Hello,
In the case that I feel brave enough to code support for AVX512 on asm sections, from where should I start?

This question is related to:
https://forum.lazarus.freepascal.org/index.php/topic,41572.0.html

I would like to use ZMM registers in my code and do things like these:

asm
vmovups zmm, [rax]
...
end;

wishing everyone happy pascal coding,
Schuler.

Torsten (mainly) and me are working on it.

I think a good start would be extend our testing tools to support avx512 (https://svn.freepascal.org/svn/fpc/branches/tg74/avx512/tests/utils/avx/). It does not interfere with our current work. Besides this, subscript to fpc-devel for more coordination of the necessary work.

AWESOME NEWS! Thank you.

Should I start by adding more tasm*.pp testing files at fpc/branches/tg74/avx512/tests/test/ specific for AVX512 ?

Just look at the directory I mentioned. AVX1/2 is tested using automated tools which generate automatically huge assembler files which are assembled by nasm/fasm and then the result is compared with what FPC generates.
