Roman Lebedev eae3e5a494 [Reduce] Argument reduction: do deal with function declarations ... We can happily turn function definitions into declarations, thus obscuring their argument from being elided by this pass. I don't believe there is a good reason to just ignore declarations. likely even proper llvm intrinsics ones, at worst the input becomes uninteresting. The other question here is that all these transforms are all-or-nothing. In some cases, should we be treating each use separately? The main blocker here seemed to be that llvm::CloneFunctionInto() does `&OldFunc->front()`, which inserts a nullptr into a densemap, which is not happy about it and asserts.		2020-07-26 01:31:56 +03:00
