Hi all,
This patch adds the ARMv8.6 Extension ACLE intrinsics for dot product
operations (vector/by element) to AArch64.
These are:
usdot (vector), <us/su>dot (by element).
The functions are optional from ARMv8.2-a as -march=armv8.2-a+i8mm
and are then enabled by default from ARMv8.6a.
The functions are declared in arm_neon.h, RTL patterns are defined to
generate assembler and tests are added to verify them and perform
adequate checks.
Regression testing on aarch64-none-elf passed successfully.
This patch depends on:
https://gcc.gnu.org/ml/gcc-patches/2019-11/msg02415.html
for Aaarch64 CLI updates, and on:
https://gcc.gnu.org/ml/gcc-patches/2019-12/msg00857.html
for the testsuite effective_target update.
Ok for trunk?
Cheers,
Stam
