[LLVMdev] registerSize on X86 confused?
Hi, In file X86DisassemblerDecoder.c, we have function readPrefixes() with below code: ..... } else if (insn->mode == MODE_32BIT) { insn->registerSize = (hasOpSize ? 2 : 4); insn->addressSize = (hasAdSize ? 2 : 4); insn->displacementSize = (hasAdSize ? 2 : 4); insn->immediateSize = (hasOpSize ? 2 : 4); } .... This is confused to me: so we have registerSize to be either 2 or 4 bytes. But we might have instruction like: adc al, 0x89 This case we should have registerSi...
