2011-07-09Land the long talked about "type system rewrite" patch. ThisChris Lattner
patch brings numerous advantages to LLVM. One way to look at it is through diffstat: 109 files changed, 3005 insertions(+), 5906 deletions(-) Removing almost 3K lines of code is a good thing. Other advantages include: 1. Value::getType() is a simple load that can be CSE'd, not a mutating union-find operation. 2. Types a uniqued and never move once created, defining away PATypeHolder. 3. Structs can be "named" now, and their name is part of the identity that uniques them. This means that the compiler doesn't merge them structurally which makes the IR much less confusing. 4. Now that there is no way to get a cycle in a type graph without a named struct type, "upreferences" go away. 5. Type refinement is completely gone, which should make LTO much MUCH faster in some common cases with C++ code. 6. Types are now generally immutable, so we can use "Type *" instead "const Type *" everywhere. Downsides of this patch are that it removes some functions from the C API, so people using those will have to upgrade to (not yet added) new API. "LLVM 3.0" is the right time to do this. There are still some cleanups pending after this, this patch is large enough as-is. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134829 91177308-0d34-0410-b5e6-96231b3b80d8

2009-05-29Dan noticed that the verifier wasn't thoroughly checking uses ofDuncan Sands

2009-05-22Revert this. There's no way to verifiy indirect calls, and an optimizer can turnTorok Edwin
indirect call into direct call, thus the verifier would reject something it previously accepted. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@72249 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-22Verify that calling conventions match function prototype.Torok Edwin
This only rejects mismatches between target specific calling convention and C/LLVM specific calling convention. There are too many fastcc/C, coldcc/cc42 mismatches in the testsuite, these are not reject by the verifier. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@72248 91177308-0d34-0410-b5e6-96231b3b80d8
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

2008-01-11Do not allow attributes beyond a function's lastDuncan Sands
parameter, even if it is a varargs function. Do allow attributes on the varargs part of a call, but not beyond the last argument. Only allow selected attributes to be on the varargs part of a call (currently only 'byval' is allowed). The reasoning here is that most attributes, eg inreg, simply make no sense here. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45887 91177308-0d34-0410-b5e6-96231b3b80d8
2007-12-21Get the verifier to check attributes on calls as wellDuncan Sands
as on functions. Make it verify invokes and not just ordinary calls. As a (desired) side-effect, it is no longer legal to have call attributes on arguments that are being passed to the varargs part of a varargs function (llvm-as drops them on the floor anyway). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45286 91177308-0d34-0410-b5e6-96231b3b80d8

2007-09-17Fix for PR1633: Verifier doesn't fully verify GC intrinsicsGordon Henriksen
LLVM now enforces the following prototypes for the write barriers: <ty>* @llvm.gcread(<ty2>*, <ty>**) void @llvm.gcwrite(<ty>*, <ty2>*, <ty>**) And for @llvm.gcroot, the first stack slot is verified to be an alloca or a bitcast of an alloca. Fixes test/CodeGen/Generic/GC/lower_gcroot.ll, which violated these. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@42051 91177308-0d34-0410-b5e6-96231b3b80d8
