2012-02-16[analyzer] Diagnostics: Ensure that the default end of diagnostic pathAnna Zaks
piece can always be generated. The default end of diagnostic path piece was failing to generate on a BlockEdge that was outgoing from a basic block without a terminator, resulting in a very simple diagnostic being rendered (ex: no path highlighting or custom visitors). Reuse another function, which is essentially doing the same thing and correct it not to fail when a block has no terminator. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@150659 91177308-0d34-0410-b5e6-96231b3b80d8
2012-02-16[analyzer] Malloc Checker: Give up when a pointer escapes into a struct.Anna Zaks
We are not properly handling the memory regions that escape into struct fields, which led to a bunch of false positives. Be conservative here and give up when a pointer escapes into a struct. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@150658 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-16Use the new method for specifying garbage collection metadata in the module.Bill Wendling
The garbage collection metadata needs to be merged "intelligently", when two or more modules are linked together, and not merely appended. (Appending creates a section which is too large.) The module flags metadata method is the way to do this. <rdar://problem/8198537> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@150648 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-16Implicitly define a lambda's conversion functions (to functionDouglas Gregor
pointers and block pointers). We use dummy definitions to keep the invariant that an implicit, used definition has a body; IR generation will substitute the actual contents, since they can't be represented as C++. For the block pointer case, compute the copy-initialization needed to capture the lambda object in the block, which IR generation will need later. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@150645 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-15Revert "Add a completed/incomplete type difference. This allows us to have"Eric Christopher
This reverts commit 9a68d4584afcd0853b930bd80235b58736e785b4. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@150637 91177308-0d34-0410-b5e6-96231b3b80d8
2012-02-15Add a completed/incomplete type difference. This allows us to haveEric Christopher
partial types for contexts and forward decls while allowing us to complete types later on for debug purposes. This piggy-backs on the metadata replacement and rauw changes for temporary nodes and takes advantage of the incremental support I added in earlier. This allows us to, if we decide, to limit adding methods and variables to structures in order to limit the amount of debug information output into a .o file. The caching is a bit complicated though so any thoughts on untangling that are welcome. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@150631 91177308-0d34-0410-b5e6-96231b3b80d8

Snooping in other namespaces when the identifier being corrected is already qualified (i.e. a valid CXXScopeSpec is passed to CorrectTypo) and ranking synthesized namespace qualifiers relative to the existing qualifier is now performed. Support for disambiguating the string representation of synthesized namespace qualifers has also been added (the change to test/Parser/cxx-using-directive.cpp is an example of an ambiguous relative qualifier). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@150622 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-15Remove the unuseful -fdiagnostics-show-nameDavid Blaikie
This option was added in r129614 and doesn't have any use case that I'm aware of. It's possible that external tools are using these names - and if that's the case we can certainly reassess the functionality, but for now it lets us shave out a few unneeded bits from clang. Move the "StaticDiagNameIndex" table into the only remaining consumer, diagtool. This removes the actual diagnostic name strings from clang entirely.

2012-02-15Make -Wformat fix-its preserve original conversion specifiers.Hans Wennborg
This commit makes PrintfSpecifier::fixType() and ScanfSpecifier::fixType() only fix a conversion specification enough that Clang wouldn't warn about it, as opposed to always changing it to use the "canonical" conversion specifier. (PR11975) This preserves the user's choice of conversion specifier in cases like: printf("%a", (long double)1); where we previously suggested "%Lf", we now suggest "%La" printf("%x", (long)1); where we previously suggested "%ld", we now suggest "%lx". git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@150578 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-15Split reinterpret_casts of member pointers out from CK_BitCast; thisJohn McCall
is general goodness because representations of member pointers are not always equivalent across member pointer types on all ABIs (even though this isn't really standard-endorsed). Take advantage of the new information to teach IR-generation how to do these reinterprets in constant initializers. Make sure this works when intermingled with hierarchy conversions (although this is not part of our motivating use case). Doing this in the constant-evaluator would probably have been better, but that would require a *lot* of extra structure in the representation of constant member pointers: you'd really have to track an arbitrary chain of hierarchy conversions and reinterpretations in order to get this right. Ultimately, this seems less complex. I also wasn't quite sure how to extend the constant evaluator to handle foldings that we don't actually want to treat as extended constant expressions. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@150551 91177308-0d34-0410-b5e6-96231b3b80d8
