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. llvm-svn: 81537 2009-09-12 02:01:28 +08:00			`; RUN: opt < %s -globalopt -S \| grep {define void @a}`
If the target of an alias has internal linkage, then the alias can be morphed into the target. Implement this transform, and fix a crash in the existing transform at the same time. llvm-svn: 64583 2009-02-15 17:56:08 +08:00
