OpenMP: Document ompx warnings + add Fortran omx warning [PR106670]
omp/ompx sentinels are for vendor extensions; as they might be required for
the correctness of the program, a warning should be printable. This patch
documents in the OpenMP 5.2 table the existing warnings, including the new
warning for for fixed source form Fortran.
PR fortran/106670
gcc/fortran/ChangeLog:
* scanner.cc (skip_fixed_omp_sentinel): Add -Wsurprising warning
for 'omx' sentinels with -fopenmp.
* invoke.texi (-Wsurprising): Document additional warning case.
