From 4f3f8e94b7b079131f0faf641e8afd790a6537d1 Mon Sep 17 00:00:00 2001 From: David Howells Date: Mon, 14 Apr 2008 11:20:59 +0100 Subject: [PATCH] FRV: Correctly determine the address of an illegal instruction Correctly determine the address of an illegal instruction. The EPCR0 register holds this value (masked by EPCR0_PC) if the validity bit is set (masked by EPCR0_V). So the test as to whether the contents of the register are usable should be involve checking the _V bit, not the _PC bits.
