Separating two consecutive loads can save one cycle on processors with GPR intrelock and can fix load-use on processors that need a load delay slot. Also do so for fwd_fixup. [Ralf: Only R2000/R3000 class processors are lacking the the load-user interlock and even some of those got it retrofitted. With R2000/R3000 being fairly uncommon these days the impact of this bug should be minor.] Signed-off-by: Tony Wu To: linux-mips@linux-mips.org Patchwork: https://patchwork.linux-mips.org/patch/1768/ Signed-off-by: Ralf Baechle --- Reading git-diff-tree failed
