[Bug binutils/9982] New: Wrong disassembly printed by 'objdump' for i386


From: yuri at tsoft dot com
Subject: [Bug binutils/9982] New: Wrong disassembly printed by 'objdump' for i386 instruction beginning with '81 bd'
Date: 23 Mar 2009 08:47:12 -0000

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
