[PATCH 1/7] aarch64: Allow 64-bit vector modes in pattern for BCAX instruction

2025-07-07 Thread Kyrylo Tkachov
Hi all, The BCAX instruction from TARGET_SHA3 only operates on the full .16b form of the inputs but as it's a pure bitwise operation we can use it for the 64-bit modes as well as there we don't care about the upper 64 bits. This patch extends the relevant pattern in aarch64-simd.md to accept the 6
