David Blaikie c57455683c DebugInfo+DeadArgElimination: Ensure llvm::Function*s from debug info are updated even when DAE removes both varargs and non-varargs arguments on the same function. ... After some stellar (& inspired) help from Reid Kleckner providing a test case for some rather unstable undefined behavior showing up as assertions produced by r214761, I was able to fix this issue in DAE involving the application of both varargs removal, followed by normal argument removal. Indeed I introduced this same bug into ArgumentPromotion (r212128) by copying the code from DAE, and when I fixed the bug in ArgPromo (r213805) and commented in that patch that I didn't need to address the same issue in DAE because it was a single pass. Turns out it's two pass, one for the varargs and one for the normal arguments, so the same fix is needed (at least during varargs removal). So here it is. (the observable/net effect of this bug, even when it didn't result in assertion failure, is that debug info would describe the DAE'd function in the abstract, but wouldn't provide high/low_pc, variable locations, line table, etc (it would appear as though the function had been entirely optimized away), see the original PR14016 for details of the general problem) I'm not recommitting the assertion just yet, as there's been another regression of it since I last tried. It might just be a few test cases weren't adequately updated after Adrian or Duncan's recent schema changes. llvm-svn: 219210		2014-10-07 15:10:23 +00:00
