[PATCH] D40249: Copy Function's calling convention by default when creating a new Call

[Reid Kleckner via Phabricator via llvm-commits]

rnk added a comment.

This wasn't what I had in mind. When a frontend (or any other IR generator) creates a call, it should have a source of type information telling it the function prototype and the calling convention (in clang, the AST). It should also apply any other wacky calling convention flags like -mregparm and other things. In the special case where the frontend is emitting a call to a function defined in the current TU, we should have a check that the conventions match. I was imagining that you'd make IRBuilder implement that assert, and then add an alternative CreateCallWithConvention entry point or something like that to allow the frontend to override the check.
