Chris Lattner 3562ea84ab Implement a FIXME, improving the efficiency of DSA on povray. 
This reduces CBU time from 145s -> 122s (debug build), reduces # allocated nodes
from 129420 to 116477.

Chris Lattner 536b131c9c Fix BU datastructures with povray! 
The problem was that we were merging a field of a node with a value that was
deleted.  Thanks to bugpoint for reducing povray to a nice small 3 function
example.  :)

 2004-03-04 17:06:53 +00:00
Chris Lattner 8db52980b7 Minor changes, remove some debugging code that got checked in somehow. 
Make sure to scope the NodeMap passed into cloneInto so that it doesn't point
to nodes that are deleted.  Add some FIXME's for future performance enhancements.

 2004-03-04 04:37:22 +00:00
Chris Lattner f48eb7519a Only clone nodes that are needed in the caller, don't clone ALL aux calls. This improves 
povray from having ~600K nodes and 300K call nodes to 65K nodes and 25K call nodes.

llvm-svn: 12105
 2004-03-03 23:00:19 +00:00
Chris Lattner d9da2678fc Fix a DSA bug that caused DSA to generate incredibly huge graphs and take forever to 
do it on povray.  The problem is that we were not copying globals from callees to
callers unless the existed in both graphs.  We should have copied them in the case
where the global pointed to a node that was copied as well.

Brian Gaeke 015972103d Make MachineOperand's value named 'contents'. Make really, really sure 
it is always completely initialized and copied.
Also, fix up many comments and asserts.

Chris Lattner 140b2cbd28 Fix a node mapping problem that was causing the pool allocator to locally allocate 
nodes that were globally live, thus breaking programs.

Chris Lattner 93e9878c2c SPECIFY a target data to initialize the CBE target with. Until now we have 
been using the default target data layout object to lower malloc instructions,
causing us to allocate more memory than we needed!  This could improve the
performance of the CBE generated code substantially!

llvm-svn: 12088

Alkis Evlogimenos 31953c7a10 Add a spiller option to llc. A simple spiller will come soon. When we get CFG in the machine code represenation a global spiller will also be possible. Also document the linear scan register allocator but mark it as experimental for now.
