Ted Kremenek 3a3f6e3946 Moved GRExprEngine::NodeSet out of GRExprEngine and made it a standalone class: ExplodedNodeSet. 
Made GRExprEngine::NodeSet a typedef of ExplodedNodeSet.

Ted Kremenek 229f6773bb For the transfer function of DeclStmt, for now initialize the values of 
structs (local variables) to Unknown instead of Undefined.  (added FIXME to initialize *members* of struct to undefined)

Ted Kremenek c490bdbdb1 TargetInfo objects now own the TargetInfoImpl objects they refer to. 
TargetInfo::AddSecondaryTarget is now private, as it is only used during
object construction.

Roman Levenstein c62c2bb4d0 Some improvements related to the computation of heights, depths of SUnits. 
The basic idea is that all these algorithms are computing the longest paths from the root node or to the exit node. Therefore the existing implementation that uses and iterative and potentially
exponential algorithm was changed to a well-known graph algorithm based on dynamic programming. It has a linear run-time.

Ted Kremenek 2a30ea6269 Fixed insidious state propagation bug that would sometimes cause the state 
to bifurcate at the wrong places and not propagate at others.

Bill Wendling 2ae707888b Did I say 'e = getNumOperands()'? I meant --e, of course.

Bill Wendling 0e541ea730 Miscellaneous clean-ups based on Evan's feedback: 
- Cleaned up how the prologue-epilogue inserter loops over the instructions.
- Instead of restarting the processing of an instruction if we remove an
  implicit kill, just update the end iterator and make sure that the iterator
  isn't incremented.

 2008-03-03 22:20:46 +00:00
Bill Wendling 632ea65072 This is the initial check-in for adding register scavenging to PPC. (Currently, 
PPC-64 doesn't work.) This also lowers the spilling of the CR registers so that
it uses a register other than the default R0 register (the scavenger scrounges
for one). A significant part of this patch fixes how kill information is
handled.
