Hi Guix,currently we patch source code and build systems to ensure that no special instructions are used that would not be portable, e.g. AVX2, SSE4.1 etc. What do you think of adding a build system option that would allow users to restore these optimizations?
The build phases that patch out these features would have to check for that build system option, much like they check the TESTS? option before attempting to run tests.
What do you think? -- Ricardo
