This speeds up the + rest of compilation and slightly improves the result of register + allocation when register pressure is high. + +- Implemented a spilling heuristic during register allocation. + This heuristic reduces significantly the amount of spill code + generated when register pressure is high. + +- Implemented aggressive coalescing between pairs of spilled variables. + + Release 1.7.1, 2010-04-13 ========================= @@ -190,7 +214,6 @@ Release 1.3, 2008-08-11 - More benchmark programs in test/ - Release 1.2, 2008-04-03 ======================= |
