From: Avinash Jayakar <[email protected]> Hi,
Addressed the comments in https://gcc.gnu.org/pipermail/gcc-patches/2026-June/720748.html Bootstrapped and regtested on powerpc64le-linux with no regressions. Ok for trunk? Changes from v1: - Update commit header and message - Add subheading to AES documentation - Move AES builtins to future-vsx stanza Thanks, Avinash Jayakar This patch fixes few implementations issues for the AES builtins in powerpc in documentation, testcases and builtin definition. 2026-06-26 Avinash Jayakar <[email protected]> gcc/ChangeLog: * config/rs6000/rs6000-builtins.def: Move AES builtins to future-vsx stanza. * doc/extend.texi: Add subheading for AES builtins. gcc/testsuite/ChangeLog: * gcc.target/powerpc/aes-builtin-1.c: Add future_compile_ok and lp64 testsuite directive. * gcc.target/powerpc/aes-builtin-2.c: Add future_compile_ok and lp64 testsuite directive. * gcc.target/powerpc/aes-builtin-3.c: Add future_compile_ok and lp64 testsuite directive. --- gcc/config/rs6000/rs6000-builtins.def | 91 +++++++++---------- gcc/doc/extend.texi | 2 + .../gcc.target/powerpc/aes-builtin-1.c | 2 + .../gcc.target/powerpc/aes-builtin-2.c | 2 + .../gcc.target/powerpc/aes-builtin-3.c | 2 + 5 files changed, 53 insertions(+), 46 deletions(-) diff --git a/gcc/config/rs6000/rs6000-builtins.def b/gcc/config/rs6000/rs6000-builtins.def index 172a97adaa8..d2b2f0d5527 100644 --- a/gcc/config/rs6000/rs6000-builtins.def +++ b/gcc/config/rs6000/rs6000-builtins.def @@ -3925,52 +3925,6 @@ void __builtin_vsx_stxvp (v256, unsigned long, const v256 *); STXVP nothing {mma,pair} -[future] - const v256 __builtin_aes_encrypt_paired (v256, v256, const int<2>); - XXAESENCP xxaesencp {} - - const v256 __builtin_aes128_encrypt_paired (v256, v256); - XXAES128ENCP xxaes128encp {} - - const v256 __builtin_aes192_encrypt_paired (v256, v256); - XXAES192ENCP xxaes192encp {} - - const v256 __builtin_aes256_encrypt_paired (v256, v256); - XXAES256ENCP xxaes256encp {} - - const v256 __builtin_aes_decrypt_paired (v256, v256, const int<2>); - XXAESDECP xxaesdecp {} - - const v256 __builtin_aes128_decrypt_paired (v256, v256); - XXAES128DECP xxaes128decp {} - - const v256 __builtin_aes192_decrypt_paired (v256, v256); - XXAES192DECP xxaes192decp {} - - const v256 __builtin_aes256_decrypt_paired (v256, v256); - XXAES256DECP xxaes256decp {} - - const v256 __builtin_aes_genlastkey_paired (v256, const int<2>); - XXAESGENLKP xxaesgenlkp {} - - const v256 __builtin_aes128_genlastkey_paired (v256); - XXAES128GENLKP xxaes128genlkp {} - - const v256 __builtin_aes192_genlastkey_paired (v256); - XXAES192GENLKP xxaes192genlkp {} - - const v256 __builtin_aes256_genlastkey_paired (v256); - XXAES256GENLKP xxaes256genlkp {} - - const vuc __builtin_galois_field_mult (vuc, vuc, const int<1>); - XXGFMUL128 xxgfmul128 {} - - const vuc __builtin_galois_field_mult_gcm (vuc, vuc); - XXGFMUL128GCM xxgfmul128gcm {} - - const vuc __builtin_galois_field_mult_xts (vuc, vuc); - XXGFMUL128XTS xxgfmul128xts {} - [future-vsx] const vus __builtin_vsx_xvmulhuh (vus, vus); XVMULHUH umulv8hi3_highpart {} @@ -4042,3 +3996,48 @@ const vuq __builtin_vsx_xsrebase3t3uqm (vuq, vuq, vuq); XSREBASE3T3UQM vsx_xsrebase3t3uqm {} + + const v256 __builtin_aes_encrypt_paired (v256, v256, const int<2>); + XXAESENCP xxaesencp {} + + const v256 __builtin_aes128_encrypt_paired (v256, v256); + XXAES128ENCP xxaes128encp {} + + const v256 __builtin_aes192_encrypt_paired (v256, v256); + XXAES192ENCP xxaes192encp {} + + const v256 __builtin_aes256_encrypt_paired (v256, v256); + XXAES256ENCP xxaes256encp {} + + const v256 __builtin_aes_decrypt_paired (v256, v256, const int<2>); + XXAESDECP xxaesdecp {} + + const v256 __builtin_aes128_decrypt_paired (v256, v256); + XXAES128DECP xxaes128decp {} + + const v256 __builtin_aes192_decrypt_paired (v256, v256); + XXAES192DECP xxaes192decp {} + + const v256 __builtin_aes256_decrypt_paired (v256, v256); + XXAES256DECP xxaes256decp {} + + const v256 __builtin_aes_genlastkey_paired (v256, const int<2>); + XXAESGENLKP xxaesgenlkp {} + + const v256 __builtin_aes128_genlastkey_paired (v256); + XXAES128GENLKP xxaes128genlkp {} + + const v256 __builtin_aes192_genlastkey_paired (v256); + XXAES192GENLKP xxaes192genlkp {} + + const v256 __builtin_aes256_genlastkey_paired (v256); + XXAES256GENLKP xxaes256genlkp {} + + const vuc __builtin_galois_field_mult (vuc, vuc, const int<1>); + XXGFMUL128 xxgfmul128 {} + + const vuc __builtin_galois_field_mult_gcm (vuc, vuc); + XXGFMUL128GCM xxgfmul128gcm {} + + const vuc __builtin_galois_field_mult_xts (vuc, vuc); + XXGFMUL128XTS xxgfmul128xts {} diff --git a/gcc/doc/extend.texi b/gcc/doc/extend.texi index 7bd84e6d8cc..6ad18fe9073 100644 --- a/gcc/doc/extend.texi +++ b/gcc/doc/extend.texi @@ -26967,6 +26967,8 @@ vector unsigned char); The following additional built-in functions are available for the PowerPC family of processors, starting with Future ISA. +@subsubheading PowerPC Advanced Encryption Standard Assist Built-in Functions + Future ISA of the PowerPC may add new instructions for accelerating AES algorithm.
