From 0365f707c99bf940a51c2a3ffc19f3ade2f700d4 Mon Sep 17 00:00:00 2001 From: Jesper Nilsson Date: Tue, 21 Oct 2008 22:10:27 +0200 Subject: [CRIS] Merge asm-offsets.c for both arches into one file. Eliminates the link to arch specific asm-offsets.c from CRIS architecture build system. Resulting asm-offsets.s are identical before and after change for both arch-v10 and arch-v32.
