[RFC][LLVM] New Constant type for representing function PLT entries
I do have concerns about the amount of object level modeling that we want to do in the IR though. While it isn't the highest level IR we've managed to mostly avoid these kinds of features/complications in the past. I'm definitely interested in hearing some alternate implementations here and there rather than a full set of constants for relocations. Keeping the IR abstract enough over

[RFC][LLVM] New Constant type for representing function PLT entries
Hi all, We would like to propose a new Constant type in LLVM for representing entries in the Procedure Linkage Table (PLT). The PLT is a data structure used for dispatching position-independent function calls to appropriate functions where the address of the function is not known statically. Right now, if a call is made to a function, it may be lowered to a direct call to the function itself or
