Ted Kremenek ea8dbdeefd Move ExplodedNode reclaimation out of ExprEngine and into CoreEngine. Also have it based on adding predecessors/successors, not node allocation. No measurable performance change.

Douglas Gregor 36107ade6f In Objective-C++, allow the keyword 'class' to be used as a property 
name for dot syntax, e.g., NSObject.class or foo.class. For other
C++-keywords-as-method-names, use message send syntax. Fixes
<rdar://problem/10794452>.

Jakob Stoklund Olesen bc6ba479b6 Remove the YMM_HI_6_15 hack. 
Call clobbers are now represented with register mask operands.  The
regmask can easily represent the fact that xmm6 is call-preserved while
ymm6 isn't.  This is automatically computed by TableGen from the
CalleeSavedRegs containing xmm6.

Argyrios Kyrtzidis 6aa70e2c83 Add fixits for ARC casting errors for implicit conversions as well. rdar://10289283 
Also fix the fixit (oh the irony) when it uses CFBridgingRetain/CFBridgingRelease;
they are supposed to be calls with the casted expression as parameter, they should
not be inserted into the cast like the __bridge keywords.

DeLesley Hutchins 3fc6e4a7cd Allow thread safety attributes on function definitions. 
For compatibility with gcc, clang will now parse gcc attributes on
function definitions, but issue a warning if the attribute is not a
thread safety attribute.  Warning controlled by -Wgcc-compat.

Hans Wennborg 9bc9bcc247 Format string analysis: give 'q' its own enumerator. 
This is in preparation for being able to warn about 'q' and other
non-standard format string features.

It also allows us to print its name correctly.

Alexey Samsonov ca37969c24 AddressSanitizer: don't include pthread.h and signal.h in interceptors on Mac 
llvm-svn: 150683
 2012-02-16 11:26:52 +00:00
Sebastian Redl 86fab844bb Make CXXNewExpr contain only a single initialier, and not hold the used constructor itself. 
Holding the constructor directly makes no sense when list-initialized arrays come into play. The constructor is now held in a CXXConstructExpr, if construction is what is done. The new design can also distinguish properly between list-initialization and direct-initialization, as well as implicit default-initialization constructors and explicit value-initialization constructors. Finally, doing it this way removes redundance from the AST because CXXNewExpr doesn't try to handle both the allocation and the initialization responsibilities.

This breaks the static analysis of new expressions. I've filed PR12014 to track this.
