-Invalid assertion in arm_read_memory_func
-
-Hi,
-
-I think there is an invalid assertion in arm_read_memory_func:
-assert(info->endian == BFD_ENDIAN_LITTLE)
-
-I face it in the following use case: target armeb-linux (I use qemu user mode), -d in_asm -cpu any.
-
-At some point during program startup, glibc's _dl_new_object calls strlen, which is written in thumb2 mode (armv6t2). So print_insn_arm() calls arm_read_memory_func() with length==2, and info->flags == INSN_ARM_BE32, and the assert is false.
-
-If I remove the assert, execution continues OK.
-
-With the assert, I get the error message from the assert, and qemu then stalls.
-
-Can you confirm the assert can be removed? Or if not, explain me how to avoid/fix the subsequent qemu stall?
-
-Thanks
-
-The tarball contains:
-scoped1.exe
-etc/ld.so.cache
-lib/libm.so.6
-lib/libstdc++.so.6
-lib/lib.c.so.6
-lib/ld-linux-armhf.so.3
-lib/libgcc_s.so.1
-
-I can reproduce the problem with qemu-2.10.1:
-qemu-armeb -E LD_LIBRARY_PATH=$PWD/lib -cpu any -R 0 -d in_asm -L $PWD $PWD/scoped1.exe
-
-Removing '-d in_asm' works OK, because the offending assert is triggered while disassembling.
-
-BTW, the program (scoped1.exe) does abort, it is a GCC testcase I was trying to debug ;-)
-
-Removing the assert lets execution continue, but the disassembly is incorrect. Without the assert, I see:
-IN: strlen
-0x40a1a880: f000 f890  bl 0x40a1a9a4
-0x40a1a884: 4502       cmp r2, r0
-but strlen normally starts with a pld instruction.
-
-So probably print_insn_arm needs also a change like
-given = (b[1]) | (b[0] <<8)<<16 | given;
-instead of
-given = (b[1]) | (b[0] <<8)|(given << 16);
-
-
-
-This should be fixed in QEMU master by commits 6cd61517fb5217098, 7bcdbf51eeb674e4.
