Summary: This makes the Mozilla style defaults more compliant with the Mozilla style guide. A few options were removed in order to use the LLVM style defaults.

Some of the the permissible ARM -mfpu options, which are supported in GCC,
are currently not present in llvm/clang.This patch adds the options:
'neon-fp16', 'vfpv3-fp16', 'vfpv3-d16-fp16', 'vfpv3xd' and 'vfpv3xd-fp16.
These are related to half-precision floating-point and single precision.

We had two separate paths for member pointer conversion: one which
takes a constant and another which takes an arbitrary value. In the
latter case, we are permitted to construct arbitrary instructions.
It turns out that the bulk of the member pointer conversion is sharable
if we construct an artificial IRBuilder.

A patch by Karthik Bhat!
This patch fixes a regression introduced by r224398. Prior to r224398
we were able to analyze the following code in test-include.c and report
a null deref in this case. But post r224398 this analysis is being skipped.
E.g.
// test-include.c
#include "test-include.h"
void test(int * data) {
data = 0;
*data = 1;
}
// test-include.h
void test(int * data);
This patch uses the function body (instead of its declaration) as the location
of the function when deciding if the Decl should be analyzed with path-sensitive
analysis. (Prior to r224398, the call graph was guaranteed to have a definition
when available.)

Nothing was hand edited afterward except a few literal strings

Get rid of code-path that (according to Richard Smith) is not needed but
leads to a crasher bug when assuming a template has been fully
instantiated and thus has a definition.

Attribute 'nodebug' means no llvm.dbg.* intrinsics, no !dbg
annotations, and no DISubprogram for the function.

Skip calls to HasTrivialDestructorBody() in the case where the
destructor is never invoked. Alternatively, Richard proposed to change
Sema to declare a trivial destructor for anonymous union member, which
seems too wasteful.

Before MSVS2015, MSVS's headers disagree about int32_t and PRIx32 and so on.
Provide a wrapper header to fix this, so that -Wformat can still be used.
Fixes PR23412.
llvm-svn: 240741
This patch fixes a crash caused by the following case:
template<typename T>
auto f(T x) {
auto g = [](auto ... args) {
auto h = [args...]() -> int {
return 0;
};
return h;
};
return g;
}
auto x = f(0)();
When the templated function 'f' is instantiated and the inner-most
lambda is transformed the ellipsis location on the captured variable
is lost. Then the lambda returned by 'f' is instantiated and the
tree transformer chokes on the invalid ellipsis location. The
problem is fixed by making a minor change to properly track the
ellipsis location.
This fixes PR23716.

In certain cases, the tree transform would introduce new TypoExprs while
trying one of the corrections, invalidating the unique_ptr in the state
reference, and also causing a TypoExpr to exist that will never be
corrected since it doesn't exist in the final corrected expression. The
simple solution to both problems is to temporarily disable typo
correction while handling potentially ambiguous typo corrections.

- Added the description of the interceptor suppression.
- Re-organized a bit: grouped a few things under the Issue Suppression
section, grouped IOC and leaks under a section, placed symbolication
info into Symbolizing the Reports section..
- In supported platforms: "MacOS" -> "OS X"; added "iOS Simulator"
- Added a paragraph to the Usage section describing when DYLD_INSERT_LIBRARIES
might need to be used.
- "attribute((no_sanitize_address))" -> "__attribute__((no_sanitize("address")))"
- Updated Leak Sanitizer page with most up to date info.

Ever since the target attributes change, we don't need to guard these
headers with `requires`. Actually it's a bit worse, because if we do
then they are included textually under the covers, causing declarations
to appear in submodules they aren't supposed to be in.
llvm-svn: 240720
Summary:
Namely, we must have proper C++ABI support in UBSan runtime. We don't
have a good way to check for that, so just assume that C++ABI support is
there whenever -fsanitize=vptr is supported (i.e. only on handful of
platforms).
Exact diagnostic is also tricky. It's not "cfi" that is unsupported,
just the diagnostic mode. So, I suggest to report that
"-fno-sanitize-trap=cfi-foobar" is incompatible with a given target
toolchain.

When a profile file cannot be opened, we used to display just the error
message but not the name of the profile the compiler was trying to open.
This will become useful in the next set of patches that introduce
GCC-compatible flags to specify profiles.

This patch implements the functionality specified by DR948.
The changes are two fold. First, the parser was modified
to allow 'constexpr's to appear in condition declarations
(which was a hard error before). Second, Sema was modified
to cleanup maybe odr-used declarations by way of a call to
'ActOnFinishFullExpr'. As 'constexpr's were not allowed in
condition declarations before the cleanup wasn't necessary
(such declarations were always odr-used).
This fixes PR22491.

This is exercised by existing tests, and fixes a failure with -fsanitize=null.
No observable change otherwise; the code happened to do the right thing in
practice under recent versions of Clang and GCC because
MacroDirective::getDefinition happens to check whether this == null.
llvm-svn: 240691
Summary:
For better or worse the OS X command line tools refer to the iOS simulator as iphonesimucator. We should provide an alias flag -miphonesimulator-version-min that matches a consistent pattern with the other tools.
This is in the interest of making it easier for people to write platform-agnostic darwin build scripts.
