* Plug code generator into liveness analysis.Nicolas Geoffray2014-06-101-9/+15
| | | | | | Also implement spill slot support. Change-Id: If5e28811e9fbbf3842a258772c633318a2f4fafc
* Fix some bugs in graph construction/simplification methods.Nicolas Geoffray2014-06-091-7/+8
| | | | | | | | Also fix a brano during SSA construction. The code should not have been commented out. Added a test to cover what the code intends. Change-Id: Ia00ae79dcf75eb0d412f07649d73e7f94dbfb6f0
* Add a linear scan register allocator to the optimizing compiler.Nicolas Geoffray2014-05-261-72/+72
| | | | | | | | | | | | This is a "by-the-book" implementation. It currently only deals with allocating registers, with no hint optimizations. The changes remaining to make it functional are: - Allocate spill slots. - Resolution and placements of Move instructions. - Connect it to the code generator.
