The C++ FE doesn't set the expr_location of the split acc loop in combined acc
parallel/kernels loop directives. This only happens for with combined
directives, otherwise cp_parser_omp_construct would be responsible for setting
the location. After fixing this bug, I was able to resolve a couple of long
standing diagnostics discrepancies between the C/C++ FEs in the test suite.
gcc/cp/
* parser.c (cp_parser_oacc_kernels_parallel): Adjust EXPR_LOCATION
on the combined acc loop.
gcc/testsuite/
* c-c++-common/goacc/combined-directives-3.c: New test.
* c-c++-common/goacc/loop-2-kernels.c (void K): Adjust test.
* c-c++-common/goacc/loop-2-parallel.c (void P): Adjust test.
* c-c++-common/goacc/loop-3.c (void p2): Adjust test.
