--- Comment #11 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Robin Dapp <rd...@gcc.gnu.org>: https://gcc.gnu.org/g:32b74c9e1d46932a4bbb1f46353bfc43c702c20a commit r14-4868-g32b74c9e1d46932a4bbb1f46353bfc43c702c20a Author: Robin Dapp <rd...@ventanamicro.com> Date: Sun Oct 15 22:36:59 2023 +0200 vect: Allow same precision for bit-precision conversions. In PR111794 we miss a vectorization because on riscv type precision and mode precision differ for mask types. We can still vectorize when allowing assignments with the same precision for dest and source which is what this patch does. gcc/ChangeLog: PR tree-optimization/111794 * tree-vect-stmts.cc (vectorizable_assignment): Add same-precision exception for dest and source. gcc/testsuite/ChangeLog: * gcc.target/riscv/rvv/autovec/slp-mask-1.c: New test. * gcc.target/riscv/rvv/autovec/slp-mask-run-1.c: New test.
