With this option, arbitrarily named module map files can be specified
to be loaded as required for headers in the respective (sub)directories.
This, together with the extern module declaration allows for specifying
module maps in a modular fashion without the need for files called
"module.map".
Among other things, this allows a directory to contain two modules that
are completely independent of one another.

Review: http://llvm-reviews.chandlerc.com/D1546.
I have picked up this patch form Lawrence
(http://llvm-reviews.chandlerc.com/D1063) and did a few changes.
From the original change description (updated as appropriate):
This patch adds a check that ensures that modules only use modules they
have so declared. To this end, it adds a statement on intended module
use to the module.map grammar:
use module-id
A module can then only use headers from other modules if it 'uses' them.
This enforcement is off by default, but may be turned on with the new
option -fmodules-decluse.
When enforcing the module semantics, we also need to consider a source
file part of a module. This is achieved with a compiler option
-fmodule-name=<module-id>.
The compiler at present only applies restrictions to the module directly
being built.

literal operators. Also, for now, allow the proposed C++1y "il", "i", and "if"
suffixes too. (Will revert the latter if LWG decides not to go ahead with that
change after all.)

1. Fixed constructor of shared clause.
2. Some macros for clauses processing are replaced by private template methods.
3. Additional checks in sema analysis of OpenMP clauses.

Patch by Ana Pazos.
1.Added support for v1ix and v1fx types.
2.Added Scalar Pairwise Reduce instructions.
3.Added initial implementation of Scalar Arithmetic instructions.

gcc doesn't support "gcc -m sse" and this was not tested in clang and only
used for link argument on darwin, so this was very likely just a bug.

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.

This doesn't change a lot since clang still thinks it knows all of the
-f*, -m* and -W* options for example.
Other than the options clang explicitly claims to know, this fixes pr9701.

Summary:
We enable ASAN's use-after-return instrumentation at compile-time,
but still keep it disabled at run-time.
This enables the users to flip the flag at run-time using environment variable
ASAN_OPTIONS=detect_stack_use_after_return=1 instead of using a separate build.
If UAR detection is disabled at run-time, this extra compile-time instrumentation
costs very small slowdown. On SPEC 2006 14 tests are not affected at all,
4 tests get ~ 1% slowdown and 453.povray gets 4%.

Summary:
Parsing cast expressions during error recovery can put us in a bad
state. Check to see if the token for a simple-type-specifier makes
sense before further parsing.
Fixes PR17255.

an additional conversion (other than a qualification conversion) would be
required after the explicit conversion.
Conversely, do allow explicit conversion functions to be used when initializing
a temporary for a reference binding in direct-list-initialization.

A patch to AllocateTarget function to recognize llvm::Triple::NaCl for
MIPSEL and return NaClTargetInfo. Additional test has been added to check
if the expected macros get defined.

This solves the problem of fallback onto ourselves if clang-cl
has been renamed to cl.exe and put on the PATH, as happens with
the VS integration.

Apart from being more compact and already implemented, this also handles the
case where the parent is null. (It does also ignore all casts, not just
implicit ones, but this is more efficient to test and in the case we care
about---a message in a PseudoObjectExpr---there should only be implicit casts
anyway.
This should fix our internal buildbot.

Instead add the ASan runtime to the linker command line so that only the ASan API functions can be undefined in the target library.
