5fe1f54c17 Significantly improve handling of vectors that are live across basic blocks, 
handling cases where the vector elements need promotion, expansion, and when
the vector type itself needs to be decimated.

672a42d731 Add a hacky workaround for crashes due to vectors live across blocks. 
Note that this code won't work for vectors that aren't legal on the
target.  Improvements coming.

abac61603f Add checks to make sure we don't create bogus extend nodes, and fix a bug 
where we were doing exactly that which was causing failures on x86 and
alpha.

375e1a71cc Fix a tricky issue in the SimplifyDemandedBits code where CombineTo wasn't 
exactly the API we wanted to call into.  This fixes the crash on crafty last
night.

5965bd19f8 kill ADD_PARTS & SUB_PARTS and replace them with fancy new ADDC, ADDE, SUBC 
and SUBE nodes that actually expose what's going on and allow for
significant simplifications in the targets.

a1ef3ec5b5 Added SelectionDAG::InsertISelMapEntry(). This is used to workaround the gcc 
problem where it inline the map insertion call too aggressively. Before this
change it was producing a frame size of 24k for Select_store(), now it's down
to 10k (by calling this method rather than calling the map insertion operator).

llvm-svn: 26094

d3f1db93c1 More changes to reduce frame size. 
Move all getTargetNode() out of SelectionDAG.h into SelectionDAG.cpp. This
prevents them from being inlined.
Change getTargetNode() so they return SDNode * instead of SDOperand to prevent
copying. It should also help compilation speed.

llvm-svn: 26083
 2006-02-09 07:15:23 +00:00

d37645c07d * Added SDNode::isOnlyUse(). 
* Fix hasNUsesOfValue(), it should be const.
