Title: Opcode Table.
Post by: nobody on December 21, 2008, 04:20:46 PM

Hi

I'm writing a length dissasembler.

I read somewhere that NASM's source code would have datastructures that I could copy into a program to produce an opcode table of lengths(or types anyway). Could you halp speed things up for me and tell me where, like what file.

Cheers.

You probably want "insns.dat" which is created by a perl script when compiling the source code.  I have put the latest version here:
