2011-10-05PR11061: Make simplifylibcalls fold strcmp("", x) correctly.Eli Friedman
While I'm here, fix the related issue with strncmp, add some actual tests for strcmp and strncmp, and start using StringRef::compare for constant folding instead of using strcmp/strncmp so that the optimized IR isn't dependent on the host's implementation of strcmp. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@141227 91177308-0d34-0410-b5e6-96231b3b80d8
2010-06-16simplify-libcalls: fold strncmp(x, y, 1) -> memcmp(x, y, 1)Benjamin Kramer
The memcmp will be optimized further and even the pathological case 'strstr(x, "x") == x' generates optimal code now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@106097 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-11Change tests from "opt %s" to "opt < %s" so that opt doesn't see theDan Gohman
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
2009-09-08Use opt -S instead of piping bitcode output through llvm-dis.Dan Gohman

2009-09-08Change these tests to feed the assembly files to opt directly, insteadDan Gohman
of using llvm-as, now that opt supports this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81226 91177308-0d34-0410-b5e6-96231b3b80d8
