Jakob Stoklund Olesen 1ab2fab3af Transpose the calculation of spill weights such that we are calculating one ... register at a time. This turns out to be slightly faster than iterating over instructions, but more importantly, it allows us to compute spill weights for new registers created after the spill weight pass has run. Also compute the allocation hint at the same time as the spill weight. This allows us to use the spill weight as a cost metric for copies, and choose the most profitable hint if there is more than one possibility. The new hints provide a very small (< 0.1%) but universal code size improvement. llvm-svn: 110631		2010-08-10 00:02:26 +00:00
