To: gcc-patches; +Cc: gkm, jeffreyalaw, vineetg, ewlu
From: Greg McGary <gkm@rivosinc.com>
Add option -m(no-)autovec-segment to enable/disable autovectorizer
from emitting vector segment load/store instructions. This is useful for
performance experiments.
gcc/ChangeLog:
* config/riscv/autovec.md (vec_mask_len_load_lanes, vec_mask_len_store_lanes):
Predicate with TARGET_VECTOR_AUTOVEC_SEGMENT
* gcc/config/riscv/riscv-opts.h (TARGET_VECTOR_AUTOVEC_SEGMENT): New macro.
* gcc/config/riscv/riscv.opt (-m(no-)autovec-segment): New option.
* testsuite/gcc.target/riscv/rvv/autovec/struct/*_noseg*.c,
testsuite/gcc.target/riscv/rvv/autovec/no-segment.c: New tests.
Tested-by: Edwin Lu <ewlu@rivosinc.com>
---
Added tested-by on Vineet's recommendation. Please wait for riscv precommit to
finish before committing.
