[Qemu-commits] [COMMIT 14ed7ad] sparc64 flush pending conditional evalua

Subject: [Qemu-commits] [COMMIT 14ed7ad] sparc64 flush pending conditional evaluations beforeexposing cpu state
Date: Mon, 10 Aug 2009 21:48:01 -0000

From: Igor Kovalenko <address@hidden>

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.

Kind regards,
