--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Author: jakub Date: Wed Jan 1 00:20:39 2020 New Revision: 279809 URL: https://gcc.gnu.org/viewcvs?rev=279809&root=gcc&view=rev Log: PR tree-optimization/93098 * match.pd (popcount): For shift amounts, use integer_onep or wi::to_widest () == cst instead of tree_to_uhwi () == cst tests. Make sure that precision is power of two larger than or equal to 16. Ensure shift is never negative. Use HOST_WIDE_INT_UC macro instead of ULL suffixed constants. Formatting fixes. * gcc.c-torture/compile/pr93098.c: New test.
