Alkis Evlogimenos 84f5bcb013 Change the way we choose a free register: instead of picking the first ... free allocatable register, we prefer the a free one with the most uses of inactive intervals. This causes less spills and performes a bit better compared to gcc: Program | GCC/LLC (Before)| GCC/LLC (After) 164.gzip/164.gzip | 0.59 | 0.60 175.vpr/175.vpr | 0.57 | 0.58 176.gcc/176.gcc | 0.59 | 0.61 181.mcf/181.mcf | 0.94 | 0.95 186.crafty/186.crafty | 0.62 | 0.62 197.parser/197.parser | 0.89 | 0.88 252.eon/252.eon | 0.61 | 0.66 253.perlbmk/253.perlbmk | 0.79 | 0.84 254.gap/254.gap | 0.81 | 0.81 255.vortex/255.vortex | 0.92 | 0.93 256.bzip2/256.bzip2 | 0.69 | 0.69 300.twolf/300.twolf | 0.91 | 0.90 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@16147 91177308-0d34-0410-b5e6-96231b3b80d8		2004-09-02 21:23:32 +00:00
