Change tests from "opt %s" to "opt < %s" so that opt doesn't see the input filename so that opt doesn't print the input filename in the output so that grep lines in the tests don't unintentionally match strings in the input filename. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81537 91177308-0d34-0410-b5e6-96231b3b80d8 2009-09-11 18:01:28 +00:00			`; RUN: opt < %s -aa-eval \|& grep {1 no alias response}`
Extend the 'noalias' attribute to function return values. This is intended to indicate functions that allocate, such as operator new, or list::insert. The actual definition is slightly less strict (for now). No changes to the bitcode reader/writer, asm printer or verifier were needed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@59934 91177308-0d34-0410-b5e6-96231b3b80d8 2008-11-24 03:41:24 +00:00
