X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=f348846e25573bc1f62f5a26317c331ad8dce041;p=gcc.git [GCC][PATCH][ARM]Add ACLE intrinsics for dot product (vusdot - vector, vdot - by element) for AArch32 AdvSIMD ARMv8.6 Extension This patch adds the ARMv8.6 Extension ACLE intrinsics for dot product operations (vector/by element) to the ARM back-end. These are: usdot (vector), dot (by element). The functions are optional from ARMv8.2-a as -march=armv8.2-a+i8mm and for ARM they remain optional after as of ARMv8.6-a. The functions are declared in arm_neon.h, RTL patterns are defined to generate assembler and tests are added to verify and perform adequate checks. Regression testing on arm-none-eabi passed successfully. gcc/ChangeLog: 2020-02-11 Stam Markianos-Wright * config/arm/arm-builtins.c (enum arm_type_qualifiers): (USTERNOP_QUALIFIERS): New define.
