When discussing #HPC, there’s always this question about performances against reproducibility. #Guix considers that most performance-critical software already include multiple versions of “hot” routines. Thus Guix only specifies very few packages lacking function multi-versioning (FMV).

What would be the point to pass ’-march’ compiler option to compile CMake itself? The loose of CMake binary portability isn’t paid, no?
