Hi Alan,
In my cross-testing I've noticed that your new test:
gcc.target/aarch64/simd/int_comparisons_1.c scan-assembler-not not
is PASS for targets aarch64-none-elf and aarch64_be-none-elf, but
FAIL for aarch64-none-linux-gnu.
It seems this is not what you saw in your own validations?
Hmmm, thanks for the heads-up. Now reproduced. Looks like a TCL regexp issue,
should have a fix shortly.
Cheers,
--Alan

* config/aarch64/aarch64-protos.h
Vector comparisons are sometimes generated with needless 'not' instructions, and
'cmtst' is generally not output at all. This patch makes
gen_aarch64_vcond_internal more intelligent with regard to swapping the operands
to both the comparison and the conditional move, such that not is avoided
