Lang Hames	090c7e82dd	New PBQP solver. ... * Fixed a reduction bug which occasionally led to infinite-cost (invalid) register allocation solutions despite the existence finite-cost solutions. * Significantly reduced memory usage (>50% reduction). * Simplified a lot of the solver code. llvm-svn: 94514	2010-01-26 04:49:58 +00:00
Lang Hames	68dd9c7dd7	Fixed malformed -*- lines in PBQP headers. ... llvm-svn: 92830	2010-01-06 08:53:34 +00:00
Lang Hames	8f0d67536e	Added legal stuff, fixed some formatting issues. Removed the graph generator stuff as it was only meant for debugging the solver. ... llvm-svn: 78359	2009-08-07 00:25:12 +00:00
Lang Hames	88fae6f9c9	New C++ PBQP solver. Currently about as fast (read _slow_) as the old C based solver, but I'll be working to improve that. The PBQP allocator has been updated to use the new solver. ... llvm-svn: 78354	2009-08-06 23:32:48 +00:00
