Devang Patel e3206cb425 Use SmallPtrSet. 
llvm-svn: 40560
 2007-07-27 18:34:27 +00:00
Dan Gohman 6e853bc73f Move the GET_SIDE_EFFECT_INFO logic from isInstructionTriviallyDead 
to Instruction::mayWriteToMemory, fixing a FIXME, and helping
various places that call mayWriteToMemory directly.

Devang Patel 33227115b9 Add BasicInliner interface.

level call graph information.:wq

Devang Patel 186e0d8b0a After a basic block is split into two parts, 
second part dominates all the blocks dominated
by original basic block. And first part dominates
second part.

Devang Patel de5901523c Now this temp. fix is not required. 
llvm-svn: 40034
 2007-07-19 02:22:21 +00:00
Reid Spencer 3363f4ad96 Return Undef if the block has no dominator. This was required to allow 
llvm-gcc build to succeed. Without this change it fails in libstdc++
compilation. This causes no regressions in dejagnu tests. However, 
someone who knows this code better might want to review it.

llvm-svn: 39924

llvm-svn: 37540
 2007-06-11 21:18:00 +00:00
Devang Patel becc466451 Update LoopSimplify to require and preserve DominatorTree only. 
Now LoopSimplify does not require nor preserve ETForest.

llvm-svn: 37512

llvm-svn: 37501
 2007-06-07 22:17:16 +00:00
Devang Patel fc7fdef7d2 Use DominatorTree instead of ETForest. 
This allows faster immediate domiantor walk.

llvm-svn: 37500
 2007-06-07 21:57:03 +00:00
Devang Patel af41e4a192 Maintain ETNode as part of DomTreeNode.

llvm-svn: 36662
 2007-05-03 01:11:54 +00:00
Devang Patel e95c6ad802 Use 'static const char' instead of 'static const int'. 
Due to darwin gcc bug, one version of darwin linker coalesces
static const int, which defauts PassID based pass identification.

llvm-svn: 36652

Chris Lattner 430c9217f0 redesign the primary datastructure used by mem2reg to eliminate an

Chris Lattner c85e79f3e0 With the last change, we no longer need both directions of mapping from 
BBNumbers.  Instead of using a bi-directional mapping, just use a single

1.2485s.

Reid Spencer 3aaaa0b2bd For PR411: 
This patch replaces the SymbolTable class with ValueSymbolTable which does
not support types planes. This means that all symbol names in LLVM must now
be unique. The patch addresses the necessary changes to deal with this and
removes code no longer needed as a result. This completes the bulk of the
changes for this PR. Some cleanup patches will follow.
