be. If the bytes were 00 00 00 01 (big-endian), that's the same as the 32-bit integer 1. But if QEMU is somehow interpreting it as little-endian, the bit pattern would be 01 00 00 00, which is 0x01000000. Let's see what that represents as a float. The sign bit is 0, exponent is 0x01 (which is 1 in hex, but as part of the exponent field). Wait, the exponent is 8 bits. If the first byte is 0x01, then the exponent bits are 0x01 (assuming big-endian). Wait, no, if the float is stored in big-endian, the first byte is the sign and exponent. But if the bytes are 0x01 followed by zeros (as in little-endian), then the exponent would be 0x01, which is 1. The actual exponent is 1 - 127 = -126. The mantissa is all zeros. So the value would be 1.0 * 2^-126. Let's compute that. 2^-126 is approximately 1.5e-38. But that's not matching the numbers given. Hmm, maybe I'm getting confused here. + +Alternatively, maybe the issue is that QEMU is not correctly emulating the PowerPC's floating-point unit. For example, when the code reinterprets the integer as a float, the PowerPC would do that by taking the 32 bits as the float's bits (since it's big-endian). But if QEMU is translating the code to x86, which is little-endian, perhaps there's a mistake in how the bits are handled. For example, if QEMU is not adjusting the endianness when converting between integer and float, leading to the bits being in the wrong order. Let's take the example: the uint32_t is 1, stored as 0x00000001 (big-endian). When cast to a float, that's the same as the 32-bit float with the bit pattern 00000000 00000000 00000000 00000001. That's a subnormal number, as discussed earlier. However, if QEMU is interpreting the integer as little-endian when converting to float, the bit pattern would be 0x01000000, which would be a different float. Let's calculate that. The bit pattern would be sign bit 0, exponent 0x01 (so 1 - 127 = -126), and mantissa 0x000000. That would be 1.0 * 2^-126 ≈ 1.5e-38. But the user's QEMU output is 2.8e-45, which is much smaller. So that's not matching. + +Wait, maybe there's a mistake in the way QEMU handles the float conversion. For example, if the code is using a cast to reinterpret the bits, but QEMU's translation is not handling the endianness correctly. Alternatively, perhaps the problem is that the host system (x86) uses IEEE floats, but QEMU is not correctly handling the PowerPC float format. But PowerPC uses the same IEEE 754 format for 32-bit floats as x86, right? So the bit pattern should be the same. Therefore, the problem is not the float format but the way the bits are being interpreted. + +Wait, perhaps the problem is that when the code does *(float*)&i, the PowerPC would take the 4 bytes as a big-endian float, but QEMU is handling it as little-endian. For example, if the code is generating a load of the 32-bit integer into a float register, but on PowerPC, the load is done in big-endian, whereas QEMU is emulating it as little-endian. So the same 4 bytes (00 00 00 01) would be interpreted as the float 0x01000000 in little-endian, which would be a different value. Let's calculate that. The bit pattern in little-endian would be 01 00 00 00 in memory, which as a 32-bit value is 0x01000000. The sign bit is 0, exponent is 0x01 (which is 1 in the exponent field), and the mantissa is 0x000000. So the value is 1.0 * 2^(1 - 127) = 2^-126 ≈ 1.5e-38. But the QEMU output is 2.8e-45, which is 2^-147. How does that happen? Wait, maybe the actual bit pattern is different. Let me think again. + +If the integer is 1, stored in memory as 00 00 00 01 (big-endian), then when you cast that to a float, the float's bits are 0x00000001. The exponent is all zeros (so subnormal), and the mantissa is 1. The value is (0 + 1 * 2^-23) * 2^-126 = 1/(2^23 * 2^126) = 1/(2^149) ≈ 1.4e-45. Which matches the native PPC output. However, if QEMU is interpreting the same bytes as little-endian, then the float's bit pattern would be 0x01000000. The exponent is 0x01 (binary 00000001), which is 1. The exponent bias is 127, so actual exponent is 1 - 127 = -126. The mantissa is 0. So the value is 1.0 * 2^-126 ≈ 1.5e-38. But the QEMU output is 2.8e-45, which is 2.8e-45 ≈ 1/(2^147). So that's not matching either. Hmm. + +Wait, perhaps there's another factor. Maybe the problem is not endianness but the actual conversion between integer and float. For example, when you cast an integer to a float, the C standard says that the integer is converted to the floating-point type. But in this case, the code uses a cast via a pointer, which is undefined behavior unless you use -fno-strict-aliasing and the types are compatible. However, the user is using -fno-strict-aliasing. But perhaps the real issue is that the code is relying on the representation of the integer as a float, which depends on the endianness. + +But the user's test case is designed to check how the bits are reinterpreted.

So in this case, the instruction is cmpxchg edi, mem. Which means, compare the value in RAX (the implicit first operand) with the memory. If they are equal, then the memory is replaced with EDI's value. Otherwise, RAX is updated with the memory's value. + +But the operand size here is 32 bits. So when using cmpxchg with a 32-bit operand size, RAX's lower 32 bits (EAX) is compared with the memory. The initial RAX is 0x1234567812345678. So EAX is 0x12345678. The memory is 0x12345678.

Maybe there's a bug in the QEMU emulator's implementation of the SLL instruction where it's not correctly masking the shift amount to 5 bits, or perhaps there's an error in how the registers are being accessed. For example, if the code was accidentally using a 32-bit register instead of a 64-bit one, then shifting by 4 in a 32-bit context and then extending might lead to the observed result. + +Looking at the C code: the variables are uint64_t, and the asm is using "r" constraints, which should select 64-bit registers. But if QEMU's RISC-V emulation has a bug where it's treating the registers as 32-bit (like using the wrong register size), then shifting a 32-bit value and then zero-extending would result in the lower 32 bits being shifted and upper bits zero. For example, if the emulator was using 32-bit registers, then shifting 0xDB4D6868655C3585 (which is 0xDB4D...3585 as a 64-bit value) as a 32-bit value would only take the lower 32 bits (0x655C3585), shift by 4 to get 0x655C3585 * 16 = 0x55C35850, then zero-extend to 64 bits, giving 0x0000000055C35850. But the observed output is 0x55c3585000000000, which is that 32-bit result shifted left by 32 bits.

But if there's an overflow in the address calculation, maybe. For example, if the address calculation for -48(s0) is done incorrectly. Let's check: s0 is 0x80000000, subtract 48 (0x30) gives 0x80000000 - 0x30 = 0x7fffffd0. That's correct. So the address is valid. + +But maybe QEMU is not handling sign extension correctly when loading the word. For example, if the memory at that address contains 0x00000000, then loading with lw would result in 0x00000000. If it's 0xffffffff, then sign-extended to 64 bits would be 0xffffffffffffffff. But the user's result is 0xffffffff, which is 32 bits. That suggests that perhaps the register is being written with a 32-bit value instead of 64, which would be a problem in the instruction's handling.

The user says there's a problem with the BEXTR instruction in QEMU. The issue is that the result in the destination register (RAX) is different between the actual CPU and QEMU. The example given shows that on the CPU, RAX ends up as 0x5a, but in QEMU it's 0x635a775a. + +The user also mentions that they think QEMU isn't considering the operand size limit. BEXTR is an x86 instruction that extracts bits from a source operand based on a bit mask provided in another operand. The operands here are 64-bit registers (RBX and RCX), but the destination is EAX, which is 32 bits. + +Wait, the instruction in the code is "bextr eax, ebx, ecx". So the destination is 32-bit (EAX), and the sources are EBX and ECX (32-bit), but in the code, they're setting RBX and RCX to 64-bit values. But in 64-bit mode, using 32-bit registers would zero-extend them? Or does the BEXTR instruction handle the operand sizes correctly? + +The problem here is that QEMU might not be handling the operand size correctly. The BEXTR instruction's behavior depends on the operand size. For example, if the instruction is 32-bit (like using EAX, EBX, ECX), the operation should be on 32 bits. But if the sources are 64-bit registers (RBX, RCX) but the instruction is using their lower 32 bits (EBX, ECX), maybe there's a difference in how the CPU and QEMU handle the upper bits. However, in x86-64 mode, when you use 32-bit registers, the upper 32 bits of the 64-bit register are cleared. So when you move a 64-bit value into RBX, then use EBX as a 32-bit operand, the upper 32 bits of RBX are preserved, but EBX is just the lower 32 bits. However, when you use EBX in an instruction, the upper 32 bits of RBX aren't part of the operation. + +But the problem here is that the BEXTR instruction's sources are EBX and ECX (32-bit) even though their 64-bit counterparts (RBX, RCX) are set to larger values. The CPU would use the lower 32 bits of EBX and ECX for the BEXTR operation, but QEMU might be using the full 64-bit values instead. Wait, no. Because when you use the 32-bit versions, the instruction's operand size is 32 bits. So BEXTR would operate on 32-bit sources. The first source is EBX, which is 0x8f635a775ad3b9b4's lower 32 bits. Let's compute that. The value of RBX is 0x8f635a775ad3b9b4. The lower 32 bits (EBX) would be 0x5ad3b9b4. Similarly, ECX is lower 32 bits of RCX (0xb717b75da9983018) which is 0xa9983018. Then the BEXTR instruction uses EBX and ECX as 32-bit operands. The BEXTR instruction's operation is to extract 'width' bits starting from 'index' from the source. So the ECX here holds the index and width? Wait, BEXTR has two sources: the first source is the data, the second source is the index and width. So BEXTR r/m64, r64, r64 — but in this case, the instruction is using the 32-bit versions. + +Wait, the BEXTR instruction's encoding. The instruction format is BEXTR dest, src, index. The index is in the third operand, which provides the starting bit and the width. But for the BEXTR instruction, the operand size determines how many bits are considered. For example, if operand size is 32 bits, then the index and width are in bits, and the source is treated as 32 bits. So if QEMU is not considering the operand size correctly, perhaps when the instruction is using 32-bit operand size (like EAX, EBX, ECX), it's using the full 64-bit values of RBX and RCX instead of their lower 32 bits. + +In the example, the user's code uses "mov rbx, 0x8f635a775ad3b9b4" which sets RBX to a 64-bit value. Then, in the BEXTR instruction, they use EBX (the lower 32 bits of RBX). So the EBX value is 0x5ad3b9b4. Similarly, ECX is 0xa9983018. + +The BEXTR instruction's second operand is the index and width. The ECX here would be split into the index (lower 16 bits) and width (upper 16 bits). Let's see: ECX is 0xa9983018. Lower 16 bits are 0x3018 (index), upper 16 bits are 0xa998 (width). But wait, in BEXTR, the index and width are stored in the same register. The instruction uses the lower 16 bits for the index and the upper 16 bits for the width. So for a 32-bit operand size, the index and width are each 16 bits. + +So the calculation would be: extract 'width' bits starting from 'index' in the source. But if the source is 32 bits (EBX is 0x5ad3b9b4), then the bits are from 0 to 31. The index is 0x3018 (which is 12312 in decimal), but that's way beyond 32 bits. So the CPU would handle it as per the BEXTR instruction's semantics. According to Intel's documentation, if the index or width is out of range, the result is undefined or zeroed. However, in practice, the BEXTR instruction may return zero if the index is beyond the operand size. + +But the user says that the CPU gives RAX = 0x5a. Let's see. Let's try to compute what BEXTR eax, ebx, ecx would do. + +EBX is 0x5ad3b9b4 (32 bits). ECX is 0xa9983018. The index is 0x3018 (12312) and width is 0xa998 (43416). But since the operand size is 32 bits (so 32 bits in EBX), the index is 12312, which is larger than 31. Therefore, the result should be zero, but maybe there's some other handling. Wait, perhaps the CPU clamps the index and width to the operand size. For example, if the index is larger than the operand size, it returns zero. + +But the user's CPU result is 0x5a. How can that be? Let's think. Maybe the actual index and width are different. Wait, perhaps I made a mistake in splitting ECX. Let me check again. The ECX value is 0xa9983018. In BEXTR, the lower 16 bits are the index, upper 16 bits are the width. So index is 0x3018 (12312), width is 0xa998 (43416). But for a 32-bit operand, the maximum index would be 31 (since there are 32 bits). So index is way beyond that. So the result should be zero. But the user says the CPU result is 0x5a. That suggests that perhaps the actual index and width are different. Maybe I'm misunderstanding how ECX is split. + +Wait, perhaps the BEXTR instruction uses the lower 8 bits for index and upper 8 bits for width? No, that's not correct. The BEXTR instruction uses the lower 16 bits as the index and upper 16 as the width, regardless of operand size. For example, in 64-bit operand size, the index and width are each 16 bits. + +Wait, but if the operand size is 32 bits, then the source is 32 bits. The index can be up to 31, and the width can be up to 32. So if the index is beyond 31, the result is undefined. But in the example, the index is 0x3018 (12312), which is way beyond 31. So why does the CPU return 0x5a? That seems odd. + +Wait, maybe there's a mistake in the way I'm interpreting the ECX value. Let me look at the code again. The code says: + +mov rcx, 0xb717b75da9983018 + +So RCX is 0xb717b75da9983018. Then, the instruction uses ECX, which is the lower 32 bits of RCX. So ECX is 0xa9983018. + +Let me compute that value in hex. Let's break down 0xa9983018. + +Breaking into bytes: 0xA9 0x98 0x30 0x18. So as a 32-bit value, it's 0xA9983018. + +Now, the index is the lower 16 bits of ECX: 0x3018 (which is 12312). The width is the upper 16 bits: 0xA998 (which is 43416). + +But for a 32-bit source (EBX is 0x5ad3b9b4), the BEXTR instruction is supposed to extract 'width' bits starting at 'index'. Since both index and width are way beyond 32 bits, the result should be zero. But the user says the CPU returns 0x5a. + +Hmm. Maybe I'm missing something here. Let me think again. Perhaps the operand size for BEXTR is determined by the destination. In the instruction "bextr eax, ebx, ecx", the destination is EAX (32 bits), so the operand size is 32 bits. Therefore, the source (ebx) is treated as a 32-bit value, and the index/width are 16 bits each. + +But if the index is 0x3018 (which is 12312), which is way beyond 31 (the maximum bit index for 32 bits), then according to Intel's documentation, the instruction may return zero. However, the user reports that the CPU returns 0x5a. How is this possible? + +Wait, maybe the index and width are not 16 bits each. Maybe in 32-bit operand size, the index and width are 8 bits each. Let me check the BEXTR instruction's documentation. + +According to Intel's documentation, the BEXTR instruction has the following operands: + +BEXTR r/m64, r64, r64 (for 64-bit operand size) +BEXTR r/m32, r32, r32 (for 32-bit operand size) + +The third operand (the index/width) is treated as follows: the lower 8 bits contain the index, and the upper 8 bits contain the width. Wait, maybe I was wrong earlier. Maybe for 32-bit operand size, the index and width are each 8 bits. + +If that's the case, then for the ECX value 0xA9983018, when considered as a 32-bit operand, the lower 8 bits are 0x18 (24) and the upper 8 bits are 0xA9 (169). So the index is 24, width is 169. But for a 32-bit source, the maximum width is 32. So width 169 is larger than 32, so the effective width is 32 - index. So if index is 24, the maximum possible width is 8 (32 - 24). So the instruction would extract 8 bits starting at bit 24 of the source. + +Let's check the source value: EBX is 0x5ad3b9b4. Let's represent this in binary. + +0x5ad3b9b4 in binary is: + +Let's break it down into bytes: + +0x5a d3 b9 b4. + +In binary, each byte is 8 bits. Let's write them out: + +0x5a is 01011010 +0xd3 is 11010011 +0xb9 is 10111001 +0xb4 is 10110100 + +So the 32-bit value is: + +01011010 11010011 10111001 10110100 + +Now, the index is 24 (so the 24th bit, counting from 0). Let's count from the left (MSB) or right (LSB)? + +Wait, in BEXTR, the index is the starting bit position. For little-endian, the bits are numbered with the least significant bit as 0. So for example, bit 0 is the least significant bit (LSB), bit 31 is the most significant bit (MSB) of the 32-bit value. + +So the source is 0x5ad3b9b4. Let's write the bits in order from bit 0 (LSB) to bit 31 (MSB). + +But to find bit 24, we need to look at the 24th bit. Let's break down the 32-bit value: + +The value is 0x5ad3b9b4. Let's convert to binary: + +0x5a is 01011010 (MSB of the first byte) +But since it's a 32-bit little-endian value, the actual order is: + +The bytes are stored as [0xb4, 0xb9, 0xd3, 0x5a] in memory for little-endian. But when treated as a 32-bit integer, the bits are ordered with the least significant byte first. However, when considering individual bits, the bit positions are numbered from 0 (LSB) to 31 (MSB). + +So the 32-bit value 0x5ad3b9b4 in binary (as a 32-bit unsigned integer) is: + +Let me compute it step by step. + +0x5ad3b9b4 = 0x5a << 24 | 0xd3 << 16 | 0xb9 << 8 | 0xb4. + +In binary, as a 32-bit number: + +Breaking down each hex digit into 4 bits: + +0x5a is 0101 1010 +0xd3 is 1101 0011 +0xb9 is 1011 1001 +0xb4 is 1011 0100 + +So the full 32-bit value is: + +01011010 11010011 10111001 10110100 + +Now, the bits are numbered from 0 (LSB) to 31 (MSB). So the first byte (0xb4) is bits 7-0, next byte (0xb9) is bits 15-8, then 0xd3 is bits 23-16, and 0x5a is bits 31-24. + +So bit 24 is the 24th bit. Let's count: + +The first byte (0xb4) is bits 0-7. + +Second byte (0xb9): bits 8-15. + +Third byte (0xd3): bits 16-23. + +Fourth byte (0x5a): bits 24-31. + +So bit 24 is the first bit of the fourth byte. The fourth byte is 0x5a in hex, which is 01011010 in binary. So bit 24 is the 0th bit of this byte? Wait, no. Wait, the fourth byte is the most significant byte. Let's think again. + +The 32-bit value is represented as four bytes: + +Byte 0 (LSB): 0xb4 (bits 0-7) +Byte 1: 0xb9 (bits 8-15) +Byte 2: 0xd3 (bits 16-23) +Byte 3 (MSB): 0x5a (bits 24-31) + +So bit 24 is the 0th bit of the third byte (0x5a). Wait, no. The third byte is 0xd3, which is bits 16-23. The fourth byte is 0x5a, which is bits 24-31. So bit 24 is the 0th bit of the fourth byte (0x5a). + +The fourth byte is 0x5a in hex, which is 01011010 in binary. The bits are: + +bit 24: 0 +bit 25: 1 +bit 26: 0 +bit 27: 1 +bit 28: 1 +bit 29: 0 +bit 30: 1 +bit 31: 0 + +Wait, but the binary for 0x5a is 01011010. So the bits are: + +bit 24: 0 (LSB of the fourth byte) +bit 25: 1 +bit 26: 0 +bit 27: 1 +bit 28: 1 +bit 29: 0 +bit 30: 1 +bit 31: 0 (MSB of the fourth byte) + +Wait, no. Wait, the fourth byte is 0x5a, which is 01011010. The bits are numbered from 24 to 31. So: + +bit 24: 0 (LSB of the fourth byte) +bit 25: 1 +bit 26: 0 +bit 27: 1 +bit 28: 1 +bit 29: 0 +bit 30: 1 +bit 31: 0 (MSB of the fourth byte) + +So if the index is 24, and the width is 8 (since the maximum possible width is 32 - 24 = 8), then the BEXTR instruction would extract 8 bits starting at bit 24. That would be the entire fourth byte, which is 0x5a. + +Ah! So the result is 0x5a. That's why the CPU returns 0x5a. + +So the confusion was in how the index and width are determined. For a 32-bit operand size, the index is the lower 8 bits of the third operand (ECX), and the width is the upper 8 bits. + +In this case, ECX is 0xA9983018. The lower 8 bits are 0x18 (24), and the upper 8 bits are 0xA9 (169). But since the width can't exceed 32 - index (which is 32 - 24 = 8), the effective width is 8. So the instruction extracts 8 bits starting at bit 24, which is the fourth byte of the source, giving 0x5a. + +So the CPU returns 0x5a. + +Now, the user's question is about why the CPU returns this value, but the problem might be to explain this scenario.

The user provided a bug report from QEMU's source code. The specific line in question is target-arm/helper.c:5493, where there's a test that's supposedly always true. The code in question is checking if (env->uncached_cpsr & CPSR_M) != CPSR_USER. + +First, I need to understand what CPSR_M and CPSR_USER are. From the cpu.h file, CPSR_M is defined as 0x1fU, which is a bitmask for the mode bits in the CPSR (Current Program Status Register). The CPSR_USER is defined as CPSR_NZCV | CPSR_Q | CPSR_GE. Wait, but CPSR_M is 0x1f, which is 5 bits for the mode. CPSR_USER is a combination of other flags. But the code is checking if the mode bits (CPSR_M) are not equal to CPSR_USER. + +But if CPSR_USER doesn't include the mode bits, then when you do a bitwise AND with CPSR_M, you're only looking at the mode bits. So, CPSR_USER probably has some flags set, but the mode bits might be a different value. For example, maybe CPSR_USER's mode bits are not the same as the user mode. Wait, maybe CPSR_USER is supposed to represent the user mode? Or perhaps it's a combination of flags that includes other things. + +Wait, the error message says that the expression '(X & 0x1f) != 0xf80f0000' is always true. Wait, the original code is checking if (X & CPSR_M) != CPSR_USER. But CPSR_M is 0x1f (5 bits), and CPSR_USER is defined as CPSR_NZCV | CPSR_Q | CPSR_GE. Let's see what those are. CPSR_NZCV is probably the N, Z, C, V flags, which are bits 31, 30, 29, 28. CPSR_Q is the overflow flag, maybe bit 27. CPSR_GE is the GE flags, bits 19-16. So when you OR them together, the result would have bits set in positions that are not part of the CPSR_M (which is 0x1f, bits 0-4). Therefore, when you do (X & CPSR_M) you're only looking at bits 0-4. But CPSR_USER, when you mask with CPSR_M, would be 0, because all those ORed bits are outside the 0x1f mask. Wait, no. Because CPSR_USER is the combination of those flags, which are in higher bits. So when you do (X & CPSR_M), you're only checking the mode bits. So CPSR_USER, when ANDed with CPSR_M, would be zero? Unless CPSR_USER includes some bits in the lower 5 bits. But according to the definition, CPSR_USER is made up of other flags that are not in the mode bits. + +So the check (env->uncached_cpsr & CPSR_M) != CPSR_USER is comparing the mode bits (which are 5 bits) to CPSR_USER, which is a combination of other flags. But since CPSR_USER includes bits outside of the 0x1f mask, when you do (X & CPSR_M), you're only looking at the mode bits, and comparing them to CPSR_USER, which when masked would be zero. Wait, no. Let me think again. + +If CPSR_USER is defined as (CPSR_NZCV | CPSR_Q | CPSR_GE), and those are bits outside the 0x1f mask, then when you compute CPSR_USER, it's a value where the lower 5 bits (the mode bits) are zero. Therefore, when you do (X & CPSR_M) != CPSR_USER, you're comparing the mode bits of X to a value that is zero in those bits. So the check would be whether the mode bits are not equal to zero. But CPSR_M is 0x1f, so (X & CPSR_M) would be the mode bits. The check is whether that value is not equal to CPSR_USER. But CPSR_USER, when you look at its lower 5 bits, is zero. So the expression is equivalent to (mode_bits != 0xf80f0000), but that doesn't make sense because 0xf80f0000 is way higher than 0x1f. Wait, the user's error message says the expression '(X & 0x1f) != 0xf80f0000' is always true. That must be a typo or misunderstanding. Because 0xf80f0000 is 32 bits, but when you mask with 0x1f (5 bits), you get the lower 5 bits of that value. Let's compute 0xf80f0000 & 0x1f. The hexadecimal value 0xf80f0000 in binary is 11111000000011110000000000000000. The lower 5 bits are the last five bits, which are 00000. So 0xf80f0000 & 0x1f is 0x00. Therefore, the expression (X & 0x1f) != 0xf80f0000 is equivalent to (X & 0x1f) != 0. Because 0xf80f0000 when masked is 0. Therefore, the check (X & 0x1f) != 0 is always true except when X's lower 5 bits are zero. But in the code, the check is whether (X & CPSR_M) != CPSR_USER. Since CPSR_USER when masked is zero, the check is equivalent to (mode_bits != 0). But the error message says that the expression is always true. That would mean that the code is checking if the mode bits are not zero, which is always true because the mode bits can't be zero. ARM processors have specific mode bits, and user mode is one of them. For example, user mode's mode bits are 0b10000 (I think), which is 16 (0x10). So the mode bits are always non-zero. Therefore, the expression (X & 0x1f) != 0 is always true, which is what the error message is pointing out. But the original code is written as (X & CPSR_M) != CPSR_USER. But since CPSR_USER when masked is zero, the check is equivalent to (X & CPSR_M) != 0. Which is always true because the mode bits can't be zero. Hence, the test is redundant. + +So the bug here is a style issue where the code is written in a way that the test is always true. The category for this would be runtime?

This seems to be a logical error in the code that would always evaluate to true, which is a runtime error in logic. However, the problem is not causing a crash but is a redundant check.

Since this is about a condition check in helper code that's always true, perhaps it's a runtime error. But the problem is more about code style and logic, which might be considered a runtime issue. Alternatively, maybe it's not causing any runtime problem but is a style issue. However, the error message says "Expression ... is always true", which is a style check warning, but the actual category depends on the options given. The options are instruction, syscall, runtime. + +Since it's a logical error in the code that's part of the CPU mode checking, which affects the execution flow, it's a runtime error. But maybe the original intent was to check if the mode is not user mode. However, the code is written incorrectly because CPSR_USER is not the user mode value. Wait, maybe CPSR_USER should be the user mode value. Let me check. + +In ARM, the CPSR's mode bits (bits 0-4) determine the processor mode. For example, User mode is 0b10000 (16, 0x10). System mode is 0b11111 (31, 0x1f?), but I'm not sure. The CPSR_M is the mask 0x1f. CPSR_USER is defined as CPSR_NZCV | CPSR_Q | CPSR_GE. That seems incorrect. Because CPSR_USER should represent the CPSR value when in user mode, which includes the mode bits. But according to the code, CPSR_USER is the combination of other flags but not the mode bits. Therefore, the check (env->uncached_cpsr & CPSR_M) != CPSR_USER is incorrect because CPSR_USER doesn't include the mode bits. The correct check would be to compare the mode bits to the user mode value (e.g., 0x10 or whatever the user mode is). So the code is trying to check if the current mode is not user mode, but it's doing it incorrectly. + +The problem here is that the code is using CPSR_USER, which is a combination of other flags, but the check is only on the mode bits.

The error message mentions an exception 0x8, which on ARM typically corresponds to a Prefetch Abort or Data Abort, but I need to check. + +First, looking at the exception number. On ARM, exception vectors are numbered. For example, exception 0x8 might be a Data Abort. For Cortex-M33, which is an ARMv8-M architecture, the exception numbers might differ slightly. But in general, exceptions like 0x8 are often related to memory access issues. The stack trace shows R15 (PC) is at fffeaf5c, and the XPSR (Program Status Register) has some flags set. The user mentions that the test uses nested functions, which generate trampolines on the stack. Trampolines involve creating executable code on the stack, which can lead to issues if the stack isn't executable or if there's an invalid memory access. + +The problem occurs with -Os (optimize for size) but not with -O2. This suggests that the optimization level changes the code generation in a way that leads to an invalid instruction or memory access. Since the test case works at -O2, maybe the trampoline is generated correctly there, but with -Os, perhaps the code is different, leading to an invalid PC value or an attempt to execute non-executable memory.

Alternatively, the generated code might have an invalid address in the PC, causing a Prefetch Abort when trying to fetch an instruction from an invalid location. + +Looking at the registers, R15 is fffeaf5c. The address 0xfffeaf5c might be within a memory area that isn't properly mapped or isn't executable in QEMU's simulation. But why would that happen?

The error message also says "handle_cpu_signal received signal outside vCPU context @ pc=0x6033c908".

However, the user is confused because they might expect that the presence of a plugin's callback shouldn't affect the number of elements loaded, unless the callback actually represents an invalid memory access. + +But maybe the code is not handling MMIO correctly here. If the memory callback is for something like a watchpoint or a virtualized device, then accessing that address should be allowed (as the plugin handles it), but the code is treating it as an error because flags & ~TLB_WATCHPOINT is non-zero. For example, if probe_access_flags returns TLB_MMIO, and if that's not part of the ~TLB_WATCHPOINT mask, then maybe the code is incorrectly interpreting it as an invalid access. Wait, the code does flags & ~TLB_WATCHPOINT.

Therefore, the problem must be that QEMU is not handling the unshare syscall correctly when emulating the x86_64 user-space. Maybe QEMU's user-mode emulation doesn't fully support certain syscalls, or there's a bug in how it handles CLONE_NEWUSER. + +So, this seems like a syscall issue. The problem is that QEMU isn't correctly handling the unshare system call, leading to an invalid argument error.
