This fixes llvm.org/PR14860.
Before, we messed up the format of:
if (DeclaratorInfo.isFunctionDeclarator() &&
//getDeclSpecContextFromDeclaratorContext(Context) == DSC_top_level &&
Tok.is(tok::semi) && NextToken().is(tok::l_brace)) {
}

This addresses llvm.org/PR14864.
We used to completely mess this up and now format as:
Diag(NewFD->getLocation(),
getLangOpts().MicrosoftExt ? diag::ext_function_specialization_in_class :
diag::err_function_specialization_in_class)
<< NewFD->getDeclName();
llvm-svn: 171957
Clang doesn't understand it.
If someone wants to teach clang about that flag instead, please also add
support for -fno-diagnostics-parseable-fixits for consistency.
Until then, let the documentation match the current behavior.

(because they are part of some module) but have not been made visible
(because they are in a submodule that wasn't imported), filter out
those declarations unless both the old declaration and the new
declaration have external linkage. When one or both has internal
linkage, there should be no conflict unless both are imported.

-Wint-to-pointer-cast, added to match GCC's warning by the same name, doesn't
need to be in any other groups (as it isn't in any groups in GCC either).
Found in post-commit review by Ted Kremenek.

With the new setting, we are not going to inline any functions that are
more than 50 basic blocks. (The analyzer is 20% faster on several
especially bad benchmarks with the new default.)

In the source
static void f();
static void f();
template<typename T>
static void g() {
f();
}
static void f() {
}
void h() {
g<int>();
}
the call to f refers to the second decl, but it is only marked used at the end
of the translation unit during instantiation, after the third f decl has been
linked in.
With this patch we mark all subsequent decls used, so that it is easy to check
if a symbol is used or not.
llvm-svn: 171888
before doing the comparison.
This is because we can't set "FirstInDeclGroup" consistently; for example, when visiting a DeclStmt we will set
it but we don't set it on the result of clang_getCursorDefinition for a reference of the same declaration.
llvm-svn: 171878
In Clang/LLVM this seems to be the more common formatting for ##s. There
might still be case that we miss, but we'll fix those as we go along.
Before:
#define A(X)
void function ## X();
After:
#define A(X)
void function##X();
llvm-svn: 171862
This is a first step towards supporting more complex structures such
as #ifs inside unwrapped lines. This patch mostly converts the array-based
UnwrappedLine into a linked-list-based UnwrappedLine. Future changes will
allow multiple children for each Token turning the UnwrappedLine into a
tree.
No functional changes intended.

bits from the number of parameters. This brings the bitfields down from 33 bits
to 32 bits, reducing the size of Types by 4 bytes on 32-bit systems.
llvm-svn: 171827
The issue here is that if we have 2 leaks reported at the same line for
which we cannot print the corresponding region info, they will get
treated as the same by issue_hash+description. We need to AUGMENT the
issue_hash with the allocation info to differentiate the two issues.
Add the "hash" (offset from the beginning of a function) representing
allocation site to solve the issue.
We might want to generalize solution in the future when we decide to
track more than just the 2 locations from the diagnostics.
llvm-svn: 171825
The test should be looking for gcrt0.o not crt0.o. Clang was already printing
"gcrt0", but the test was looking for "{{.*}}crt0.o", and the .* regexp
consumed "g".

This is in preparation for using this to construct the function type for
pointers to member functions to include the implicit/artificial 'this'
parameter in that case as well. (feedback from GDB indicates that this might be
all that's necessary to get it to behave well with Clang's pointer-to-member
function debug output)
llvm-svn: 171809
This fixes the URL permanence of that URL. This is a bit of a hack. See
the FIXME in the patch for what the "real" solution should be.

DenseMap and the lookups associated with it.
Instead of lexing for preprocessor tokens, associating the annotation with the location in a map,
and later lookup in the map in order to adjust the cursor annotation, just annotate the cursor
while lexing for preprocessor tokens.
llvm-svn: 171775
Previously type/storage qualifiers would not be annotated as the declaration they belonged to.
Just use the resulting source range of getRawCursorExtent() which is more correct
than what AnnotateTokensWorker::Visit() was adjusting it to.
llvm-svn: 171774
this was ever a macro name and return a specific CXCursor_MacroExpansion cursor in such a case,
instead of the generic CXCursor_MacroDefinition.
Checking for macro name makes sure the identifier is not part of the identifier list in a
function macro.
While, in general, resolving identifiers in macro definitions to other macros may not be completely accurate,
it greatly improves functionality such as give-me-the-definition-of-this, which was not working at all
inside macro definitions.

Better handle the blacklisting of known bad deallocators when symbol
escapes through a call to CFStringCreateWithBytesNoCopy.

When a property is "inherited" through both a parent class and directly
through a protocol, we should not require the child to invalidate it
since the backing ivar belongs to the parent class.
(Fixes radar://12913734)

Previous indent:
class A {
}
a;
void f() {
};
With this patch:
class A {
} a;
void f() {
}
;
The patch introduces a production for classes and structs, and parses
the rest of the line to the semicolon after the class scope.
This allowed us to remove a long-standing wart in the parser that would
just much the semicolon after any block.
Due to this suboptimal formating some tests were broken.
Some unrelated formatting tests broke; those hit a bug in the ast
printing, and need to be fixed separately.
llvm-svn: 171761
Following r168626, in class declaration or definition, there are a combination of syntactic locations
where C++11 attributes could appear, and among those the only valid location permitted by standard is
between class-key and class-name. So for those attributes appear at wrong locations, fixit is used to
move them to expected location and we recover by applying them to the class specifier.

rehashed, invaliding the iterator walking through the identifier
table. Separate out the identification of out-of-date identifiers from
updating them.

with respect to the lower "left-hand-side bitwidth" bits, even when negative);
see OpenCL spec 6.3j. This patch both implements this behaviour in the code
generator and "constant folding" bits of Sema, and also prevents tests
to detect undefinedness in terms of the weaker C99 or C++ specifications
from being applied.
llvm-svn: 171755
This should make it slightly more readable as it more clearly separates
what happens where. No intended functional changes. More of this to
come..

Also set ObjC1 in the formatter tests.
The only effect of this flag in the lexer is that '@' now gets turned into
tok::at instead of tok::unknown.

This addresses llvm.org/PR14830.
Before:
unsigned Cost =
TTI.getMemoryOpCost(I->getOpcode(), VectorTy, SI->getAlignment(),
SI->getPointerAddressSpace());
CharSourceRange LineRange =
CharSourceRange::getTokenRange(TheLine.Tokens.front().Tok.getLocation(),
TheLine.Tokens.back().Tok.getLocation());
After:
unsigned Cost = TTI.getMemoryOpCost(I->getOpcode(), VectorTy,
SI->getAlignment(),
SI->getPointerAddressSpace());
CharSourceRange LineRange = CharSourceRange::getTokenRange(
TheLine.Tokens.front().Tok.getLocation(),
TheLine.Tokens.back().Tok.getLocation());
This required rudimentary changes to static initializer lists, but we
are not yet formatting them in a reasonable way. That will be done in a
subsequent patch.
