From efac4154711863128558b5b65486ac79b760367e Mon Sep 17 00:00:00 2001 From: Aurelien Jarno Date: Thu, 24 Feb 2011 12:31:41 +0100 Subject: target-sh4: move intr_at_halt out of cpu_halted() All targets except SH4 have the same cpu_halted() routine, and it has only one caller. It is therefore a good candidate for inlining. The difference is the handling of the intr_at_halt, which is necessary to ignore SR.BL when sleeping. Move intr_at_halt handling out of it, by setting this variable while executing the sleep instruction, and clearing it when the CPU has been woken-up by an interrupt, whatever the state of SR.BL. Also rename this variable in_sleep.
