Hi all,
I've thought about this check a bit more and I think we can compactly
auto-generate checks
for any aarch64 architecture extension support in the assembler.
This is done in a similar way we autogenerate the arm_arch_*_ok checks
for arm.
So in this revision we autogenerate aarch64_asm_<ext>_ok checks for
every architecture extension
using some of the expect machinery. This should make this approach a bit
more general to handle
checks for any .arch_extension argument without much extra cost.
This still assumes that the assembler supports the .arch_extension
pseudo-op, the effective
target check will fail if it doesn't. This is what we want for this
testcase.
Is this patch ok instead of
https://gcc.gnu.org/ml/gcc-patches/2016-02/msg01052.html ?
Thanks,
Kyrill

* lib/target-supports.exp: Define aarch64_asm_FUNC_ok checks
for fp, simd, crypto, crc, lse.
* doc/sourcebuild.texi (AArch64-specific attributes): Document the
above.
* gcc.target/aarch64/assembler_arch_1.c: Add aarch64_asm_lse_ok
effective target check.
