2010-11-15Remove invalid assertion from CFG builder. When building the CFG pieces for ↵Ted Kremenek
a ternary '?' expression, it is possible for the confluence block to only have a single predecessor due to calls to 'noreturn' functions. Fixes assertion failure reported in PR 8619. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@119284 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-15Relax assertion in SValuator so that we don't crash when analyzing a call ↵Ted Kremenek

2010-11-15Implement C++0x [temp.func.order]p3 (aka DR532) properly. InDouglas Gregor
particular, we only add the implement object parameter type if only one of the function templates is a non-static member function template. Moreover, since this DR differs from existing practice in C++98/03, this commit implements the existing practice (which ignores the first parameter of the function template that is not the non-static member function template) in C++98/03 mode. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@119145 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-15Clean up some names and fix the handling of default sysroots on Windows andChandler Carruth
other platforms where the textual default of '/' isn't the system's root directory. We should probably still make the textual default platform specific, but this should avoid the particularly bad problem with the previous state: we applied a sysroot of '/' to '/usr/local/google' which added '//usr/local/include' to the windows header search path, a share on another machine named 'usr'. Oops. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@119131 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-14Revert r118991.Zhongxing Xu
Elidable CXXConstructExpr should inhibit calling destructor for temporary that is copied, not the one created. This is because eliding copy constructor means that the object that was to be copied will be constructed directly in memory the copy would be constructed in. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@119044 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-14Always emit full loads from volatile complex l-values.John McCall
Return the result of a complex assignment with the original values, not by performing a load from the l-value; this is the correct semantics in C, although not in C++. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@119037 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-14Add a few more complex-related cast kinds that arise due to arbitraryJohn McCall
implicit conversions; the last batch was specific to promotions. I think this is the full set we need. I do think dividing the cast kinds into floating and integral is probably a good idea. Annotate a *lot* more C casts with useful cast kinds. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@119036 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-13When we're type-checking the result of calling a conversion functionDouglas Gregor
(while computing user conversion sequences), make sure that a result of class type is a complete class type. Had we gone through ActOnCallExpr, this would have happened when we built the CallExpr.

2010-11-13Add GRWorkList::VisitItemsInWorkList() to allow a client to introspect the ↵Ted Kremenek
contents of a worklist. This API required changing the BFS worklist to use a deque instead of a queue, but that is better for performance reasons anyway. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@118982 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-12Replace one hack with a different hack: strip out the ObjectTypeJohn McCall

2010-11-11RegionStore/BasicStore: do not return UndefinedVal for accesses to concrete ↵Ted Kremenek
