precisely match the pattern and logic used by the GCC driver on Linux as
of a recent SVN checkout.

This happens to follow a *much* more principled approach. There is
a strict hierarchy of paths examined, first with multilib-suffixing,
second without such suffixing. Any and all of these directories which
exist will be added to the library search path when using GCC.

There were many places where Clang followed different paths, omitted
critical entries, and worst of all (in terms of challenges to debugging)
got the entries in a subtly wrong order.

If this breaks Clang on a distro you use, please let me know, and I'll
work with you to figure out what is needed to work on that distro. I've
checked the behavior of the latest release of Ubuntu, OpenSUSE, Fedora,
and Gentoo. I'll be testing it on those as well as Debian stable and
unstable and ArchLinux. I may even dig out a Slackware install.

No real regression tests yet, those will follow once I add enough
support for sysroot to simulate various distro layouts in the testsuite.

Fix another major performance regression in LiveVariables by not canonicalizing the underlying ImmutableSets on every analyzed statement (just at merges).  Fixes <rdar://problem/10087538>.

increasingly prevailing case to the point that new features
like ARC don't even support the fragile ABI anymore.

This required a little bit of reshuffling with exceptions
because a check was assuming that ObjCNonFragileABI was
only being set in ObjC mode, and that's actually a bit
obnoxious to do.

Most, though, it involved a perl script to translate a ton
of test cases.

Mostly no functionality change for driver users, although
there are corner cases with disabling language-specific
exceptions that we should handle more correctly now.

part on patches by Peter Collingbourne.

We diverge from the C++11 standard in a few areas, mostly related to checking
constexpr function declarations, and not just definitions. See WG21 paper
N3308=11-0078 for details.

Function invocation substitution is not available in this patch; constexpr
functions cannot yet be used from within constant expressions.

return attribute, to be casted without a bridge cast.
Tie this mechanism in with the existing exceptions to
the cast restrictions.  State those restrictions more
correctly and generalize.

to take a FunctionDecl* instead of an llvm::StringRef.  Eventually
we might push more logic in there, like using slightly different
conventions for C++ methods.

Also, fix a bug where 'copy' and 'create' were being caught in 
non-camel-cased strings.  We want copyFoo and CopyFoo and XCopy
but not Xcopy or xcopy.

This patch may do what it describes, it may not. It's hard to tell as
its completely unclear what this is supposed to do. There are also no
test cases. More importantly, this seems to have broken lots of linker
invocations on multilib Linux systems.

The manual pages for 'ld' on Linux mention translating a '=' at the
beginning of the path into a *configure time* sysroot prefix (this is,
I believe, distinct from the --sysroot flag which 'ld' also can
support). I tested this with a normal binutils 'ld', a binutils 'ld'
with the sysroot flag enabled, and gold with the sysroot flag enabled,
and all of them try to open the path '=/lib/../lib32', No translation
occurs.

I think at the very least inserting an '=' needs to be conditioned on
some indication that it is supported and desired. I'm also curious to
see what toolchain and whan environment cause it to actually make
a difference.

I'm going to add a test case for basic sanity of Linux 'ld' invocations
from Clang in a follow-up commit that would have caught this.

Patch by Paolo Capriotti!

llvm-svn: 140864

Remove the conditional that avoided passing the Objective-C runtime specification flags to cc1.  This fixes PR10369 (__builtin_NSStringMakeConstantString() selecting the wrong runtime in C / C++ code and crashing, although it doesn't fix the problem that instantiating the Mac runtime for non-Darwin targets was crashing.) 

llvm-svn: 140853

Fix a bug in the token caching for inline constructors in C++11, and improve error recovery in both dialects. This should fix the GCC test suite failures as well.

llvm-svn: 140847

CoreFoundation object-transfer properties audited, and add a #pragma
to cause them to be automatically applied to functions in a particular
span of code.  This has to be implemented largely in the preprocessor
because of the requirement that the region be entirely contained in
a single file;  that's hard to impose from the parser without registering
for a ton of callbacks.

llvm-svn: 140846

Fix crash when analyzing C++ code involving constant enums and switch statements (<rdar://problem/10202899>).

[analyzer] Fix a bug in RetainReleaseChecker diagnostics. It gives more precise error message on the modified test case (and prevents duplicate diagnostics when we purge at block granularity).

llvm-svn: 140840

[analyzer] Add -analyzer-purge option which can take on multiple values, remove -analyzer-purge=none. (Small refactor as well: move the work of constructing AnalysisManager from the callers to the class itself.)

Some fixes for MS-style asm parsing: specifically, add some error checking, and handle asm comments using semicolons correctly.  (The comments are actually surprisingly tricky.)
