2006-08-14Add a new getNode() method that takes a pointer to an already-intern'd listChris Lattner
of value-type nodes. This avoids having to do mallocs for std::vectors of valuetypes when a node returns more than one type. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@29685 91177308-0d34-0410-b5e6-96231b3b80d8

2006-08-14Add code to resize the CSEMap hash table. This doesn't speedup codegen ofChris Lattner
kimwitu, but seems like a good idea from a "avoid performance cliffs" standpoint :) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@29675 91177308-0d34-0410-b5e6-96231b3b80d8

2006-08-11eliminate the NullaryOps map, use CSEMap instead.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@29621 91177308-0d34-0410-b5e6-96231b3b80d8
2006-08-11Change one ReplaceAllUsesWith method to take an array of operands to replaceChris Lattner
instead of a vector of operands. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@29616 91177308-0d34-0410-b5e6-96231b3b80d8
2006-08-08Start eliminating temporary vectors used to create DAG nodes. Instead, passChris Lattner
in the start of an array and a count of operands where applicable. In many cases, the number of operands is known, so this static array can be allocated on the stack, avoiding the heap. In many other cases, a SmallVector can be used, which has the same benefit in the common cases. I updated a lot of code calling getNode that takes a vector, but ran out of time. The rest of the code should be updated, and these methods should be removed. We should also do the same thing to eliminate the methods that take a vector of MVT::ValueTypes. It would be extra nice to convert the dagiselemitter to avoid creating vectors for operands when calling getTargetNode. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@29566 91177308-0d34-0410-b5e6-96231b3b80d8
2006-08-08Eliminate some malloc traffic by allocating vectors on the stack. Change someChris Lattner
method that took std::vector<SDOperand> to take a pointer to a first operand and #operands. This speeds up isel on kc++ by about 3%. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@29561 91177308-0d34-0410-b5e6-96231b3b80d8
2006-08-07Revamp the "CSEMap" datastructure used in the SelectionDAG class. ThisChris Lattner
eliminates a bunch of std::map's in the SelectionDAG, replacing them with a home-grown hashtable. This is still a work in progress: not all the maps have been moved over and the hashtable never resizes. That said, this still speeds up llc 20% on kimwitu++ with -fast -regalloc=local using a release build. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@29550 91177308-0d34-0410-b5e6-96231b3b80d8
