Chris Lattner 5b222d748a Implement more aggressive support for analyzing string length. This ... generalizes the previous code to handle the case when the string is not an immediate to the strlen call (for example, crazy stuff like strlen(c ? "foo" : "bart"+1) -> 3). This implements gcc.c-torture/execute/builtins/strlen-2.c. I will generalize other cases in simplifylibcalls to use the same routine later. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@50408 91177308-0d34-0410-b5e6-96231b3b80d8		2008-04-29 06:56:02 +00:00
