Eli Friedman ad811f01d5 Make clang behave in a gcc-compatible way in the presence of multiple flags for the same x86 target feature (e.g. -mno-sse -msse). gcc uses a somewhat unintuitive algorithm here in that the enabled SSE instructions is based on the order of the *last* flag for *each* feature-level, so that "-mno-sse -msse2" only enables SSE2, but "-mno-sse -msse2 -msse" enables all SSE levels.
Issue reported on cfe-dev.

Chandler Carruth edc2c64630 Move the Sema argument to all of the Sema-using helper functions in
SemaDeclAttr to the first argument. This makes them follow the very
consistent policy elsewhere in Sema for helper functions.

Original patch by Caitlin Sadowski, with some tweaking by me.

Chandler Carruth ff4c4f0f8a Mechanical rename of 'd' Decl pointer parameters to 'D'. This is more
conventional in the rest of Clang's codebase, and closer to the current
style recommendations. It also makes the code more internally consistent
as FD, VD, etc are used frequently for particular decl variables.

 is a ParenListExpr and when it is a ParenExpr.
-Ultimately make Sema::ActOnParenOrParenListExpr independent of what the cast type was.

Richard Trieu 94942b32a3 For code such as:
int f(int x) {
  if (int foo = f(bar)) {}
  return 0;
}

Clang produces the following error messages:

paren_imbalance.cc:2:19: error: use of undeclared identifier 'bar'
  if (int foo = f(bar)) {}
                  ^
paren_imbalance.cc:2:26: error: expected ')'
  if (int foo = f(bar)) {}
                        ^
paren_imbalance.cc:2:6: note: to match this '('
  if (int foo = f(bar)) {}
     ^

The second error is incorrect.  This patch will stop Clang from producing an error on parenthesis imbalance during error recovery when there isn't one.

Richard Smith cd1c055528 Fix AST representations of alias-declarations which define tag types. Inside classes, the tag types need to have an associated access specifier, and inside function definitions, they need to be included in the declarations of the DeclStmt. These issues manifested as assertions during template instantiation, and also in a WIP constexpr patch.

Douglas Gregor 3cc1581020 When we create a precompiled preamble, don't copy the
CompilerInvocation on the stack, because other objects (e.g., the
CompilerInstance) maintain an intrusive reference-counted pointer to
the CompilerInvocation. This doesn't matter in the normal case,
because we take back the CompilerInvocation. However, during crash
recovery, this leads to us trying to free an object on the stack, and
hilarity ensues. Fixes <rdar://problem/9652540>.

John McCall 2de1c33f77 Just mangle substituted template parameter types as unresolved types.
This is kindof questionable but seems to do more-or-less the right thing.
This is not a particularly friendly part of the ABI.

Douglas Gregor 678d76c026 Introduce the notion of instantiation dependence into Clang's AST. A
type/expression/template argument/etc. is instantiation-dependent if
it somehow involves a template parameter, even if it doesn't meet the
requirements for the more common kinds of dependence (dependent type,
type-dependent expression, value-dependent expression).

When we see an instantiation-dependent type, we know we always need to
perform substitution into that instantiation-dependent type. This
keeps us from short-circuiting evaluation in places where we
shouldn't, and lets us properly implement C++0x [temp.type]p2.

In theory, this would also allow us to properly mangle
instantiation-dependent-but-not-dependent decltype types per the
Itanium C++ ABI, but we aren't quite there because we still mangle
based on the canonical type in cases like, e.g.,

  template<unsigned> struct A { };
  template<typename T>
    void f(A<sizeof(sizeof(decltype(T() + T())))>) { }
  template void f<int>(A<sizeof(sizeof(int))>);

and therefore get the wrong answer.

Patch by Caitlin Sadowski.

Unfortunately, this attribute doesn't seem to have a single test. It is
only mentioned in comments in one test, and as a string literal in
a copy of some Clang code checked in as a test for the Indexer. =[ It
dates from 2009 r74280 as part of OpenCL 1.0.

Argyrios Kyrtzidis 8cc0459907 Introduce a caching mechanism for macro expanded tokens.
Previously macro expanded tokens were added to Preprocessor's bump allocator and never released,
even after the TokenLexer that were lexing them was finished, thus they were wasting memory.
A very "useful" boost library was causing clang to eat 1 GB just for the expanded macro tokens.

Introduce a special cache that works like a stack; a TokenLexer can add the macro expanded tokens
in the cache, and when it finishes, the tokens are removed from the end of the cache.

Now consumed memory by expanded tokens for that library is ~ 1.5 MB.
