Chris Lattner 78f7a25f98 prevent jump threading from merging blocks when their address is ... taken (and used!). This prevents merging the blocks (invalidating the block addresses) in a case like this: #define _THIS_IP_ ({ __label__ __here; __here: (unsigned long)&&__here; }) void foo() { printf("%p\n", _THIS_IP_); printf("%p\n", _THIS_IP_); printf("%p\n", _THIS_IP_); } which fixes PR4151. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@125829 91177308-0d34-0410-b5e6-96231b3b80d8		2011-02-18 04:43:06 +00:00
