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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@61558 91177308-0d34-0410-b5e6-96231b3b80d8

add testcase for type parsing.

Extend the 'noalias' attribute to function return values. This is intended to

2008-11-24T03:41:24Z

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

supported. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53427 91177308-0d34-0410-b5e6-96231b3b80d8

Fix some escaping and quoting in RUN lines, mainly involving { and <. In two

cases quoting of <{ didn't work out, so I changed the grep to check for }> instead. This fixes 7 testcases that were not properly running before. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52182 91177308-0d34-0410-b5e6-96231b3b80d8

Remove lingering references to .llx and .tr in the tests.

Eliminate questionable syntax for stdin redirection. This probably also speeds things up a bit.

sabre brings to my attention that the 'tr' suffix is also obsolete

Rename the last test with .llx extension to .ll, resolve duplicate test by renaming to isnan2. Now that no test has llx ending there is no need to search for them from dg.exp too.
