Let me read through the problem again carefully. + +The user is building lib32-qemu for mips o32 using Yocto and qemumips64. They encountered an error where the assembler reports "branch out of range" at several lines in AArch64InstPrinter.c. This happens when using gcc 9.1, but not with gcc 8.3 or without the '-Og' optimization flag. + +Hmm, the issue seems to be related to the compiler generating code that results in branches being out of range. Since it's specific to a certain GCC version and optimization level, maybe it's an issue with how the compiler is handling the assembly output for AArch64 instructions. + +Looking at the possible categories: mistranslation involves incorrect mapping from source to target architecture, which could lead to such issues. The problem occurs during assembly lowering, so 'assembly' might be relevant too. However, since it's about optimization and the compiler's behavior, I think 'mistranslation' is more accurate because it's about how instructions are being translated into machine code that exceeds the allowed range. + +Alternatively, if the issue is within capstone when generating assembly, it could fall under 'assembly'. But given that GCC 9.1 behaves differently and causes this error, which might be a miscompilation or incorrect instruction handling, 'mistranslation' seems more fitting as it's about semantic mapping issues during compilation. + +Wait, the user is using capstone for disassembling, so perhaps capstone isn't generating correct assembly, leading to GCC having trouble. But if the problem arises when compiling with '-Og', maybe it's a compiler issue rather than capstone's. However, the error message points to lines in AArch64InstPrinter.c, which is part of capstone. + +I'm a bit confused now. The bug report mentions that removing '-Og' fixes it with GCC 9.1, so perhaps it's an optimization-related problem where branches are being reordered or generated in a way that makes them too far apart for the instruction set. That sounds like a mistranslation issue because it's about how the compiler is mapping high-level code to machine instructions, specifically AArch64. + +Alternatively, if capstone isn't handling certain cases correctly and GCC 9.1 is catching it when optimizations are applied, maybe it's an assembly lowering problem within capstone itself. So 'assembly' could be the category because it's during the process of converting higher-level code to assembly instructions where the issue occurs. + +But considering that the error happens in the compiler output (assembler messages), and it's related to optimization flags, I'm more inclined towards it being a mistranslation issue by the compiler. However, since the problem is within capstone's AArch64InstPrinter.c file, maybe 'assembly' is the right category because it's about generating correct assembly code. + +Wait, but capstone is a disassembler and assembler library. If there's a bug in how it generates assembly instructions that leads to branches being out of range when using a specific GCC version, then yes, it's an assembly lowering issue within capstone. So the category should be 'assembly'. + +But I'm still not entirely sure. The error message is from GCC during compilation, which might suggest that capstone isn't generating valid C code or headers that lead to correct assembly. Alternatively, perhaps it's a bug in how the compiler handles certain optimizations when including capstone-generated files. + +Given that the user is using capstone and the errors are in AArch64InstPrinter.c, I think the problem lies within capstone's assembly generation. So 'assembly' would be the appropriate category. +</think> + +The issue arises during the compilation of code generated by Capstone for AArch64, leading to branch instructions being out of range when using GCC 9.1 with optimization. This points to a problem in how Capstone translates higher-level instructions into valid assembly, making it an 'assembly' lowering issue. + +**category: assembly** \ No newline at end of file |
