--- Comment #4 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Filip Kastl <phe...@gcc.gnu.org>: https://gcc.gnu.org/g:99ec0eb32a03506142f30c158276b4131aa73fe8 commit r15-5204-g99ec0eb32a03506142f30c158276b4131aa73fe8 Author: Filip Kastl <fka...@suse.cz> Date: Wed Nov 13 16:11:14 2024 +0100 i386: Add -mveclibabi=aocl [PR56504] We currently support generating vectorized math calls to the AMD core math library (ACML) (-mveclibabi=acml). That library is end-of-life and its successor is the math library from AMD Optimizing CPU Libraries (AOCL). This patch adds support for AOCL (-mveclibabi=aocl). That significantly broadens the range of vectorized math functions optimized for AMD CPUs that GCC can generate calls to. See the edit to invoke.texi for a complete list of added functions. Compared to the list of functions in AOCL LibM docs I left out these vectorized function families: - sincos and all functions working with arrays ... Because these functions have pointer arguments and that would require a bigger rework of ix86_veclibabi_aocl(). Also, I'm not sure if GCC even ever generates calls to these functions. - linearfrac ... Because these functions are specific to the AMD library. There's no equivalent glibc function nor GCC internal function nor GCC built-in. - powx, sqrt, fabs ... Because GCC doesn't vectorize these functions into calls and uses instructions instead. I also left amd_vrd2_expm1() (the AMD docs list the function but I wasn't able to link calls to it with the current version of the library). gcc/ChangeLog: PR target/56504 * config/i386/i386-options.cc (ix86_option_override_internal): Add ix86_veclibabi_type_aocl case. * config/i386/i386-options.h (ix86_veclibabi_aocl): Add extern ix86_veclibabi_aocl(). * config/i386/i386-opts.h (enum ix86_veclibabi): Add ix86_veclibabi_type_aocl into the ix86_veclibabi enum. * config/i386/i386.cc (ix86_veclibabi_aocl): New function. * config/i386/i386.opt: Add the 'aocl' type. * doc/invoke.texi: Document -mveclibabi=aocl. gcc/testsuite/ChangeLog: PR target/56504 * gcc.target/i386/vectorize-aocl1.c: New test.
