Ted Kremenek 7716cd62b3 Modify CursorVisitor to also walks CXXOperatorCallExprs using data-recursion. Fixes <rdar://problem/8659019>. 
llvm-svn: 118853
 2010-11-11 23:11:43 +00:00
Ted Kremenek 843c53828f RegionStore/BasicStore: do not return UndefinedVal for accesses to concrete addresses; instead return UnknownVal. This 
leads it up to checkers (e.g., DereferenceChecker) to guard against illegal accesses (e.g., null dereferences).

Fixes PR 5272 and <rdar://problem/6839683>.

Dan Gohman a826a88755 Factor out Instruction::isSafeToSpeculativelyExecute's code for 
testing for dereferenceable pointers into a helper function,
isDereferenceablePointer.  Teach it how to reason about GEPs
with simple non-zero indices.

Also eliminate ArgumentPromtion's IsAlwaysValidPointer,
which didn't check for weak externals or out of range gep
indices.

Andrew Trick f11344d770 Check TRI->getReservedRegs because other allocators do it. Even though 
it makes no sense for allocation_order iterators to visit reserved regs.
The inline spiller depends on AliasAnalysis.
Manage the Query state to avoid uninitialized or stale results.
