clang-p2996/clang/test/SemaOpenACC/sub-array-ast.cpp
Erich Keane c129887817 [OpenACC] Implement SubArray Parsing/Sema (#90796) 
This implementation takes quite a bit from the OMP implementation of
array sections, but only has to enforce the rules as applicable to
OpenACC. Additionally, it does its best to create an AST node (with the
assistance of RecoveryExprs) with as much checking done as soon as
possible in the case of instantiations.
