Kang Zhang	d37befdfe5	[PowerPC] Remove the redundant implicit operands in ppc-early-ret pass ... Summary: In the `ppc-early-ret` pass, we have use `BuildMI` and `copyImplicitOps` when the branch instructions can do the early return. But the two functions will add implicit operands twice, this is not correct. This patch is to remove the redundant implicit operands in `ppc-early-ret pass`.

Kang Zhang	782a4dd1a4	[PowerPC] Use add instead of addReg in ppc-early-ret pass ... Summary: The ppc-early-ret pass use the addReg() to add operand to the new instruction, it can't reserve the flag of old operand. This has caused machine verfications failed. This patch use add() to instead of addReg(). Reviewed By: steven.zhang Differential Revision: https://reviews.llvm.org/D77997	2020-05-13 05:59:52 +00:00
