From 65dd610dcbcf5e1a952f341d0a441593bebe200f Mon Sep 17 00:00:00 2001 From: Kyrylo Tkachov Date: Thu, 7 Nov 2019 10:49:06 +0000 Subject: [PATCH] [arm][5/X] Implement Q-bit-setting SIMD32 intrinsics This patch implements some more Q-setting intrinsics of the multiply-accumulate variety, but these are in the SIMD32 family in that they treat their operands as packed SIMD values, but that's not important at the RTL level. * config/arm/arm.md (arm__insn): New define_insns. (arm_): New define_expands. * config/arm/arm_acle.h (__smlad, __smladx, __smlsd, __smlsdx, __smuad, __smuadx): Define. * config/arm/arm_acle_builtins.def: Define builtins for the above. * config/arm/iterators.md (SIMD32_TERNOP_Q): New int_iterator. (SIMD32_BINOP_Q): Likewise. (simd32_op): Handle the above. * config/arm/unspecs.md: Define unspecs for the above. * gcc.target/arm/acle/simd32.c: Update test.
