aarch64: Allow compiler to define ls64 builtins [PR110132]
This patch refactors the ls64 builtins to allow the compiler to define them
directly instead of having wrapper functions in arm_acle.h. This should be not
only easier to maintain, but it makes two important correctness fixes:
- It fixes PR110132, where the builtins ended up getting declared with
invisible bindings in the C FE, so the FE ended up synthesizing
incompatible implicit definitions for these builtins.
- It allows the builtins to be used with LTO, which didn't work previously.
We also take the opportunity to add test coverage from C++ for these
builtins.
gcc/ChangeLog:
PR target/110132
* config/aarch64/aarch64-builtins.cc (aarch64_general_simulate_builtin):
New. Use it ...
(aarch64_init_ls64_builtins): ... here. Switch to declaring public ACLE
names for builtins.
(aarch64_general_init_builtins): Ensure we invoke the arm_acle.h
setup if in_lto_p, just like we do for SVE.
* config/aarch64/arm_acle.h: (__arm_ld64b): Delete.
(__arm_st64b): Delete.
(__arm_st64bv): Delete.
(__arm_st64bv0): Delete.
gcc/testsuite/ChangeLog:
PR target/110132
* lib/target-supports.exp (check_effective_target_aarch64_asm_FUNC_ok):
Extend to ls64.
* g++.target/aarch64/acle/acle.exp: New.
* g++.target/aarch64/acle/ls64.C: New test.
* g++.target/aarch64/acle/ls64_lto.C: New test.
* gcc.target/aarch64/acle/ls64_lto.c: New test.
* gcc.target/aarch64/acle/pr110132.c: New test.
