2009-01-02Reimplement the old and horrible bison parser for .ll files with a niceChris Lattner
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

2008-12-15It turns out that "align 1" and unaligned are different. Add a bias to theNick Lewycky
alignment attribute such that 0 means unaligned. This will probably require a rebuild of llvm-gcc because of the change to Attributes.h. If you see many test failures on "make check", please rebuild your llvm-gcc. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@61030 91177308-0d34-0410-b5e6-96231b3b80d8
2008-12-15Introducing nocapture, a parameter attribute for pointers to indicate that theNick Lewycky
callee will not introduce any new aliases of that pointer. The attributes had all bits allocated already, so I decided to collapse alignment. Alignment was previously stored as a 16-bit integer from bits 16 to 32 of the attribute, but it was required to be a power of 2. Now it's stored in log2 encoded form in five bits from 16 to 21. That gives us 11 more bits of space. You may have already noticed that you only need four bits to encode a 16-bit power of two, so why five bits? Because the AsmParser accepted 32-bit alignments, even though we couldn't store them (they were silently discarded). Now we can store them in memory, but not in the bitcode. The bitcode format was already storing these as 64-bit VBR integers. So, the bitcode format stays the same, keeping the alignment values stored as 16 bit raw values. There's some hideous code in the reader and writer that deals with this, waiting to be ripped out the moment we run out of bits again and have to replace the parameter attributes table encoding. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@61019 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-24Extend the 'noalias' attribute to function return values. This is intended toNick Lewycky
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
