candidates. Thanks to Chris for the review! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59260 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-13Fix an obscure rewriter bug when rewriting implementations that don't have a ↵Steve Naroff
corresponding interface (found while doing random testing on another bug). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59259 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-13Fix a couple of suboptimalities in error recovery.Chris Lattner
1. In the top level of ParseStatementOrDeclaration, don't eat a } if we just parsed a statement if it list there. Also, don't even bother emitting an error about a missing semicolon if the statement had a bug (an rbrace is fine). 2. In do/while parsing, don't require a 'while' to be present if the do body didn't parse. This allows us to generate a clean diagnostic for this code: t.c:1:22: error: expected expression void foo (void) { do . while (0); } ^ Thanks to Neil for pointing this out. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59256 91177308-0d34-0410-b5e6-96231b3b80d8

2008-11-13Using llvm::OwningPtr<> for CurLexer and CurTokenLexer. This makes both the ↵Ted Kremenek
ownership semantics of these objects explicit within the Preprocessor and also tightens up the code (explicit deletes not needed). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59249 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-13Use PushIncludeMacroStack/PopMacroStack instead of manually pushing/popping ↵Ted Kremenek
from IncludeMacroStack. This is both cleaner and makes the include stack transparently extensible. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59248 91177308-0d34-0410-b5e6-96231b3b80d8

it to be evaluated by APSInt::operators. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59238 91177308-0d34-0410-b5e6-96231b3b80d8

2008-11-13Lift the pointer to alloca'ed region to the pointer to its first element.Zhongxing Xu
This is required by some operations, e.g., *p = 1; p[0] = 1;. Also set the AllocaRegion's type during the cast. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59232 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-13Change AllocaRegion to subclass TypedRegion. We need to know ElementRegion'sZhongxing Xu
type when assigning to it. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59229 91177308-0d34-0410-b5e6-96231b3b80d8

2008-11-13GRExprEngine/CFRefCount/GRSimpleVals: We don't do any special handling (yet) ↵Ted Kremenek
of vector types. Add explicit checks that when we process integers that they really are scalars. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59225 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-13Fix for crash issues with comma operators with a void first operand, and Eli Friedman
some more bullet-proofing/enhancements for tryEvaluate. This shouldn't cause any behavior changes except for handling cases where we were crashing before and being able to evaluate a few more cases in tryEvaluate. This should settle the minor mess surrounding r59196. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59224 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-13Obey the FIXMES!Daniel Dunbar
- Resume running the always inliner pass always now that LLVM has been improved and functions with debug info can be inlined. - Remove unused header. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59223 91177308-0d34-0410-b5e6-96231b3b80d8

2008-11-13[LLVM up] Update for raw_fd_ostream change. This fixes a FIXME thatDaniel Dunbar
the Backend output should be done in binary mode. - I'd appreciate it if someone who has a Windows build could verify this. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59221 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-13GRExprEngine::VisitInitListExpr:Ted Kremenek
- Don't crash on vector types. - Handle typedefs. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59220 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-13Easy IRgen improvement for bitfields, don't emit x >> 0.Daniel Dunbar
- Logic such as this quite possibly should be optional builder behavior. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59213 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-13Backout of r59196, plus a new ICE test. Sorry if this is a Eli Friedman
little rude; I figure it's cleaner to just back this out now so it doesn't get forgotten or mixed up with other checkins. The modification to isICE is simply wrong; I've added a test that the change to isICE breaks. I'm pretty sure the modification to tryEvaluate is also wrong. At the very least, there's some serious miscommunication going on here, as this is going in exactly the opposite direction of r59105. My understanding is that tryEvaluate is not supposed to care about side effects. That said, a lot of the clients to tryEvaluate are expecting it to enforce a no-side-effects policy, so we probably need another method that provides that guarantee. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59212 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-13Supply finished flag to EmitBlock for common statements which useDaniel Dunbar
landing pads. - Primarily a cleanliness issue instead of a performance issue (this eliminates all blocks w/o predecessors on 176.gcc/expr.c), but this also allows subsequent code to recognize it is unreachable and potentially avoid IRgen. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59211 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-13Normalize many BasicBlock names.Daniel Dunbar
- Use dotted notation for blocks related to a particular statement type. - Use .end for landing pads. No functionality change in NDEBUG mode. :) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59210 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-13Revert to older checker build.Ted Kremenek

2008-11-13Add IsFinished arg to EmitBlock.Daniel Dunbar
- Indicates that caller is done with the block and it can be dropped if it has no predecessors. Useful for callers who need to make landing pads but which may not be reached. No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59207 91177308-0d34-0410-b5e6-96231b3b80d8

2008-11-13For if blocks with no else, name the join block ifend instead of theDaniel Dunbar
more confusing ifelse. Use dotted names for if blocks (if.then vs ifthen). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59201 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-13Fix bug where the body block of an ObjCForCollectionStmt would not properly ↵Ted Kremenek
get expanded as a series of basic blocks. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59197 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-13Fix bug in constant evaluation exposed by 176.gcc.Daniel Dunbar
- Evaluation of , operator used bogus assumption that LHS could be evaluated as an integral expression even though its type is unspecified. This change is making isICE very permissive of the LHS in non-evaluated contexts because it is not clear what predicate we would use to reject code here. The standard didn't offer me any guidance; opinions? git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59196 91177308-0d34-0410-b5e6-96231b3b80d8

2008-11-12Don't build identifiers for C++ constructors, destructors, orDouglas Gregor
conversion functions. Instead, we just use a placeholder identifier for these (e.g., "<constructor>") and override NamedDecl::getName() to provide a human-readable name. This is one potential solution to the problem; another solution would be to replace the use of IdentifierInfo* in NamedDecl with a different class that deals with identifiers better. I'm also prototyping that to see how it compares, but this commit is better than what we had previously. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59193 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59187 91177308-0d34-0410-b5e6-96231b3b80d8

2008-11-12Move LexIncludeFilename from Lexer to PreprocessorLexer.Ted Kremenek
PreprocessorLexer now has a virtual method "IndirectLex" which allows it to call the lex method of its subclasses. This is not for performance intensive operations. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59185 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-12Quick fix for crash in IRgen when we can tryEvaluate a condition toDaniel Dunbar
something that is not an int. - Ignore these cases for now, added FIXME that we should also boolize them. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59184 91177308-0d34-0410-b5e6-96231b3b80d8
