[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 in...
