Ted Kremenek d31b2637ab Patch by Cristian Draghici:
Enhance the printf format string checking when using the format
specifier flags ' ', '0', '+' with the 'p' or 's' conversions (since
they are nonsensical and undefined).  This is similar to GCC's
checking.

Also warning when a precision is used with the 'p' conversin
specifier, since it has no meaning.

Anders Carlsson 5d40c6f658 Check in the beginnings of my new vtable layout builder idea.
Right now, it's off by default but can be tested by passing -fdump-vtable-layouts to clang -cc1. This option will cause all vtables that will normally be emitted as part of codegen to also be dumped using the new layout code.

I've also added a very simple new vtable layout test case.

Ted Kremenek 510ee2594e Use the allocator associated with ASTContext to allocate the args
array associated with NonNullAttr.  This fixes yet another leak when
ASTContext uses a BumpPtrAllocator.

Ted Kremenek da4e0d350c Have ~ASTContext() delete StoredDeclsMap (internal to DeclContext) by
storing the set of StoredDeclsMaps in an internal vector of void*.
This isn't an ideal solution, but for the time being this fixes a
major memory leak with these DenseMaps not being freed.

Ted Kremenek 7f4945aa9c Remove use of 'std::string' from Attr objects, using instead a byte
array allocated using the allocator in ASTContext.  This addresses
these strings getting leaked when using a BumpPtrAllocator (in
ASTContext).

Charles Davis bbc0aa5166 Add support for the force_align_arg_pointer attribute. This is an x86-specific
attribute, so it uses Anton's new target-specific attribute support. It's
supposed to ensure that the stack is 16-byte aligned, but since necessary
support is lacking from LLVM, this is a no-op for now.

Daniel Dunbar 3241d400c8 Switch to using -fsjlj-exceptions instead of hard-coding it. Notably, this fixes

Douglas Gregor 811663eb11 Implement basic support for importing source locations from one AST
into another AST, including their include history. Here's an example
error that involves a conflict merging a variable with different types
in two translation units (diagnosed in the third AST context into
which everything is merged).

/Volumes/Data/dgregor/Projects/llvm/tools/clang/test/ASTMerge/Inputs/var2.c:3:5:
error: external variable 'x2' declared with incompatible types in
different translation units ('int' vs. 'double')
int x2;
    ^
In file included from
/Volumes/Data/dgregor/Projects/llvm/tools/clang/test/ASTMerge/Inputs/var1.c:3:
/Volumes/Data/dgregor/Projects/llvm/tools/clang/test/ASTMerge/Inputs/var1.h:1:8:
note: declared here with type 'double'
double x2;
       ^

Although we maintain include history, we do not maintain macro
instantiation history across a merge. Instead, we map down to the
spelling location (for now!).

Fariborz Jahanian 4587803919 Implement synthesizing properties by default.
This is a non-fragile-abi feature only. Since it

until further notice. WIP.

John McCall ab26cfa58d Standardize the parsing of function type attributes in a way that
follows (as conservatively as possible) gcc's current behavior:  attributes
written on return types that don't apply there are applied to the function
instead, etc.  Only parse CC attributes as type attributes, not as decl attributes;
don't accepet noreturn as a decl attribute on ValueDecls, either (it still
needs to apply to other decls, like blocks).  Consistently consume CC/noreturn
information throughout codegen;  enforce this by removing their default values
in CodeGenTypes::getFunctionInfo().
