PCHReader doesn't implement classof so dyn_casting it will do really weird stuff. Use a static_cast instead.

I don't know if this hack is the right fix. Doug, please take a look.

This fixes a really nasty bug in Darwin::getDarwinArchName where we were going
StringRef -> temporary std::string -> StringRef (and return the dead StringRef).
The StringRefs from Triple live as long as the Triple itself, that should be
long enough.

Hopefully 2 of 4 MSVC buildbot failures are gone now.

- URL can go into read only memory now.
- Compilers will fold away all the strstr calls.

Add basic type checking of format string conversion specifiers and their arguments.  Thanks to Cristian Draghici for his help with this patch!

the field width and precision of a format specifier instead of just
'int'.  This matches GCC, and fixes <rdar://problem/6079850>.

Per a suggestion from Cristian Draghici, add a method to FormatSpecifier that returns the expected type of the matching data argument.  It isn't complete, but should handle several of the important cases.

The right fix here is PR6175, although we would still have to find a different
work around for the gdb test suite.

checking.  It passes all existing tests, and the diagnostics have been
refined to provide better range information (we now highlight
individual format specifiers) and more precise wording in the
diagnostics.

- Add ConversionSpecifier::consumesDataArgument() as a helper method
  to determine if a conversion specifier requires a matching argument.
- Add support for glibc-specific '%m' conversion
- Add an extra callback to HandleNull() for locations within the
  format specifier that have a null character

previously, we were allowing this to bind to a temporary. Now, we
don't; add test-cases and improve diagnostics.

requires a temporary. Previously, we were building an initialization
sequence that bound to the bit-field as if it were a real lvalue. Note
that we previously (and still) diagnose binding of non-const
references to bit-fields, as we should.

There's no real way to test that this code is correct, since reference
binding does not *currently* have any representation in the AST. This
fix should make it easier for that to happen, so I've verified this
fix with...

Added InitializationSequence::dump(), to print an initialization
sequence for debugging purposes.

Add a new EmitLValueForFieldInitialization that will be used for initializing fields (and reference type fields in particular).

Simplify EmitLValueForField - we can get whether the field is part of a union or not from the FieldDecl (through its DeclContext).

code which mismatches the spec with regard to empty structures.

In addition, move ParseFormatString() and FormatStringHandler() from
the clang::analyze_printf to the clang namespace.  Hopefully this will
resolve some link errors on Linux.

Yet another attempt to make the Linux buildbots happy.  Apparently there are differences on how nested namespaces are handled...

Alternate format string checking: check if the number of format specifiers exceeds the number of arguments.

llvm-svn: 94785

Move definition of FormatStringHandler::~FormatStringHandler() within namespace directives.  Hopefully this will make the Linux buildbots happy.
