From: Saurabh Jha <saurabh....@arm.com> This patch series a revised version of an earlier patch series: https://gcc.gnu.org/pipermail/gcc-patches/2024-September/662951.html.
The main change in this patch series is the introduction of the two unspecs, UNSPEC_COND_SMAX and UNSPEC_COND_SMIN, and using them for existing minmax instructions and for the code generation of faminmax instructions. Other changes in this patch series are to address review comments: 1. [PATCH 1] Removing stray gcc/testsuite/gcc.target/aarch64/aminmax.h. 2. [PATCH 1] Fixing formatting in new iterators in iterators.md. 3. [PATCH 1] Using pragma "+sve+faminmax" in test cases. Remove options directive. 4. [PATCH 2] Move instruction pattern to aarch64-sve2.md. 5. [PATCH 2] Fix use of operand 2. 6. [PATCH 2] Fix use of assemble directive. 7. [PATCH 2] Using pragma "+sve+faminmax" and remove them from options. 8. [PATCH 2] New test cases to make sure we are not operator combine while using intrinsics. Another minor change was in aarch64-sve-builtins-base.cc where we fixed the formatting.
