--- Comment #9 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:7d72cad143ff6933f2f90018c65d6c861c387e4d commit r16-3279-g7d72cad143ff6933f2f90018c65d6c861c387e4d Author: Tamar Christina <tamar.christ...@arm.com> Date: Tue Aug 19 10:18:04 2025 +0100 AArch64: Use vectype from SLP node instead of stmt_info [PR121536] commit g:1786be14e94bf1a7806b9dc09186f021737f0227 stops storing in STMT_VINFO_VECTYPE the vectype of the current stmt being vectorized and instead requires the use of SLP_TREE_VECTYPE for everything but data-refs. This means that STMT_VINFO_VECTYPE (stmt_info) will always be NULL and so aarch64_bool_compound_p will never properly cost predicate AND operations anymore resulting in less vectorization. This patch changes it to use SLP_TREE_VECTYPE and pass the slp_node to aarch64_bool_compound_p. gcc/ChangeLog: PR target/121536 * config/aarch64/aarch64.cc (aarch64_bool_compound_p): Use SLP_TREE_VECTYPE instead of STMT_VINFO_VECTYPE. (aarch64_adjust_stmt_cost, aarch64_vector_costs::count_ops): Pass SLP node to aarch64_bool_compound_p. gcc/testsuite/ChangeLog: PR target/121536 * g++.target/aarch64/sve/pr121536.cc: New test.
