* Transpose the calculation of spill weights such that we are calculating oneJakob Stoklund Olesen2010-08-103-1/+41
| | | | | | | | | | | | | | 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@110631 91177308-0d34-0410-b5e6-96231b3b80d8

* Add the Optimize Compares pass (disabled by default).Bill Wendling2010-08-062-0/+19
| | | | | | | | | | | | | | | | | This pass tries to remove comparison instructions when possible. For instance, if you have this code: sub r1, 1 cmp r1, 0 bz L1 and "sub" either sets the same flag as the "cmp" instruction or could be converted to set the same flag, then we can eliminate the "cmp" instruction all together. This is a important for ARM where the ALU instructions could set the CPSR flag, but need a special suffix ('s') to do so. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@110423 91177308-0d34-0410-b5e6-96231b3b80d8
