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.

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.

override for the type of 'this', also clear it out (unless we're entering the

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"

Some ABIs have different return types for constructors and

If there are non-trivially-copyable types /other/ than C++ records, we
won't have a synthesized copy expression, but we can't just use a simple
load/return.
Also, add comments and shore up tests, making sure to test in both ARC
and non-ARC.

This test requires asserts for now, and exception handling has an
awkward structure that leads to extra run lines. Because of this, the
test file's not a great place for other C++ PGO tests, but
instr-profile.cpp is obviously the better name for them.

Removes some old code that allowed a module to be loaded from a pcm file
even if the module.map could not be found. Also update a number of

create an implicit declaration of it (because some type it depends on is
unavailable). This had the effect of causing us to not implicitly give it the
right attributes. It turns out that glibc's __sigsetjmp is declared before
sigjmp_buf is declared, and this resulted in us not implicitly giving it
__attribute__((returns_twice)), which in turn resulted in miscompiles in any C
code calling glibc's sigsetjmp.

PNaCl and Emscripten can both handle va_arg IR instructions with
struct type.
Also add a test to cover generating a va_arg IR instruction from
va_arg in C on le32 (as already handled by VisitVAArgExpr() in
CGExprScalar.cpp), which was not covered by a test before.
