aarch64: Use memcpy to copy vector tables in vtbl[34] intrinsics
Use __builtin_memcpy to copy vector structures instead of building
a new opaque structure one vector at a time in each of the vtbl[34]
Neon intrinsics in arm_neon.h. This simplifies the header file and
also improves code generation - superfluous move instructions were
emitted for every register extraction/set in this additional
structure.
gcc/ChangeLog:
2021-07-08 Jonathan Wright <jonathan.wright@arm.com>
* config/aarch64/arm_neon.h (vtbl3_s8): Use __builtin_memcpy
instead of constructing __builtin_aarch64_simd_oi one vector
at a time.
(vtbl3_u8): Likewise.
(vtbl3_p8): Likewise.
(vtbl4_s8): Likewise.
(vtbl4_u8): Likewise.
(vtbl4_p8): Likewise.
