aarch64: Implement ACLE Data Intrinsics
This patch adds support for the ACLE Data Intrinsics to the AArch64 port.
gcc/ChangeLog:
2022-07-25 Andre Vieira <andre.simoesdiasvieira@arm.com>
* config/aarch64/aarch64.md (rbit<mode>2): Rename this ...
(@aarch64_rbit<mode>): ... to this and change it in...
(ffs<mode>2,ctz<mode>2): ... here.
(@aarch64_rev16<mode>): New.
* config/aarch64/aarch64-builtins.cc: (aarch64_builtins):
Define the following enum AARCH64_REV16, AARCH64_REV16L,
AARCH64_REV16LL, AARCH64_RBIT, AARCH64_RBITL, AARCH64_RBITLL.
(aarch64_init_data_intrinsics): New.
(aarch64_general_init_builtins): Add call to
aarch64_init_data_intrinsics.
(aarch64_expand_builtin_data_intrinsic): New.
(aarch64_general_expand_builtin): Add call to
aarch64_expand_builtin_data_intrinsic.
* config/aarch64/arm_acle.h (__clz, __clzl, __clzll, __cls, __clsl,
__clsll, __rbit, __rbitl, __rbitll, __rev, __revl, __revll, __rev16,
__rev16l, __rev16ll, __ror, __rorl, __rorll, __revsh): New.
gcc/testsuite/ChangeLog:
