* Fix bug: test/Regression/Transforms/LevelRaise/2002-07-16-SourceAndDestCrash.ll
   - Add a new NewCasts member to VMC to keep track of casts that have been
     created and to ensure there is always a reference to the cast.
   - Extend ValueHandle a bit so it can be used in an STL container
   - Make sure we destroy the ValueMapCache before verifying the function
     in LevelRaise.cpp

llvm-svn: 2669
 2002-05-20 20:48:03 +00:00
Vikram S. Adve 47f37c3404 Hash pointer values to a sequence number to get identical results from 
lli and llc.  This is controlled with options -tracehash on|off.

Also, added an option to specify which functions should be traced.
Particularly useful to reduce output volume in basic-block tracing.

Chris Lattner 053c0939e3 Fix bug: test/Regression/Transforms/InstCombine/2002-05-14-TouchDeletedInst.ll 
"This testcase caused instcombine to fail because it got the same instruction on
it's worklist more than once (which is ok), but then deleted the instruction.
Since the inst stayed on the worklist, as soon as it came back up to be
processed, bad things happened, and opt asserted."

llvm-svn: 2623
 2002-05-14 15:24:07 +00:00
Chris Lattner a3c3456e7f Fix a major source of "type unsafety", where a cast is neccesary, but can 
be put either before or after a load.  We chose to cast the value loaded
instead of the pointer to load from.

  iterative.
* -constprop pass no longer "constant propogates" terminator instructions
   - CFG is now preserved!

  getNumIncomingValues.  This really belongs in InstCombine, anyway so we'll

Chris Lattner fe6c9eeae3 * Finish the implementation of isEdgeFeasible this fixes bug: 
test/Regression/Transforms/SCCP/2002-05-02-EdgeFailure.ll

  are in the program, not simplifying them.  A seperate pass should eliminate
  the potentially dead basic blocks and edges in the CFG.

  cannot produce a value anyway.
* Inline the OperandChangedState implementation

  exactly as before.
