Re: [Tinycc-devel] Optimizing for avx512

[Christian Jullien]

You can perhaps combine the best of the two world:
- compile with gcc and all optimizations (esp. avx512) the C module you want to 
speedup
- compile all other modules with tcc and link them with tcc.

C.

Thank you for feedback. I understand what are the limits of tcc. In my specific 
problem, I am trying to speed up user-provided expression in a simulation of 
100 paths. Can I use the avx512 build-in - e.g. work on 8 double precision 
values with one operation - practically reducing the 100 evaluations to 13 
(100/8) ?

User expressions are all in the form that can be handle by AVX SIMD 
instructions: add, multiple, … 

Thanks, yair.
