Mathias Parnaudeau	d4358ddba7	Add autodetection of ppc64 architectures ... That allows 'make -j profile-build' work on ppc64 architectures, setting the use of the appropriate SIMD extension, Altivec or VSX. For VSX, gcc allows to map SSE2 intrinsics and get benefit of the existing SIMD code. On PowerMac G5, using altivec provides a performance improvement of 30%. On Talos 2, using vsx provides a performance improvement of 120%. closes https://github.com/official-stockfish/Stockfish/pull/5624 No functional change	2024-10-12 16:30:44 +02:00
Wencey Wang	93869d5d0a	Fix native arch builds on loongarch64 ... Adds support for LSX and LASX closes https://github.com/official-stockfish/Stockfish/pull/5600 No functional change	2024-09-28 17:12:12 +02:00
Torsten Hellwig	6c02329860	Fix dotprod detection ... This fixes the detection of dotprod capable CPUs. Previously it looked for the `dotprod` flag, but this does not exist (https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/tree/arch/arm64/kernel/cpuinfo.c#n50). The correct flag that specifies the dotprod capability is the `asimddp` flag. fixes #4931 closes https://github.com/official-stockfish/Stockfish/pull/4991 No functional change	2024-01-17 18:32:20 +01:00
ppigazzini	8724503d9c	Simplify the code to get the native flags ... closes https://github.com/official-stockfish/Stockfish/pull/4908 No functional change	2023-12-10 23:18:21 +01:00
Joost VandeVondele	708319a433	Enable a default native ARCH ... uses a posix compatible script to find the native arch. (based on ppigazzini's https://github.com/ppigazzini/stockfish-downloader ) use that native arch by default, no changes if ARCH is specified explicitly. SF can now be compiled in an optimal way simply using make -j profile-build closes https://github.com/official-stockfish/Stockfish/pull/4777 No functional change	2023-09-22 19:06:37 +02:00
