Nick Lewycky 4a3935c27e A dead malloc, a free(NULL) and a free(undef) are all trivially dead ... instructions. This doesn't introduce any optimizations we weren't doing before (except potentially due to pass ordering issues), now passes will eliminate them sooner as part of their own cleanups. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142787 91177308-0d34-0410-b5e6-96231b3b80d8		2011-10-24 04:35:36 +00:00

GlobalDCE
GlobalOpt	Refactor code from inlining and globalopt that checks whether a function definition is unused, and enhance it so it can tell that functions which are only used by a blockaddress are in fact dead. This probably doesn't happen much on most code, but the Linux kernel's _THIS_IP_ can trigger this issue with blockaddress. (GlobalDCE can also handle the given tescase, but we only run that at -O3.) Found while looking at PR11180.	2011-10-20 05:23:42 +00:00

SCCP	Make sure IPSCCP never marks a tracked call as overdefined in SCCPSolver::ResolvedUndefsIn. If we do, we can end up in a situation where a function is resolved to return a constant, but the caller is marked overdefined, which confuses the code later.	2011-09-20 23:28:51 +00:00
