Benjamin Kramer bbb006ad7d SimplifyCFG: Enhance the "remove CFG edge that leads to null pointer dereference" optimization to also handle instructions with multiple uses. ... We conservatively only check the first use to avoid walking long use chains. This catches the common case of having both a load and a store to a pointer supplied by a PHI node. llvm-svn: 165232		2012-10-04 16:11:49 +00:00
