2009-10-29make clang emit undefs for padding of structs and unions instead of zeros. ↵Nuno Lopes
this enables constant compaction optimizations. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@85504 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-29Track source information for template arguments and template specializationJohn McCall
types. Preserve it through template instantiation. Preserve it through PCH, although TSTs themselves aren't serializable, so that's pretty much meaningless. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@85500 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-29Extract TemplateArgument into a new header just for common templateJohn McCall
classes. Move its implementation into a new module. This will seem marginally more justified in a bit. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@85499 91177308-0d34-0410-b5e6-96231b3b80d8

2009-10-29Fix accidental use of CheckSVal instead of CheckLocation, and add aTed Kremenek
small test case to show we handle dereferences of undefined values. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@85492 91177308-0d34-0410-b5e6-96231b3b80d8

2009-10-29Fix an insidious bug in RegionStore::RemoveDeadBindings() pointed outTed Kremenek
by Zhongxing Xu. RemoveDeadBindings() would falsely prune SymbolicRegions from the store that wrapped derived symbols whose liveness could only be determined after scanning the store. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@85484 91177308-0d34-0410-b5e6-96231b3b80d8

2009-10-29Move NullDeref and UndefDeref into their own checker. Zhongxing Xu
Add a CheckLocation() interface to Checker. Now ImplicitNullDeref nodes are cached in NullDerefChecker. More cleanups follow. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@85471 91177308-0d34-0410-b5e6-96231b3b80d8

2009-10-29Implement support for semantic checking and template instantiation ofDouglas Gregor
class template partial specializations of member templates. Also, fixes a silly little bug in the marking of "used" template parameters in member templates. Fixes PR5236. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@85447 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-28Implement clang support for indirect branch and address of labelChris Lattner
using the new LLVM support for this. This is temporarily hiding behind horrible and ugly #ifdefs until the time when the optimizer is stable (hopefully a week or so). Until then, lets make it "opt in" :) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@85446 91177308-0d34-0410-b5e6-96231b3b80d8

2009-10-28Remove _clang_initCXLookupHint() and _clang_getCursorWithHint(). Related to ↵Steve Naroff
<rdar://problem/7310688>. Localize the optimization to ResolveLocationInAST(). The last valid AST location is now stored with ASTUnit. There still isn't optimal, however it's an improvement (with a much cleaner API). Having the client manage an "hint" is error prone and complex. I wanted to land the major changes before finishing up the optimizations. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@85425 91177308-0d34-0410-b5e6-96231b3b80d8

2009-10-28Mangle based on the declaration we're given, not the canonicalDouglas Gregor
