--- Comment #3 from GCC 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:d468718c9a097aeb8794fb1a2df6db2c1064d7f7 commit r14-6341-gd468718c9a097aeb8794fb1a2df6db2c1064d7f7 Author: Robin Dapp <rd...@ventanamicro.com> Date: Fri Dec 1 10:07:23 2023 +0100 RISC-V: Add vectorized strcmp and strncmp. This patch adds vectorized strcmp and strncmp implementations and tests. Similar to strlen, expansion is still guarded by -minline-str(n)cmp. gcc/ChangeLog: PR target/112109 * config/riscv/riscv-protos.h (expand_strcmp): Declare. * config/riscv/riscv-string.cc (riscv_expand_strcmp): Add strategy handling and delegation to scalar and vector expanders. (expand_strcmp): Vectorized implementation. * config/riscv/riscv.md: Add TARGET_VECTOR to strcmp and strncmp expander. gcc/testsuite/ChangeLog: * gcc.target/riscv/rvv/autovec/builtin/strcmp-run.c: New test. * gcc.target/riscv/rvv/autovec/builtin/strcmp.c: New test. * gcc.target/riscv/rvv/autovec/builtin/strncmp-run.c: New test. * gcc.target/riscv/rvv/autovec/builtin/strncmp.c: New test.
