Hi, The x86 (32-bit) disassembler can't disassemble any of the following: 0x2b 0xc9 0x8a 0xc8 0xdd 0x04 0x24 These are: subl %ecx, %ecx movb %al, %cl fldl (%esp) I've attached patches to bug#8873 which fix all these issues, but I'm not confident that I've fixed them the right way. The first two problems are caused by the instructions setting 'isCodeGenOnly = 1', which causes tblgen to miss them from the disassembler's table...

For example, I execute the following command sequences: H:\CI\bld\compilers\musl\src\math\i386>type sqrt.s #.globl _sqrt .global sqrt #.type sqrt, at function #_sqrt: sqrt: fldl 4(%esp) fsqrt fstsw %ax sub $12,%esp fld %st(0) fstpt (%esp) mov (%esp),%ecx and $0x7ff,%ecx cmp $0x400,%ecx jnz 1f and $0x200,%eax sub $0x100,%eax sub %eax,(%esp) fstp %st(0) fldt (%esp)...

Hi Andi, Four patches: - clean up asm/bugs.h, by moving all the C code into its own C file - split identify_cpu() into boot and secondary variants, so that boot-time setup functions can be marked __init - repost of the COMPAT_VDSO patches with a bit more robustness from unknown DT_tags, and functions marked __init, since all this is boot-time only setup. Thanks, J --
