I wanted to assign a new pragma for loops in clang. Let’s call it “#pragma XXX” which can be applied to any loop in the entire loop hierarchy. I added the support for my pragma by following the same steps as were being used in the default implementation of “unroll” pragma.
But now, when I compile any program using clang to llvm IR it attaches the pragma related metadata to the loop as well as to all the loops nested inside it. I just want to add the metadata to that particular loop and not all the loops nested inside it. Can someone suggest what would be the right way of doing this? or rather what files should I look into.
So far I have made changes in the following files:
Any help would be appreciated.
