Make the output of codecode/x86_64.py reproducible #108

lamby · 2020-07-04T10:49:07Z

Whilst working on the Reproducible Builds effort I noticed that PeachPy was generating code/documentation in a non-deterministic manner. This is because it was iterating over data structures in a nondeterministic manner which resultd in (non-normative) differences such as:

  -<li><p>VEXPANDPD(ymm{k}{z}, ymm/m256)    [AVX512F and AVX512VL]</p></li>
   <li><p>VEXPANDPD(xmm{k}{z}, xmm/m128)    [AVX512VL]</p></li>
  +<li><p>VEXPANDPD(ymm{k}{z}, ymm/m256)    [AVX512F and AVX512VL]</p></li>

and:

  -        self._implicit_out_regs = {0: 7, 2: 7}
  +        self._implicit_out_regs = {2: 7, 0: 7}

This PR just sorts a bunch of stuff prior to output.

(This was originally filed in Debian as #964186.)
