--- Comment #2 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Jennifer Schmitz <jschm...@gcc.gnu.org>: https://gcc.gnu.org/g:313aa733e22b654ff822b867018b13ceb624c13a commit r15-3085-g313aa733e22b654ff822b867018b13ceb624c13a Author: Jennifer Schmitz <jschm...@nvidia.com> Date: Mon Aug 19 08:42:55 2024 -0700 PR target/116365: Add user-friendly arguments to --param aarch64-autovec-preference=N The param aarch64-autovec-preference=N is a useful tool for testing auto-vectorisation in GCC as it allows the user to force a particular strategy. So far, N could be a numerical value between 0 and 4. This patch replaces the numerical values by more user-friendly names to distinguish the options. The patch was bootstrapped and regtested on aarch64-linux-gnu, no regression. Ok for mainline?
