Subject: [PATCH] RISC-V: Support vfwnmacc/vfwmsac/vfwnmsac combine lowering
Date: Wed, 28 Jun 2023 19:55:59 +0800 [thread overview]
Message-ID: <20230628115559.116166-1-juzhe.zhong@rivai.ai> (raw)
Similar to vfwmacc. Add combine patterns as follows:
For vfwnmsac:
1. (set (reg) (fma (neg (float_extend (reg))) (float_extend (reg))) (reg) )))
2. (set (reg) (fma (neg (float_extend (reg))) (reg) (reg) )))
For vfwmsac:
1. (set (reg) (fma (float_extend (reg)) (float_extend (reg))) (neg (reg)) )))
2. (set (reg) (fma (float_extend (reg)) (reg) (neg (reg)) )))
For vfwnmacc:
1. (set (reg) (fma (neg (float_extend (reg))) (float_extend (reg))) (neg (reg)) )))
2. (set (reg) (fma (neg (float_extend (reg))) (reg) (neg (reg)) )))
gcc/ChangeLog:
* config/riscv/autovec-opt.md (*double_widen_fnma<mode>): New pattern.
(*single_widen_fnma<mode>): Ditto.
(*double_widen_fms<mode>): Ditto.
(*single_widen_fms<mode>): Ditto.
(*double_widen_fnms<mode>): Ditto.
(*single_widen_fnms<mode>): Ditto.
