Chris Lattner 0f39359dd2 Add a new pass

Chris Lattner 69e896bdcf Make sure to print a stack trace whenever an error signal is delivered to 
the tool.

Chris Lattner eddfe437c7 Now that tailduplication does not bork SSA form, run mem2reg earlier in gccas. 
This tremendously improves the code generated by the LLVM optimizer, primarily
by making the inliner more aggressive.  For example, it improves the stepanov
benchmark from 55.56 mega-additions/sec to 98.04 Ma/s.  It also improves the
oopack/iterator benchmark from 338.3MFLOPS/s to 1103.4MFLOPS/s.  Less noteworthy,
it improves oopack/matrix from 573 -> 641 MFLOPS/s.

Chris Lattner 298d2f090f Make sure to verify the result before writing out the bytecode file. Not doing 
so can cause obscure errors downstream.

Chris Lattner cf1755a6f3 Add a -disable-opt flag to gccas, so that we can use -Wa,-disable-opt just 
like -Wl,-disable-opt

Chris Lattner b762ddbdf1 It is now after pldi. This issue has been fixed, so remove the hack

Chris Lattner db8a179838 Revert the previous patch since it causes lots of miscompilations. :( :(

Chris Lattner 52b4fb3fde Reorder passes a bit. In particular, it makes sense to run globaldce IMMEDIATELY after funcresolve. Also, run the mem2reg pass _early_ so that IPCP and DAE actually do stuff. 
Run instcombine and simplify cfg after this to cleanup the intraprocedural messes we create.

Chris Lattner 093cc6dc92 As the comments indicate, this is a temporary, repulsive, hack

Chris Lattner 3f8b7c24f6 Unfortunately, it looks like level raise is still needed :( 
llvm-svn: 9158

Chris Lattner 3334c884bc Give this file a proper header 
llvm-svn: 9141
 2003-10-15 21:49:57 +00:00
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 b8f72991a6 Completely remove mention of the correlated branch elimination pass. It has 
bugs and needs to be reworked anyway.

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 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
Vikram S. Adve 9c485d2165 gcc3.1.1 seems much more selective about what it loads from archives, and 
does not link in many passes that are loaded by gcc2.95.3.  So use object
files instead of archives in many more cases.

llvm-svn: 3803
 2002-09-18 02:20:58 +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.
