From b9369a384b10c934daab9de64fbff80b3659d837 Mon Sep 17 00:00:00 2001 From: Igor Kovalenko Date: Wed, 29 Jul 2009 01:32:23 +0400 Subject: 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.
