Make tests which first provide a negative assertion via 'not', then a pipeline, and then a positive assertion via grep, use two RUN lines instead. Supporting these complex ideas of 'success' and 'failure' across multiple stages of a pipeline is brittle in the shell world, and would block switching to ShTest format; it only worked due to contrivances introduced by the TclTest format. Writing this as two separate RUN lines seems clearer in any event. This is another step toward completely removing TclTests from lit. llvm-svn: 159524 2012-07-02 20:23:19 +08:00			`; RUN: not llvm-as < %s > /dev/null 2> %t`

Reimplement the old and horrible bison parser for .ll files with a nice and clean recursive descent parser. This change has a couple of ramifications: 1. The parser code is about 400 lines shorter (in what we maintain, not including what is autogenerated). 2. The code should be significantly faster than the old code because we don't have to work around bison's poor handling of datatypes with ctors/dtors. This also makes the code much more resistant to memory leaks. 3. We now get caret diagnostics from the .ll parser, woo. 4. The actual diagnostics emited from the parser are completely different so a bunch of testcases had to be updated. 5. I now disallow "%ty = type opaque %ty = type i32". There was no good reason to support this, it was just an accident of the old implementation. I have no reason to think that anyone is actually using this. 6. The syntax for sticking a global variable has changed to make it unambiguous. I don't think anyone is depending on this since only clang supports this and it is not solid yet, so I'm not worried about anything breaking. 7. This gets rid of the last use of bison, and along with it the .cvs files. I'll prune this from the makefiles as a subsequent commit. There are a few minor cleanups that can be done after this commit (suggestions welcome!) but this passes dejagnu testing and is ready for its time in the limelight. llvm-svn: 61558 2009-01-02 15:01:27 +08:00			`@anInt = global i32 1`
