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 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.

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.

from LoopSimplify.cpp to Dominator.cpp

 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.

Devang Patel cf470e5255 Do not use ETForest as well as DomiantorTree. DominatorTree is sufficient. 
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: 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

Owen Anderson f35a1dbc7a Remove ImmediateDominator analysis. The same information can be obtained from DomTree. A lot of code for 
constructing ImmediateDominator is now folded into DomTree construction.

This is part of the ongoing work for PR217.
