- readonly and readwrite are mutually exclusive.
 - assign, copy, and retain are mutually exclusive.
 - copy and retain are invalid on non-object types.
 - Warn about using default 'assign' property on object types
   (attempting to follow gcc behavior).

Changed casing of many bug names.  The convention will be to have bug names (mostly) lower cased, and categories use some capitalization.

GRExprEngine:
  Use PostStore in EvalStore.
  Use a second version of EvalStore in EvalBinaryOperator to associate the store with the expression on the LHS.

Bug fix: for the base transfer function logic for casts, handle const casts as just propagating the value.

llvm-svn: 56368

For checking if a symbol >= value, we need to check if symbol == value || symbol
> value. When checking symbol > value and we know that symbol != value, the path
is infeasible only if value == maximum integer.

For checking if a symbol <= value, we need to check if symbol == value || symbol
< value. When checking symbol < value and we know that symbol != value, the path
is infeasible only if value == minimum integer.

Updated test case exercising this logic: we only prune paths if the values are
unsigned.

arbitrary expr, not just a assign expr.  The grammar comment
was right, the code was just wrong.

'symbol operator-reverse int'. This patch is a combination of code from
Zhongxing Xu and myself (Zhongxing noticed this bug for the cases of
relational operators).

Implement second part of PR 2600: NSError** parameter may be null, and should be checked before being dereferenced.

llvm-svn: 56318

Change implementation of NSError** coding-style check to be invoked at the end of the retain/release analysis.

Also added a couple simple tests from the "gcc.apple" test suite.

"Method accepting NSError** argument should have non-void return value to indicate that an error occurred."

Test case written, but the header needs to be delta-debugged reduced.  Will commit shortly.

 - Enables use of ABIArgInfo::Expand when needed. This greatly
   improves our x86 ABI compatibility.

 - As the infrastructure for target specific ABI handling isn't built
   yet, this change means ABI compatibility on other platforms is once
   again broken in a different way than before.

 - Upcoming: Figure out how to refactor ABI handling into
   targets. More documentation.

Ensure that ABIArgInfo::Default implementation for aggregrate types
is sensible (StructRet on return and ByVal on arguments).

No functionality change.

Block literals are now represented by the concrete BlockExpr class.

  if we know that 'len != 0' and know that 'i == 0' then we know that
  'i < len' must evaluate to true and cannot evaluate to false

 ^(expression) or ^(int arg1, float arg2)(expression)

All block literals now require a compound statement.

Sema::CheckReturnStackAddr(): Make sure we skip over implicit casts.
Added some more test cases...

motivated because it became clear that the number of subclasses of ProgramPoint
would expand and we ran out of bits to represent a pointer variant. As a plus of
this change, BlockEdge program points can now be represented explicitly without
using a cache of CFGBlock* pairs in CFG.

 - For investigating warnings in system headers / builtins.
 - Currently also enables the behavior that allows silent redefinition
   of types in system headers. Conceptually these are separate but I
   didn't feel it was worth two options (or changing LangOptions).
