git.ipfire.org Git - thirdparty/gcc.git/commit - gcc/config/aarch64/aarch64-fusion-pairs.def
Enable instruction fusion of dependent AESE; AESMC and AESD; AESIMC pairs.
This can give up to 2x speedup on many AArch64 implementations. Also model
the crypto instructions on Cortex-A57 according to the Optimization Guide.
gcc/
* config/aarch64/aarch64.c (cortexa53_tunings): Enable AES fusion.
(cortexa57_tunings): Likewise.
(cortexa72_tunings): Likewise.
(arch_macro_fusion_pair_p): Add support for AES fusion.
* config/aarch64/aarch64-fusion-pairs.def: Add AES_AESMC entry.
* config/arm/aarch-common.c (aarch_crypto_can_dual_issue):
Allow virtual registers before reload so early scheduling works.
* config/arm/cortex-a57.md (cortex_a57_crypto_simple): Use
correct latency and pipeline.
(cortex_a57_crypto_complex): Likewise.
(cortex_a57_crypto_xor): Likewise.
(define_bypass): Add AES bypass.
