We also diagnose when initializers are used on declarations that aren't constructors:
t.cpp:1:10: error: only constructors take base initializers
void f() : a(10) { }

Doug and/or Sebastian: I'd appreciate a review, especially the nested-name-spec test results (from the looks of it we now match gcc in that test.)

failure to perform a declaration. Instead, explicitly note semantic
failures that occur during template parsing with a DeclResult. Fixes
PR3872.

of "object type" rather than the C definition of "object type". The
difference is that C's "object type" excludes incomplete types such as
struct X;
However, C's definition also makes it far too easy to use isObjectType
as a means to detect incomplete types when in fact we should use other
means (e.g., Sema::RequireCompleteType) that cope with C++ semantics,
including template instantiation.
I've already audited every use of isObjectType and isIncompleteType to
ensure that they are doing the right thing for both C and C++, so this
is patch does not change any functionality.

- -emit-llvm no longer changes what compilation steps are done.
- -emit-llvm and -emit-llvm -S write output files with .o and .s
suffixes, respectively.
- <rdar://problem/6714125> clang-driver should support -O4 and -flto,
like llvm-gcc
llvm-svn: 67645
- Don't default to using clang for C++ (use -ccc-clang-cxx to
override).
- Default to only using clang on i386 and x86_64 (use
-ccc-clang-archs "" to override).
- <rdar://problem/6712350> [driver] clang should not be used on
powerpc by default
- <rdar://problem/6705767> driver should default to -ccc-no-clang-cxx
I plan to add a warning that we are not using the clang compiler for
the given compilation so that users do not think clang is being used
in situations it isn't.
This change is motivated by the desire to be able to drop clang into a
build and have things "just work", even if it happens to get used to
compile C++ code or code for an architecture we don't support yet.

class C {
void g(C c);
virtual void f() = 0;
};
In this case, C is not known to be abstract when doing semantic analysis on g. This is done by recursively traversing the abstract class and checking the types of member functions.

these should disappear.

Based off of the patch in PR3342. (This doesn't implement -Wno-pointer-sign,
but I don't know the driver code very well.)

- Make the Diagnostic::Level for PTH errors to be specified by the caller
clang (driver):
- Set the PTHManager diagnostic level to "Diagnostic::Error" for -include-pth
(a hard error) and Diagnostic::Warning for -token-cache (we can still
proceed).

This speeds up getAsIdentifierInfo from being a call to a function
with a big switch to a single testl instruction. This speeds up
the example in PR3810 by 6.2%

its vectors based on the subobject type we're initializing and the
(unstructured) initializer list. This eliminates some malloc thrashing
when parsing initializers (from 117 vector reallocations down to 0
when parsing Cocoa.h). We can't always pre-allocate the right amount
of storage, since designated initializers can cause us to initialize
in non-predictable patterns.

- <rdar://problem/6669441> ccc doesn't handle assembler-with-cpp
semantics correctly (but clang supports it)
- This is sad, because it requires a fairly useless target
hook. C'est la vie.

- Add utility method SVal::GetConjuredSymbolVal() and constify some arguments
