clang-p2996/clang/test/AST/ast-print-openacc-loop-construct.cpp
erichkeane 0b0b153094 [OpenACC] Implement 'reduction' Sema on 'loop' construct 
The reduction clause has some minor restrictions on the variable
references that are implementable, so this implements those.  Others
require reachability analysis, so this patch documents that we're not
going to do that in the CFE(or at least save it for the MLIR passes).
