Dmitri Gribenko 941ab0fb6f Remove a const_cast by propagating constness to the member function.

Duncan Sands 4698cb339f Fix the IntegersSubsetTest unit test when compiled with gcc-4.7. The issue here 
is that the unit test doesn't have IntTy equal to APInt, instead it uses a class
derived from APInt.  When, as in these lines, an IntTy& reference is returned
but is assigned to an APInt&, the compiler destroys the temporary the IntTy& was
referring to, leaving the APInt& referring to garbage.  This causes the unittest
to fail systematically on my machine; it can also be caught by running the test
under valgrind.

NAKAMURA Takumi ba15a7974a StaticAnalyzer/Core/ExprEngineCallAndReturn.cpp: Appease msvc. 
0 (as nullptr) is incompatible to pointer in type matching on msvc.

Duncan Sands a318ef6fa6 Generalize the transform that boosts GEP indices to the size of a pointer to 
also do it for vectors of pointers.

Eli Friedman 34ff0ea522 Add a proper algorithm to compute accurate source ranges for diagnostics with 
caret locations and source ranges in macros.  Makes ranges more accurate
in some cases, and fixes an assertion failure.

Fixes <rdar://problem/12472249>.

Anna Zaks 8d1f6ed9a8 [analyzer] Run remove dead on end of path. 
This will simplify checkers that need to register for leaks. Currently,
they have to register for both: check dead and check end of path.

I've modified the SymbolReaper to consider everything on the stack dead
if the input StackLocationContext is 0.

(This is a bit disruptive, so I'd like to flash out all the issues
asap.)

Anna Zaks 2510608e81 [analyzer] Refactor: Remove Pred from NodeBuilderContext. 
Node builders should manage the nodes, not the context.

Jim Ingham a537f6ce37 Fix a little think-o. In FileSpec::operator== we were trying to figure out whether the rhs file was resolved or not by comparing 
the resolved version of the rhs FileSpec's directory name with the lhs FileSpec's directory name.  We really meant to compare it
with the rhs FileSpec's directory name...

Jordan Rose 829c383114 [analyzer] Add some convenience accessors to CallEvent, and use them. 
These are CallEvent-equivalents of helpers already accessible in
CheckerContext, as part of making it easier for new checkers to be written
using CallEvent rather than raw CallExprs.

Jordan Rose 0da6747901 [analyzer] isCLibraryFunction: check that the function is at TU-scope. 
Also, Decls already carry a pointer to the ASTContext, so there's no need
to pass an extra argument to the predicate.

Akira Hatanaka 654e3b40f5 [mips] Do not reserve all 64-bit registers, but only the ones which need to be 
reserved. Without this fix, RegScavenger::getRegsAvailable incorrectly
returns an empty set of integer registers.
