Ted Kremenek 8784a7c006 Add some boilerplate to report memory leaks at the end of an analyzed function. 
Still need some boilerplate in BugReporter to report bugs at the end
of a function (not associated with a particular statement).

 2008-04-11 22:25:11 +00:00
Ted Kremenek bc888b47b9 Added "EvalEndPath" to GRTransferFuncs: the default implementation does not 
change the state (and thus the GREndPathNodeBuilder automatically contructs a
node).

llvm-svn: 49563
 2008-04-11 22:07:59 +00:00
Ted Kremenek 811c2b4edb Added "GREndPathNodeBuilder", a new node builder that will be used for 
evaluating transfer functions at the end-of-path.

Ted Kremenek 831f327568 Fix regression introduced by my last commit. 
llvm-svn: 49556
 2008-04-11 20:23:24 +00:00
Ted Kremenek a7c44113bc Changed behavior of how we handle "NULL" summaries: just call 
GRSimpleVals::EvalCal(), and don't change reference counts.

Remove "getDoNothingSummary()", as a NULL summary does the same thing.

Added temporary hack for the "Get" rule for objects that return a pointer type:
treat them as non-owned CF objects.

Added test case to detect the release of a non-owned object.

 2008-04-10 21:11:47 +00:00
Dan Gohman 99b7b3f03b Teach InstCombine's ComputeMaskedBits to handle pointer expressions 
in addition to integer expressions. Rewrite GetOrEnforceKnownAlignment
as a ComputeMaskedBits problem, moving all of its special alignment
knowledge to ComputeMaskedBits as low-zero-bits knowledge.

Also, teach ComputeMaskedBits a few basic things about Mul and PHI
instructions.

This improves ComputeMaskedBits-based simplifications in a few cases,
but more noticeably it significantly improves instcombine's alignment
detection for loads, stores, and memory intrinsics.
