[PATCH] D111034: [AArch64] Optimize add/sub with immediate

[Ben Shi via Phabricator via llvm-commits]

benshi001 added inline comments.


================
Comment at: llvm/lib/Target/AArch64/AArch64MIPeepholeOpt.cpp:146
-
-  if (SubregToRegMI && !MRI->hasOneUse(SubregToRegMI->getOperand(0).getReg()))
     return false;
----------------
These code from line 122 - 146 will be used by both `visitAND` and `visitADDSUB`, so I moved them to a new function `AArch64MIPeepholeOpt::checkMovImmInstr` with little modification.
