headers even if they arrived when merging non-system modules.
The idea of this code is that we don't want to warn the user about
macros defined multiple times by their system headers with slightly
different definitions. We should have this behavior if either the
macro comes from a system module, or the definition within the module
comes from a system header. Previously, we would warn on ambiguous
macros being merged when they came from a users modules even though they
only showed up via system headers.
By surviving this we can handle common system header macro differences
like differing 'const' qualification of pointers due to some headers
predating 'const' being valid in C code, even when those systems headers
are pre-built into a system module.

This is complicated by the fact that we can't simply use side-effecting
calls in an argument list without losing all guarantees about the order
they're emitted. To keep things deterministic we use tuples and brace
initialization, which thankfully guarantees evaluation order.
No functionality change intended.

This is nearly identical to the v*f128_si256 parts of r231792 and r232052.
AVX2 introduced proper integer variants of the hacked integer insert/extract
C intrinsics that were created for this same functionality with AVX1.
This should complete the front end fixes for insert/extract128 intrinsics.
Corresponding LLVM patch to follow.

A nullptr exception object can be caught by any pointer type catch
handler. However, it is not possible to express this in the exception
info for the MS ABI. As a middle ground, allow such exception objects
to be caught with pointer-to-void catch handlers.

Update the doxygen configuration file and the Makefile build rules
to provide better output (simply use the default stylesheet and template
from the Doxygen distribution.)
This CL has upgrade doxygen.cfg.in to Doxygen 1.8.6.

In a static build the dependency is picked up implictly, but not in a shared
library build. This is needed for the new ObjC matchers that reference Selector.
llvm-svn: 232055
This is very much like D8088 (checked in at r231792).
Now that we've replaced the vinsertf128 intrinsics,
do the same for their extract twins.

Add some matchers for Objective-C selectors and messages to
ASTMatchers.h. Minor mods to ASTMatchersTest.h to allow test files with
".m" extension in addition to ".cpp". New tests added to
ASTMatchersTest.c.
Patch by Dean Sutherland.

Before:
A a = new A(){public String toString(){return "NotReallyA";
}
}
;
After:
A a = return new A() {
public String toString() {
return "NotReallyA";
}
};
This fixes llvm.org/PR22878.

This is a bit more involved than I anticipated, so here's a breakdown
of the changes:
1. Call ActOnFinishFunctionBody _after_ we parsed =default and
=delete specifiers. Saying that we finished the body before parsing
=default is just wrong. Changing this allows us to use isDefaulted
and isDeleted on a decl in ActOnFinishFunctionBody.
2. Check for -Wmissing-prototypes after we parsed the function body.
3. Disable -Wmissing-prototypes when the Decl isDeleted.

Sema overrides ASTContext's policy on the first emitted diagnostic
(doesn't matter if it's ignored or not). This means changing the order
of diagnostic emission in Sema suddenly changes the text of diagnostic
emitted from the parser.
In the test case -Wmissing-prototypes (ignored) was the culprit, use
'int main' to suppress that warning so we see when this regresses.
Also move it into Sema/ as it's not testing any C++.

For crashes with a VFS (ie, with modules), the -isysroot flag is often
necessary to reproduce the crash. This is especially true if some
modules need to be rebuilt, since without the sysroot they'll try to
read headers that are outside of the VFS.
I find it likely that we should keep some of the other -i flags in
this case as well, but I haven't seen that come up in practice yet so
it seems better to be conservative.
llvm-svn: 231997
When a crash report script doesn't work for a reproduction on your
machine for one reason or another, it can be really tricky to figure
out why not. The compiler version that crashed and the original
command line before stripping flags are very helpful when this comes
up.

Support for the QPX vector instruction set, used on the IBM BG/Q supercomputer,
has recently been added to the LLVM PowerPC backend. This vector instruction
set requires some ABI modifications because the ABI on the BG/Q expects
<4 x double> vectors to be provided with 32-byte stack alignment, and to be
handled as native vector types (similar to how Altivec vectors are handled on
mainline PPC systems). I've named this ABI variant elfv1-qpx, have made this
the default ABI when QPX is supported, and have updated the ABI handling code
to provide QPX vectors with the correct stack alignment and associated
register-assignment logic.
llvm-svn: 231960
This adds support for copy-constructor closures. These are generated
when the C++ runtime has to call a copy-constructor with a particular
calling convention or with default arguments substituted in to the call.
Because the runtime has no mechanism to call the function with a
different calling convention or know-how to evaluate the default
arguments at run-time, we create a thunk which will do all the
appropriate work and package it in a way the runtime can use.

definition, be sure to update the definition data on all declarations, not just
the canonical one, since the pattern might not be in the list of pending
