2009-12-03Do not include the 'this' pointer adjustment in the covariant return type. ↵Anders Carlsson
Instead, store it in the (now oddly named) Thunks map. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@90386 91177308-0d34-0410-b5e6-96231b3b80d8

2009-12-03Add 'has_feature(cxx_exceptions)' to allow code to determine via ↵Ted Kremenek
preprocessor logic if C++ exceptions are enabled. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@90378 91177308-0d34-0410-b5e6-96231b3b80d8

2009-12-03Add "has_feature" support for C++ RTTI.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@90368 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-03Stop stripping UnresolvedUsingDecls out of LookupResults that have otherJohn McCall
results in them (which we were doing intentionally as a stopgap). Fix an DeclContext lookup-table ordering problem which was causing UsingDecls to show up incorrectly when looking for ordinary results. And oh hey Clang-Code-Syntax passes now. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@90367 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-03Add a heuristic to the dead stores checker to prune dead stores for ↵Ted Kremenek
variables annotated with '__block'. This is overly conservative, but now the analyzer doesn't report dead stores for variables that can be updated by a block call. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@90364 91177308-0d34-0410-b5e6-96231b3b80d8

2009-12-02Cleanups on exceptional edges don't work at all, yet. This doesn'tMike Stump
catch very many of them and if we caught all of them, the errors would be annoying. I'm working on this next. WIP. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@90358 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@90357 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-02Add missing branch to exit. Seemingly obvious when I look at theMike Stump
code, but to track this down was laborious. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@90356 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-02Improve source location information for C++ member initializers in aDouglas Gregor
constructor, by keeping the DeclaratorInfo* rather than just the type and a single location. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@90355 91177308-0d34-0410-b5e6-96231b3b80d8

2009-12-02Fix for PR5522 and PR5666: fix a bunch of mangling issues with extern variablesEli Friedman
and funcctions declared locally within a function. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@90344 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-02Use a more rigorous definition of 'class member'. I don't have any evidenceJohn McCall
that this was causing a problem, but it could have. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@90343 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-02Recognize that EnumConstantDecls can be found by lookup and are not instanceJohn McCall
members. Fixes PR5667. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@90341 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-02Pull the terminate handler up so that we can use it for the catchMike Stump
parameter setup code and set up the catch parameter setup code to protect that code with terminate. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@90340 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@90330 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-02Extend -remap-file=from;to to permit mapping from a non-existentDouglas Gregor
file. This is accomplished by introducing the notion of a "virtual" file into the file manager, which provides a FileEntry* for a named file whose size and modification time are known but which may not exist on disk. Added a cute little test that remaps both a .c file and a .h file it includes to alternative files. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@90329 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-02In Sema, whenever we think that a function is going to cause a vtable to be ↵Anders Carlsson
generated, we mark any virtual implicit member functions as referenced. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@90327 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@90322 91177308-0d34-0410-b5e6-96231b3b80d8

2009-12-02Fix ASTUnit::getOriginalSourceFileName() when using ASTUnit's derived fromDaniel Dunbar
source files. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@90311 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-02ASTUnit: Don't create an LLVMContext, it shouldn't be needed.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@90310 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-02Rip out the last remaining implicit use of OverloadedFunctionDecl in Sema:John McCall
LookupResult::getAsSingleDecl() is no more. Shift Sema::LookupSingleName to return null on overloaded results. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@90309 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-02terminate doesn't throw.Mike Stump
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@90308 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-02Introduce a new clang-cc option Douglas Gregor
-remap-file=from;to which takes the file "from" and transparently replaces its contents with the contents of the file "to" from the source manager's perspective. This is the moral equivalent of cp from saved cp to from <call clang> cp saved from rm saved without all of the pesky file copying. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@90307 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-02Push overloaded function templates through the parser using a totally differentJohn McCall
leaked data structure than before. This kills off the last remaining explicit uses of OverloadedFunctionDecl in Sema. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@90306 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-02More exception handling improvements... WIP.Mike Stump
Highlights include: Add a helper to generate __cxa_free_exception and _ZSt9terminatev. Add a region to handle EH object deallocation for ctor failures for throw. Add a terminate handler for __cxa_end_catch. A framework for adding cleanup actions for the exceptional edges only. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@90305 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-02Fix another "operator delete missing" crash: make sure we don't checkEli Friedman
isVirtual() before we've actually calculated whether the destructor is virtual. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@90303 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-02Make sure to call AddOverriddenMethods for implicit copy assignment operators;Eli Friedman
it's rare, but possible, for the difference to be significant. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@90301 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-02Extend the source manager with the ability to override the contents ofDouglas Gregor
files with the contents of an arbitrary memory buffer. Use this new functionality to drastically clean up the way in which we handle file truncation for code-completion: all of the truncation/completion logic is now encapsulated in the preprocessor where it belongs (<rdar://problem/7434737>). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@90300 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-02Hard bifurcate the state into nil receiver and non-nil receiver, so thatZhongxing Xu
we don't need to use the DoneEvaluation hack when check for ObjCMessageExpr. PreVisitObjCMessageExpr() only checks for undefined receiver or arguments. Add checker interface EvalNilReceiver(). This is a 'once-and-done' interface. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@90296 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-02Eliminate the unnecessary FirstFID cache variable from the source manager's ↵Douglas Gregor
ContentCache git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@90294 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-02Stop trying to analyze class-hierarchies for dependently-scoped id-expressions;John McCall
there's nothing interesting we can say now that we're correctly not requiring the qualifier to name a known base class in dependent contexts. Require scope specifiers on member access expressions to name complete types if they're not dependent; delay lookup when they are dependent. Use more appropriate diagnostics when qualified implicit member access expressions find declarations from unrelated classes. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@90289 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-02Add ASTUnit::LoadFromCommandLine, which creates an ASTUnit out of a list ofDaniel Dunbar
(clang/driver) command line arguments (including the source file). - The arguments are expected to include the source file. - The idea is that even though this is a somewhat odd API, its the form which many tools can most easily use (for example, by interposing with the compiler). Also, switch index-test's -ast-from-source to use this entry point, and provide a -arg command line argument which can be used to test that the command line arguments are handled correctly. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@90288 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-02Driver: Add Command::Creator member variable, which tracks the tool that wasDaniel Dunbar
used to create a particular command. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@90287 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-01Added an assert.Fariborz Jahanian
