These haven't been usable since the early return was accidentally removed some
years ago causing all cases to fall through to the !Enabled condition.

initialized from a constant expression in C++98, it can be used in
constant expressions, even if it was brace-initialized. Patch by

When clang is built outside of the LLVM tree (against a corresponding version),
there is no definition providing for operator<<(std::ostream &, StringRef) which
is required for the assertion routines in google-test tests. Avoid the
compilation failure by explicitly stringifying the StringRef prior to use.

A return type is the declared or deduced part of the function type specified in
the declaration.
A result type is the (potentially adjusted) type of the value of an expression
that calls the function.
Rule of thumb:
* Declarations have return types and parameters.
* Expressions have result types and arguments.

Reduces the ARCMT migrator plist writer down to a single function,
arcmt::writeARCDiagsToPlist() which shares supporting functions with the
analyzer plist writer.

Previously, string literals were ignored in all logical expressions. This
reduces it to only ignore in logical and expressions.

allow this, and we should warn on it, but it turns out that people were already
relying on this.
We should introduce a -Wgcc-compat warning for this if the attributes are known
to GCC, but we don't currently track enough information about attributes to do
so reliably.

might have a smaller size as compared to the stand-alone type of the base class.
This is possible when the derived class is packed and hence might have smaller
alignment requirement than the base class.

MSAN detected a path that leaves DeprecatedStringLiteralToCharPtr uninitialized.
UserDefinedConversionSequence::First is a StandardConversionSequence that must

This was done when we were not able to parse lambdas to handle some
edge cases for block formatting different in return statements, but is
not necessary any more.

member-declaration. In the process, fix a couple of bugs that had crept in
where we would parse the first and subsequent member-declarators differently
(in particular, we didn't accept an asm-label on a member function definition
within a class, and we would accept virt-specifiers and attributes in the wrong
order on the first declarator but not on subsequent ones).

This returns a list of valid (and useful) completions for a context (a list
of outer matchers), ordered by decreasing relevance then alphabetically. It
will be used by the matcher parser to implement completion.

Due to statement expressions supported as GCC extension, it is possible
to put 'break' or 'continue' into a loop/switch statement but outside
its body, for example:
for ( ; ({ if (first) { first = 0; continue; } 0; }); )
This code is rejected by GCC if compiled in C mode but is accepted in C++
code. GCC bug 44715 tracks this discrepancy. Clang used code generation
that differs from GCC in both modes: only statement of the third
expression of 'for' behaves as if it was inside loop body.
This change makes code generation more close to GCC, considering 'break'
or 'continue' statement in condition and increment expressions of a
loop as it was inside the loop body. It also adds error for the cases
when 'break'/'continue' appear outside loop due to this syntax. If
code generation differ from GCC, warning is issued.

This is a simpler rule, broadly in line with previous Darwin (which chose
between "soft" and "softfp") but probably safer. In practice the only real
reason for "softfp" is ABI compatibility, not usually an issue on limited chips
like these, so anyone who wanted hard-float should already be saying so.
That's my story and I'm sticking to it.

More universal way of removing trailing whitespace characters then 'chomp' does. Chomp "removes any trailing string that corresponds to the current value of $/" (quote from perldoc). In my case an input ended with '\r\r\n', chomp left '\r' at the end of input and the script ended up with an error "Use of uninitialized value in concatenation (.) or string"
