aarch64: Pass and return Neon vector-tuple types without a parallel
Neon vector-tuple types can be passed in registers on function call
and return - there is no need to generate a parallel rtx. This patch
adds cases to detect vector-tuple modes and generates an appropriate
register rtx.
This change greatly improves code generated when passing Neon vector-
tuple types between functions; many new test cases are added to
defend these improvements.
gcc/ChangeLog:
2021-10-07 Jonathan Wright <jonathan.wright@arm.com>
* config/aarch64/aarch64.c (aarch64_function_value): Generate
a register rtx for Neon vector-tuple modes.
(aarch64_layout_arg): Likewise.
gcc/testsuite/ChangeLog:
* gcc.target/aarch64/vector_structure_intrinsics.c: New code
generation tests.
