Re: [Capstone-users] Adding regs_access support for PPC and MIPS

[Derrick M. <der...@gm...>]

I think I am mostly done with the C implementation, and have updated the
bindings. I just need to generate the {Mips,PPC}MappingInsnOp.inc files.
The existing files for ARM and x86 seem to contain the read/write
information for every instruction, sorted by enum name.  They also say that
they were autogenerated, but I guess that isn't quite correct.  I am
thinking that I can write a Python script that reads in a YAML file, and
outputs the properly sorted inc file containing all the information
(including comments) currently in existing InsnOp.inc files.  The YAML file
will have a structure like the following:

output: "MipsMappingInsnOp.inc"
Insns:
    - enum: MIPS_INS_ADD
      example: "add $d, $t, $s"
      operands:
          - read: No
            write: Yes
          - read: Yes
            write: No
          - read: Yes
            write: No

Thoughts?
