aarch64: Use RTL builtins for [su]mull_high_n intrinsics
Rewrite [su]mull_high_n Neon intrinsics to use RTL builtins rather
than inline assembly code, allowing for better scheduling and
optimization.
gcc/ChangeLog:
2021-02-03 Jonathan Wright <jonathan.wright@arm.com>
* config/aarch64/aarch64-simd-builtins.def: Add [su]mull_hi_n
builtin generator macros.
* config/aarch64/aarch64-simd.md
(aarch64_<su>mull_hi_n<mode>_insn): Define.
(aarch64_<su>mull_hi_n<mode>): Define.
* config/aarch64/arm_neon.h (vmull_high_n_s16): Use RTL builtin
instead of inline asm.
(vmull_high_n_s32): Likewise.
(vmull_high_n_u16): Likewise.
(vmull_high_n_u32): Likewise.
