"write" attribute (copy/retain/etc.). But, property declaration in
primary class and protcols are tentative as they may be overridden
into a 'readwrite' property in class extensions. Postpone diagnosing
such warnings until the class implementation is seen.

Stop depending on the LiveIntervalUnions in RegAllocBase, they are about
to be removed.
The changes are mostly replacing register alias iterators with regunit
iterators, and querying LiveRegMatrix instrad of RegAllocBase.
InterferenceCache is converted to work with per-regunit
LiveIntervalUnions, and it checks fixed regunit interference separately,
using the fixed live intervals provided by LiveIntervalAnalysis.
The local splitting helper calcGapWeights() is also considering fixed
regunit interference which is kept on the side now.

For the allocations that do not belong to any malloc zone check whether they're padded with a pointer to ASan's CFAllocator. If so, free the original (unpadded) pointer.
This should fix AddressSanitizerMac.NSURLDeallocation and issue 70.

places. I've turned this off for the GNU runtimes --- I don't know if
they support weak class import, but it's easy enough for them to opt in.
Also tweak a comment per review by Jordan.

* Escape < characters in Doxygen comments as needed;
* Add \code...\endcode around code examples;
* Remove an incorrect use of Doxygen's \arg command.

That is a DenseMap iterator keyed by pointers, so the iteration order is
nondeterministic.
I would like to replace the DenseMap with an IndexedMap which doesn't
allow iteration.

Now that this is a C-only warning, we can use "static" instead of "internal
linkage", which is a term developers are probably more familiar with.
This makes for a better warning message. The warning name was changed to match,
since "internal linkage" is not mentioned in the warning text anymore.
llvm-svn: 158853
* Many fixes for \brief summaries (adding some, and making others shorter);
* Don't try to explicit tell Doxygen a namespace name (and particularly
don't get it wrong);
* Typo fix: instantitions -> instantiations;
* Slightly more use of \pre for documenting preconditions.

Similar to r156661. This should be beneficial performance wise and
hopefully, resolve a RecursiveASTVisitor crash that we are seeing in the
wild, but are incapable of reproducing.

This commits sets the grounds for more aggressive use after free
checking. We will use the Relinquished sate to denote that someone
else is now responsible for releasing the memory.

MipsGenRegisterInfo.inc. Suggested by Jakob Stoklund Olesen.
Also, fix bug in function DecodeAFGR64RegisterClass.

in microsoft mode. Fixes PR12701.
The code for this was already in 2 of the 3 branches of a
conditional and missing in the 3rd branch, so lift it above
the conditional.

This is supported by gcc and clang, but guarded by a macro for MSVC 2008.
The extern template declaration is not necessary but generally good
form. It can avoid extra instantiations of the template methods
defined inline.
The EXTERN_TEMPLATE_INSTANTIATION macro could probably be generalized to
handle multiple template parameters if someone thinks it's worthwhile.

It's very easy for anonymous external linkage to propagate in C++ through
return types and parameter types. Likewise, it's possible that a template
containing an inline function is only used with parameters that have internal
linkage. Actually diagnosing where the internal linkage comes from is fairly
difficult (both to locate and then to print nicely). Finally, since we only
have one translation unit available, we can't even prove that any of this
violates the ODR.
This warning needs better-defined behavior in C++ before it can really go in.
Rewording of the C warning (which /is/ specified by C99) coming shortly.

error was asserting on anything that included Windows.h. MS-style inline asm is
still dropped, but at least now we're not completely silent about it.

CreateEnumType doesn't participate in caching so the descriptor for the enum
gets recomputed for every reference of an element of an enum, only to get
discarded when it gets turned into an MDNode.
No functionality change except performance.

Regunit live ranges are computed on demand, so when mi-sched calls
handleMove, some regunits may not have live ranges yet.
That makes updating them easier: Just skip the non-existing ranges. They
will be computed correctly from the rescheduled machine code when they
are needed.
