[PATCH V2] A jump threading opportunity for condition branch

2019-05-28 Thread Jiufu Guo
Hi, This patch implements a new opportunity of jump threading for PR77820. In this optimization, conditional jumps are merged with unconditional jump. And then moving CMP result to GPR is eliminated. This version is based on the proposal of Richard, Jeff and Andrew, and refined to incorporate com
