Peter Steinfeld c757418869 [flang] Failed call to CHECK() for call to ASSOCIATED(NULL()) ... Calling "ASSOCATED(NULL()) was causing an internal check of the compiler to fail. I fixed this by changing the entry for "ASSOCIATED" in the intrinsics table to accept "AnyPointer" which contains a new "KindCode" of "pointerType". I also changed the function "FromActual()" to return a typeless intrinsic when called on a pointer, which duplicates its behavior for BOZ literals. This required changing the analysis of procedure arguments. While testing processing for procedure arguments, I found another bad call to `CHECK()` which I fixed. I made several other changes: -- I implemented constant folding for ASSOCIATED(). -- I fixed handling of NULL() in relational operations. -- I implemented semantic analysis for ASSOCIATED(). -- I noticed that the semantics for ASSOCIATED() are similar to those for pointer assignment. So I extracted the code that pointer assignment uses for procedure pointer compatibility to a place where it could be used by the semantic analysis for ASSOCIATED(). -- I couldn't figure out how to make the general semantic analysis for procedure arguments work with ASSOCIATED()'s second argument, which can be either a pointer or a target. So I stopped using normal semantic analysis for arguments for ASSOCIATED(). -- I added tests for all of this. Differential Revision: https://reviews.llvm.org/D88313		2020-10-16 07:12:57 -07:00
