Dan Gohman e7a243fea5 Add a new ObjC ARC optimization pass to eliminate unneeded 
autorelease push+pop pairs.

llvm-svn: 148330
 2012-01-17 20:52:24 +00:00
Rafael Espindola a45c20b049 Remove the old tail duplication pass. It is not used and is unable to update 
ssa, so it has to be run really early in the pipeline. Any replacement
should probably use the SSAUpdater.

Rafael Espindola 7281395c8c Add LLVMAddLowerExpectIntrinsicPass to the C API.

Dan Gohman 06d70015ce Delete the GEPSplitter experiment.

 2011-02-28 19:47:47 +00:00
Dan Gohman b8a25f49f3 Delete the SimplifyHalfPowrLibCalls pass, which was unused, and 
only existed as the result of a misunderstanding.

Cameron Zwarich 4694e69540 Remove outdated references to dominance frontiers.

Chris Lattner 9987a6f49b split SROA into two passes: one that uses DomFrontiers (-scalarrepl) 
and one that uses SSAUpdater (-scalarrepl-ssa)

Cameron Zwarich cab9a0abab Add a new loop-instsimplify pass, with the intention of replacing the instance 
of instcombine that is currently in the middle of the loop pass pipeline. This
commit only checks in the pass; it will hopefully be enabled by default later.

Chris Lattner 704541bb23 sketch out a new early cse pass. No functionality yet.

No functionality yet.

Devang Patel 57da4caa85 Remove LoopIndexSplit pass. It is neither maintained nor used by anyone. 
llvm-svn: 116004
 2010-10-07 23:29:37 +00:00
Owen Anderson 4698c5d7f7 Next step on the getting-rid-of-static-ctors train: begin adding per-library 
initialization functions that initialize the set of passes implemented in
that library.  Add C bindings for these functions as well.
