Hi,
I've committed attached patch, which adds testcases that test the
-Wuninitialized warning for the if clause on various openacc directives.
I found an issue with line-numbers of the warning in C++, which I've
filed as PR70392 - '[openacc] inconsistent line numbers in uninitialised
warnings for if clause'.
Some of the warning scans are xfailed in C++ due to that PR.
Thanks,
- Tom
