* Switch from defaulting to the 'local' spiller to the 'simple' spiller. TheChris Lattner2004-09-301-2/+2
| | | | | | | | | | two spillers produce perfectly identical code (at least on povray and eon), but the simple spiller is substantially faster than the local spiller. Once the local spiller is improved, we can switch back. Switching cuts 5.2% off of the llc time for povray (about 1.3s). llvm-svn: 16608
* Don't use a densemap for keeping track of which vregs are already loaded, justChris Lattner2004-09-301-6/+10
| | | | | | | use a simple vector. This speeds up -spiller=simple from taking 22s to taking .1s on povray (debug build). This change does not modify the generated code. llvm-svn: 16607
* Use longer and more explicit names for instance vars (particularly importantChris Lattner2004-09-301-32/+30
| | | | | | | data structures). Fix the print method to send to the right ostream, not always cerr. Delete typedefs that are only used once. llvm-svn: 16606
* Reindent code, improve comments, move huge nested methods out of classes,Chris Lattner2004-09-301-300/+314
