Chris Lattner 5892d47a62 Change the use_list to be a smallvector instead of a vector. This reduces
isel time from 6.79s to 5.53s (22%) on kc++ with a release build on ppc.
Go smallvector! :)

Chris Lattner 2fa6d3b1fc Add a new getNode() method that takes a pointer to an already-intern'd list
of value-type nodes.  This avoids having to do mallocs for std::vectors of
valuetypes when a node returns more than one type.

Chris Lattner bd564bfc63 Start eliminating temporary vectors used to create DAG nodes. Instead, pass
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.

Chris Lattner f06f35e30b Eliminate some malloc traffic by allocating vectors on the stack. Change some
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%.

2006-08-07 23:31:24 +00:00
Chris Lattner a5682853b9 Revamp the "CSEMap" datastructure used in the SelectionDAG class. This
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.
