Douglas Gregor fc9e7a2969 If the precompiled header named by "-include" is actually a directory,
check each of the files within that directory to determine if any of
them is an AST file that matches the language and target options. If
so, the first matching AST file is loaded. This fixes a longstanding
discrepency with GCC's precompiled header implementation.

Richard Smith 2ddcbab8ff Ugly ugly hack for libstdc++-4.6 and libstdc++-4.7 compatibility. These
libraries have an incorrect definition of std::common_type (inherited from a
bug in the standard -- see LWG issue 2141), whereby they produce reference
types when they should not.

If we instantiate a typedef named std::common_type<...>::type, which is defined
in a system header as decltype(... ? ... : ...), and the decltype produces a
reference type, convert it to the non-reference type. (This doesn't affect any
LWG2141-conforming implementation of common_type, such as libc++'s, because the
default implementation of common_type<...>::type isn't supposed to produce a
reference type.)

This is horrible. I'm really sorry. :( Better ideas appreciated!

Michael J. Spencer 929fccd476 [Options] Add prefixes to options.
Each option has a set of prefixes. When matching an argument such as
-funroll-loops. First the leading - is removed as it is a prefix. Then
a lower_bound search for "funroll-loops" is done against the option table by
option name. From there each option prefix + option name combination is tested
against the argument.

This allows us to support Microsoft style options where both / and - are valid
prefixes. It also simplifies the cases we already have where options come in
both - and -- forms. Almost every option for gnu-ld happens to have this form.

Richard Smith db2630fb04 Unrevert r166268, reverted in r166272, with a fix for the issue which Nick
found: if an overloaded operator& is present before a template definition,
the expression &T::foo is represented as a CXXOperatorCallExpr, not as a
UnaryOperator, so we didn't notice that it's permitted to reference a non-static
data member of an unrelated class.

While investigating this, I discovered another problem in this area: we are
treating template default arguments as unevaluated contexts during substitution,
resulting in performing incorrect checks for uses of non-static data members in
C++11. That is not fixed by this patch (I'll look into this soon; it's related
to the failure to correctly instantiate constexpr function templates), but was
resulting in this bug not firing in C++11 mode (except with -Wc++98-compat).

Original message:

PR14124: When performing template instantiation of a qualified-id outside of a
class, diagnose if the qualified-id instantiates to a non-static class member.

Richard Smith 66f3ac9d21 Rework implementation of DR1492: Apply the resolution to operator delete too,
since it also has an implicit exception specification. Downgrade the error to
an extwarn, since at least for operator delete, system headers like to declare
it as 'noexcept' whereas the implicit definition does not have an explicit
exception specification. Move the exception specification for user-declared
'operator delete' functions from the type-as-written into the type, to reflect
reality and to allow us to detect whether there was an implicit exception spec
or not.

Nico Weber 206e0ecaa2 Accept -Wno-arc-abi without warning for a while.
Xcode 4.5 passes -Wno-arc-abi to clang, which makes a clang newer than
r163917 warn that it doesn't understand -Wno-arc-abi. I asked if adding
this is ok at
http://lists.cs.uiuc.edu/pipermail/cfe-commits/Week-of-Mon-20121015/066433.html
and nobody objected.

this is a burden on for clang, shout, and I'll revert this.

Jordan Rose 3957fd5858 [analyzer] Assume 'new' never returns NULL if it could throw an exception.
This is actually required by the C++ standard in
[basic.stc.dynamic.allocation]p3:

  If an allocation function declared with a non-throwing
  exception-specification fails to allocate storage, it shall return a
  null pointer. Any other allocation function that fails to allocate
  storage shall indicate failure only by throwing an exception of a type
  that would match a handler of type std::bad_alloc.

We don't bother checking for the specific exception type, but just go off
the operator new prototype. This should help with a certain class of lazy
initalization false positives.

Also, unify ObjCShouldCallSuperDealloc and ObjCShouldCallSuperFinalize.
The two have identical behavior and will never be active at the same time.

There's one last simplification now, which is that if we see a call to
[super foo] and we are currently in a method named 'foo', we will
/unconditionally/ clear the ObjCShouldCallSuper flag, rather than check
first to see if we're in a method where calling super is required. There's
no reason to pay the extra lookup price here.

Andy Gibbs 0fea04509a Change VerifyDiagnosticConsumer so that it *must* contain at least one "expected-*" directive. As a result, for test-cases that are not expected to generate any diagnostics, an additional directive "expected-no-diagnostics" has been implemented which can then be included in such test-cases. This new directive may not be used in conjunction with any other "expected-*" directive.
This change was initially proposed as a solution to the problem highlighted by check-in r164677, i.e. that -verify will not cause a test-case failure where the compile command does not actually reference the file.

Eli Friedman eaf3414979 Fix Objective-C implicit property synthesis for C++ classes so we use valid
source locations in places where it is necessary for diagnostics.  By itself,
this causes assertions, so while I'm here, also fix property synthesis
for properties of C++ class type so we use so we properly set up a scope
and mark variable declarations.

Chad Rosier 791bbe298d [ms-inline asm] Have the LookupInlineAsmIdentifier() callback function return a
*NamedDecl.  In turn, build the expressions after we're finished parsing the
asm.  This avoids a crasher if the lookup fails.
