From 14ed7adc1b14597741ac6f9bb64ca23ac26b3f2a Mon Sep 17 00:00:00 2001 From: Igor Kovalenko Date: Wed, 29 Jul 2009 01:32:23 +0400 Subject: [PATCH] sparc64 flush pending conditional evaluations before exposing cpu state If translation block is interrupted by e.g. mmu exception we need to compute conditional flags for inclusion into saved cpu state. Otherwise after return from trap conditional instructions would use stale psr/xcc data. Signed-off-by: igor.v.kovalenko@gmail.com -- Kind regards, Igor V.
