--- Comment #2 from yuri at tsoft dot com ---
The symbol in question is truncated, it had the dollar sign and more characters
in the end. In its complete form binutils does demangle it correctly. It
resulted from the C++ lambda function.

Sorry for the disturbance!

[Bug binutils/9961] New: objdump disassembles invalid i386 instruction as valid

2009-03-17 Thread yuri at tsoft dot com 
I look at the line in disassembled code:
c7 2b 00 00 00 00movl   $0x0,(%ebx)
This should be an invalid instruction.
Intel manual (253666.pdf/253667.pdf) only defines c7/0 for the first instruction
byte c7 and the above instruction would be c7/5.

I used objdump that is currently in FreeBSD-7.1-STABLE. So the version is a bit
older.

[Bug binutils/9982] New: Wrong disassembly printed by 'objdump' for i386 instruction beginning with '81 bd'

2009-03-23 Thread yuri at tsoft dot com 
I spotted the following line in the objdump output:
81 bd 38 08 0c 2e 01 cmpl   $0xd74e201,0x2e0c0838(%ebp)

Instruction is:
81 /7 id CMP r/m32,imm32
Mod in bd is 10b, RM in bd is 101b therefore 38 is SIB byte.
Instruction should be:
cmpl   (%edi+%eax+0xd74e201),imm32

[Bug binutils/9983] New: Wrong disassembly printed by 'objdump' for i386 'sete' instruction beginning with '0f 94'

2009-03-23 Thread yuri at tsoft dot com 
I spotted then following lines in objdump output:
   4:   0f 94 84 24 20 10 00sete   0x1020(%esp)
   b:   00

Instruction 'sete   0x1020(%esp)' is correct, but the following 00 byte still
belongs to 'sete' instruction.

I believe that the correct fix for all such issues is to make 'as' and 'objdump'
to work off the same instruction definitions.
