From: Tejas Belagod <belagod@gcc.gnu.org> To: gcc-cvs@gcc.gnu.org Subject: [gcc r13-5269] AArch64: Gate various crypto intrinsics availability based on features Date: Fri, 20 Jan 2023 09:44:28 +0000 (GMT) [thread overview] Message-ID: <20230120094428.73B5F3858D20@sourceware.org> (raw) https://gcc.gnu.org/g:99ea0d7611605d2d1a67a6021cb78f0bdd5c609b commit r13-5269-g99ea0d7611605d2d1a67a6021cb78f0bdd5c609b Author: Tejas Belagod <tejas.belagod@arm.com> Date: Thu Dec 15 07:57:50 2022 +0000 AArch64: Gate various crypto intrinsics availability based on features The 64-bit variant of PMULL{2} and AES instructions are available if FEAT_AES is implemented according to the Arm ARM [1]. Similarly FEAT_SHA1 and FEAT_SHA256 enable the use of SHA1 and SHA256 instruction variants. This patch fixes arm_neon.h to correctly reflect the feature availability based on '+aes' and '+sha2' as opposed to the ambiguous catch-all '+crypto'. [1] Section D17.2.61, C7.2.215 2022-01-11 Tejas Belagod <tejas.belagod@arm.com> gcc/ChangeLog: * config/aarch64/arm_neon.h (vmull_p64, vmull_high_p64, vaeseq_u8, vaesdq_u8, vaesmcq_u8, vaesimcq_u8): Gate under "nothing+aes". (vsha1*_u32, vsha256*_u32): Gate under "nothing+sha2". gcc/testsuite/ChangeLog: * gcc.target/aarch64/acle/pmull64.c: New. * gcc.target/aarch64/aes-fuse-1.c: Replace '+crypto' with corresponding feature flag based on the intrinsic. * gcc.target/aarch64/aes-fuse-2.c: Likewise. * gcc.target/aarch64/aes_1.c: Likewise. * gcc.target/aarch64/aes_2.c: Likewise. * gcc.target/aarch64/aes_xor_combine.c: Likewise. * gcc.target/aarch64/sha1_1.c: Likewise. * gcc.target/aarch64/sha256_1.c: Likewise. * gcc.target/aarch64/target_attr_crypto_ice_1.c: Likewise.
