Dan Gohman 30ff721f09 Fix various doxygen warnings. 
llvm-svn: 96779
 2010-02-22 04:10:52 +00:00
Lang Hames c7ef4cc9fc * Updated the cost matrix normalization proceedure to better handle infinite costs. 
* Enabled R1/R2 application for nodes with infinite spill costs in the Briggs heuristic (made
safe by the changes to the normalization proceedure).
* Removed a redundant header.

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.

Duncan Sands d216b05e75 Mark more constants unsigned, as warned about by icc (#68).

Dan Gohman c7c2bc9663 Remove unnecessary throw() specifications; LLVM doesn't use exceptions.

Daniel Dunbar 4bfb4c80e0 Fix some -Asserts unused variable warnings. 
llvm-svn: 78447

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

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.
