David Blaikie efae14e96c Fix tests to be more robust (to older versions of grep, lesser lit-like test runners, etc) ... Seems I had a problem with my version of grep, when run by lit, not supporting the \s escape. This seems to fix it for me & I'll be getting the buildbots to run these tests too to keep an eye on them (actually loop-convert tests still fail when run via a make build, so that'll be addressed in a future commit). I could use [[:space:]] to generalize over other whitespace but that seemed unnecessarily verbose when the flexibility wasn't actually required by the current text of the tests. Also I just simplified a lot of the loop-convert tests (removing the unecessary temp file deletion at the start, removing the unnecessary && for FileCheck, etc). The remove-cstr-calls/basic.cpp changes were necessitated by an out of tree lit-like test runner that's a bit less fantastic about escaping. They were modeled on existing tooling test cases in Clang, with thanks to Manuel Klimek for the pointers. llvm-svn: 163009		2012-08-31 17:49:33 +00:00
