[Qemu-devel] [PATCH] target-arm/helper.c: tb_flush() on CPU reset


From: Peter Maydell
Subject: [Qemu-devel] [PATCH] target-arm/helper.c: tb_flush() on CPU reset
Date: Wed, 1 Feb 2012 17:23:04 +0000

Since target-arm has some CPUState fields for which we take the approach
of baking assumptions about them into translated code and then calling
tb_flush() when the fields change, we must also tb_flush on CPU reset,
because reset is a change of those fields.
