In the test case one type is coming from a typedef with no default arg, the
other has the default arg. Taking the default arg from the typedef crashes, so
always use the real template paramter declaration. PR17510.

This solves two problems:
1) MSBuild will not flag the build as unsuccessful just because we print
an error in the output, since "error(clang):" doesn't seem to match
the regex it's using.
2) It becomes more clear that the diagnostic is coming from clang as
supposed to cl.exe.

"long long" which is currently technically only "reserved for future" use in OpenCL, but
since clang in OpenCL mode supports it we may as well test the modifications to
the settings made for that type.

Various tests had sprung up over the years which had --check-prefix=ABC on the
RUN line, but "CHECK-ABC:" later on. This happened to work before, but was
strictly incorrect. FileCheck is getting stricter soon though.

It turns out that Plum Hall depends on us not emitting an error on
integer literals which fit into long long, but fit into
unsigned long long. So C99 conformance requires not conforming to C99. :)

Switch some warnings over to errors which should never have been warnings
in the first place. (Also, a minor fix to the preprocessor rules for
integer literals while I'm here.)

attach, rather than merging all comments on the declaration chain. This gives a
more faithful dump, and has the side benefit of unbreaking uses of dump() from
within AST deserialization (where the redeclaration chain may not be sane).
llvm-svn: 182350
ASTDumper was already trying to do this & instead got an implicit bool
conversion by surprise (thus printing out 0 or 1 instead of the name of
the declaration). To avoid that issue & simplify call sites, simply make
it the normal/expected operator<<(raw_ostream&, ...) overload & simplify
all the existing call sites. (bonus: this function doesn't need to be a
member or friend, it's just using public API in DeclarationName)
llvm-svn: 181832
This is a fix for PR15895, where Clang will crash when trying to print a
template diff and the template uses an address of operator. This resulted
from expecting a DeclRefExpr when the Expr could have also been
UnaryOperator->DeclRefExpr.

VerifyDiagnosticConsumer previously would not check that the diagnostic and
its matching directive referenced the same source file. Common practice was
to create directives that referenced other files but only by line number,
and this led to problems such as when the file containing the directive
didn't have enough lines to match the location of the diagnostic in the
other file, leading to bizarre file formatting and other oddities.
This patch causes VerifyDiagnosticConsumer to match source files as well as
line numbers. Therefore, a new syntax is made available for directives, for
example:
// expected-error@file:line {{diagnostic message}}
This extends the @line feature where "file" is the file where the diagnostic
is generated. The @line syntax is still available and uses the current file
for the diagnostic. "file" can be specified either as a relative or absolute
path - although the latter has less usefulness, I think! The #include search
paths will be used to locate the file and if it is not found an error will be
generated.
The new check is not optional: if the directive is in a different file to the
diagnostic, the file must be specified. Therefore, a number of test-cases
have been updated with regard to this.
This closes out PR15613.

expressions are integer. It can also be ValueDecl expressions
Use the type information from the TemplateParameterList instead
Patch by Olivier Goffart!
llvm-svn: 178611
When support was added for declaration arguments, the case of variadic
declaration arguments was not supported. This patch fixes that problem by
not crashing when certain ValueDecl's are null.

Value depenedent expressions for default arguments cannot be evaluated.
Instead, use the desugared template type to get an argument expression that
can be used. This is needed for both integer and declaration arguements.
Also, move this common code into a separate function.
Patch by Olivier Goffart!
llvm-svn: 178609
When the template argument is both default and value dependent, the expression
retrieved for the default argument cannot be evaluated, thus never matching
any argument value. To get the proper value, get the template argument
from the desugared template specialization. Also, output the original
expression to provide more information about the argument mismatch.

them the same if they are actually the same; having the same name isn't enough.
Similar to r174013, template template arguments were also mistakenly considered
the same when they had the same name but were in different namespaces.
In addition, when printing template template arguments, use the qualified name
if the regular name is the same.

AST dumping now looks like this:
