| * | Add the Optimize Compares pass (disabled by default). | Bill Wendling | 2010-08-06 | 1 | -0/+112 |
| 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. llvm-svn: 110423 | |||||
