Chris Lattner 4973805acd The levelraise pass is a broken old piece of crufty code that should be 
left on the side of the road without a second thought.

It is preventing forward progress, so for now, we will disable it by default.

Chris Lattner ad7b556813 Remove the -stopAfterNPasses option, which has been long obsoleted by bugpoint 
llvm-svn: 8278
 2003-08-31 21:47:24 +00:00
Chris Lattner 6f21fe9278 * move the dead-type-eliminate passes to the end, where they are more useful 
* add prune-eh and inlining passes
* other minor pass reorganizations

 2003-08-31 21:45:55 +00:00
Chris Lattner b8f72991a6 Completely remove mention of the correlated branch elimination pass. It has 
bugs and needs to be reworked anyway.

llvm-svn: 7692

Misha Brukman 250bf3674c * The possessive third-person singular has no apostrophe (its)

llvm-svn: 5898
 2003-04-24 18:26:03 +00:00
Chris Lattner 03507809a0 The new CFrontend generates LOTs of basic blocks that just fall through and do 
other funky stuff.  Clean it up early.

Chris Lattner 82f626e951 Eliminate some compatibility stuff no longer needed :P

Chris Lattner f1257594b5 Reassociate now works 
llvm-svn: 4472
 2002-10-31 17:13:11 +00:00
Chris Lattner 387d76a983 * Remove the -stopraise option, which is no longer needed now that we have 
the -debug-pass=Arguments option
* Run instcombining BEFORE mem2reg so that getelementptr X, long 0's are
  cleaned up.  This is also important because scalar replacement of aggr.
  will want instcombine to run before it goes as well.

llvm-svn: 3879
 2002-09-22 18:50:22 +00:00
Chris Lattner c70222dc15 * No longer need to run die after instcombine 
* Run new correlated expressions pass
* Simplify the CFG (removing dead blocks, merging blocks, eliminating branches
  on constant booleans, etc) after correlated exprs pass.

Chris Lattner 3f5b42697c - Reformat comments 
- 'gccas' puts verifier in logical place in pass procession to avoid
    recomputing dominator information unneccesarily.

Chris Lattner 325c1ce8f3 Run GlobalDCE before deadtypeelim so that we do not retain types for global 
variables that are obviously dead.  The most common case is %FILE
