2006-03-01- Added VConstant as an abstract version of ConstantVec.Evan Cheng
- All abstrct vector nodes must have # of elements and element type as their first two operands. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26432 91177308-0d34-0410-b5e6-96231b3b80d8

2006-02-25Added an offset field to ConstantPoolSDNode.Evan Cheng
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26371 91177308-0d34-0410-b5e6-96231b3b80d8
2006-02-18Add checks to make sure we don't create bogus extend nodes, and fix a bugNate Begeman
where we were doing exactly that which was causing failures on x86 and alpha. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26284 91177308-0d34-0410-b5e6-96231b3b80d8
2006-02-17Fix a tricky issue in the SimplifyDemandedBits code where CombineTo wasn'tChris Lattner
exactly the API we wanted to call into. This fixes the crash on crafty last night. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26269 91177308-0d34-0410-b5e6-96231b3b80d8
2006-02-17kill ADD_PARTS & SUB_PARTS and replace them with fancy new ADDC, ADDE, SUBCNate Begeman
and SUBE nodes that actually expose what's going on and allow for significant simplifications in the targets. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26255 91177308-0d34-0410-b5e6-96231b3b80d8
2006-02-09Added SelectionDAG::InsertISelMapEntry(). This is used to workaround the gccEvan Cheng
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). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26094 91177308-0d34-0410-b5e6-96231b3b80d8
2006-02-09More changes to reduce frame size.Evan Cheng
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26083 91177308-0d34-0410-b5e6-96231b3b80d8
2006-02-05* Added SDNode::isOnlyUse().Evan Cheng
* Fix hasNUsesOfValue(), it should be const. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@25990 91177308-0d34-0410-b5e6-96231b3b80d8

2005-12-06Teach the SelectionDAG ISel how to turn ConstantPacked values intoNate Begeman
constant nodes with vector types. Also teach the asm printer how to print ConstantPacked constant pool entries. This allows us to generate altivec code such as the following, which adds a vector constantto a packed float.

2005-12-01Don't remove two operand, two result nodes from the binary ops map. TheseChris Lattner
should come from the arbitrary ops map. This fixes Regression/CodeGen/PowerPC/2005-12-01-Crash.ll git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@24571 91177308-0d34-0410-b5e6-96231b3b80d8
2005-12-01This is a bugfix for SelectNodeTo. In certain situations, we could beChris Lattner
selecting a node and use a mix of getTargetNode() and SelectNodeTo. Because SelectNodeTo didn't check the CSE maps for a preexisting node and didn't insert its result into the CSE maps, we would sometimes miss a CSE opportunity. This is extremely rare, but worth fixing for completeness. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@24565 91177308-0d34-0410-b5e6-96231b3b80d8
