Daniel Dunbar 21e9834bc1 MC: Stop restarting layout on every relaxation. ... - Still O(N^2), just a faster form, and now its the MCAsmLayout's fault. On the .s I am tuning against (combine.s from 403.gcc): -- ddunbar@lordcrumb:MC$ diff stats-before.txt stats-after.txt 5,10c5,10 < 1728 assembler - Number of assembler layout and relaxation steps < 7707 assembler - Number of emitted assembler fragments < 120588 assembler - Number of emitted object file bytes < 2233448 assembler - Number of evaluated fixups < 1727 assembler - Number of relaxed instructions < 6723845 mcexpr - Number of MCExpr evaluations --- > 3 assembler - Number of assembler layout and relaxation steps > 7707 assembler - Number of emitted assembler fragments > 120588 assembler - Number of emitted object file bytes > 14796 assembler - Number of evaluated fixups > 1727 assembler - Number of relaxed instructions > 67889 mcexpr - Number of MCExpr evaluations -- Feel free to LOL at the -before numbers, if you like. I am a little surprised we make more than 2 relaxation passes. It's pretty trivial for us to do relaxation out-of-order if that would give a speedup. llvm-svn: 99543		2010-03-25 19:35:56 +00:00
