I think of the BLAS algos as being very Fortran friendly, and the Fortran references never _out_perform the C implementations. (The asm implementations are of course the best.)

Be curious to know what you're thinking of here.

I've no personal experience, but people historically point to pointer aliasing as the primary thing that speeds up Fortran code vs C.

No personal experience either but discussing with people invested in high perf C, they said that `restrict` was enough to avoid aliasing issues.
