* For PR786:Reid Spencer2006-11-021-1/+0
| | | | | | | | | | Turn on -Wunused and -Wno-unused-parameter. Clean up most of the resulting fall out by removing unused variables. Remaining warnings have to do with unused functions (I didn't want to delete code without review) and unused variables in generated code. Maintainers should clean up the remaining issues when they see them. All changes pass DejaGnu tests and Olden. llvm-svn: 31380

| | | | | | | | | | SelectionDAG and it has since bitrotted. Remove the copy from SelectionDAG. Next, remove the constant folding piece of DAGCombiner::SimplifySetCC into a new FoldSetCC method which can be used by getNode() and SimplifySetCC. This fixes obscure bugs. llvm-svn: 30952
* Fix a bug where we incorrectly turned '(X & 0) == 0' into '(X & 0) >> -1',Chris Lattner2006-10-131-2/+2

| | | | | | the creation of canonical VTLists. llvm-svn: 29709
* Add a new getNode() method that takes a pointer to an already-intern'd listChris Lattner2006-08-141-78/+70
| | | | | | | of value-type nodes. This avoids having to do mallocs for std::vectors of valuetypes when a node returns more than one type. llvm-svn: 29685

* Add code to resize the CSEMap hash table. This doesn't speedup codegen ofChris Lattner2006-08-141-0/+1
| | | | | | kimwitu, but seems like a good idea from a "avoid performance cliffs" standpoint :) llvm-svn: 29675
* Add the actual constant to the hash for ConstantPool nodes. Thanks toChris Lattner2006-08-141-0/+1
| | | | | | Rafael Espindola for pointing this out. llvm-svn: 29669

* eliminate the NullaryOps map, use CSEMap instead.Chris Lattner2006-08-111-22/+18

* Change one ReplaceAllUsesWith method to take an array of operands to replaceChris Lattner2006-08-111-4/+2
| | | | | | instead of a vector of operands. llvm-svn: 29616
* Start eliminating temporary vectors used to create DAG nodes. Instead, passChris Lattner2006-08-081-128/+35
| | | | | | | | | | | | | | | | | | | 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. llvm-svn: 29566
* Eliminate some malloc traffic by allocating vectors on the stack. Change someChris Lattner2006-08-081-61/+44
| | | | | | | | | 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%. llvm-svn: 29561
* Revamp the "CSEMap" datastructure used in the SelectionDAG class. ThisChris Lattner2006-08-071-312/+278
| | | | | | | | | | | 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. llvm-svn: 29550
