openmp: Add support for __has_attribute(omp::directive) and __has_attribute(omp::sequence)
Now that the C++ FE supports these attributes, but not through registering
them in the attributes tables (they work quite differently from other
attributes), this teaches c_common_has_attributes about those.
2021-07-23 Jakub Jelinek <jakub@redhat.com>
* c-lex.c (c_common_has_attribute): Call canonicalize_attr_name also
on attr_id. Return 1 for omp::directive or omp::sequence in C++11
and later.
* c-c++-common/gomp/attrs-1.c: New test.
* c-c++-common/gomp/attrs-2.c: New test.
* c-c++-common/gomp/attrs-3.c: New test.
