As far as vABI is supported on x86_64/i?86 only, I am going to enable
mentioned `scan-tree-dump' only
for these targets. This should cure both IA64 and Power.
Concerning attr-simd-3.c. It is known issue: PR68158.
And I believe this test should work everywhere as far as PR is resolved.
I'll put xfail into the test.
Which will lead to (in g++.log):
gcc/testsuite/c-c++-common/attr-simd-3.c:5:48: warning: '__simd__'
attribute does not apply to types\
[-Wattributes]^M
output is:
gcc/testsuite/c-c++-common/attr-simd-3.c:5:48: warning: '__simd__'
attribute does not apply to types\
[-Wattributes]^M
XFAIL: c-c++-common/attr-simd-3.c -std=gnu++98 PR68158 (test for
errors, line 5)
FAIL: c-c++-common/attr-simd-3.c -std=gnu++98 (test for excess errors)
Excess errors:

Patch in the bottom.

* c-c++-common/attr-simd-3.c: Put xfail (PR68158) on dg-error.
This test fails on bare-metal targets that don't support -fcilkplus or
-pthread.
Would you consider moving them to the cilkplus testing directory or
adding an appropriate
effective target check?
I think an effective-target-check is the most appropriate. The whole
point here is to make that attribute independent of Cilk support.
