--- Comment #17 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Tamar Christina <tnfch...@gcc.gnu.org>: https://gcc.gnu.org/g:735edbf1e2479fa2323a2b4a9714fae1a0925f74 commit r15-1809-g735edbf1e2479fa2323a2b4a9714fae1a0925f74 Author: Tamar Christina <tamar.christ...@arm.com> Date: Wed Jul 3 09:31:09 2024 +0100 ivopts: replace constant_multiple_of with aff_combination_constant_multiple_p [PR114932] The current implementation of constant_multiple_of is doing a more limited version of aff_combination_constant_multiple_p. The only non-debug usage of constant_multiple_of will proceed with the values as affine trees. There is scope for further optimization here, namely I believe that if constant_multiple_of returns the aff_tree after the conversion then get_computation_aff_1 can use it instead of manually creating the aff_tree. However I think it makes sense to first commit this smaller change and then incrementally change things. gcc/ChangeLog: PR tree-optimization/114932 * tree-ssa-loop-ivopts.cc (constant_multiple_of): Use aff_combination_constant_multiple_p instead.
