Chris Lattner 183661e43a simplify and merge a bunch of code. Instead of comparing against ...

the min/max values for an integer type, compare against the min/max
values we can prove contain the input.  This might be a tighter bound,
so this is general goodness.

ADCE.cpp

Remove the ability for ADCE to remove unreachable blocks in loop nests, because, as Eli pointed out, SimplifyCFG already does this.

GVN.cpp

Use information already present in the ValueTable to fast-fail when we know there won't be a value number match. This speeds up GVN on a case where there are very few redundancies by ~25%.

LoopDeletion.cpp

Use use_empty() instead of getNumUses(), avoiding a use list traversal.

LoopIndexSplit.cpp

If loop induction variable's start value is less then its exit value then do not split the loop.

LoopUnroll.cpp

Preserve dom info.

2008-07-03 07:04:22 +00:00

LoopUnswitch.cpp

Do not try to update dominator info while manipulating CFG. This code does not handle all cases and keeps invalid dom info around some cases, which misleads other passes down stream.
