From 3eb9b25ae5d2bcc024646c5a04f28899661ab14c Mon Sep 17 00:00:00 2001 From: Blue Swirl Date: Sun, 2 Sep 2012 07:33:31 +0000 Subject: [PATCH] target-s390x: split FPU ops Move floating point instructions to fpu_helper.c. While exporting some condition code helpers, avoid duplicate identifier conflict with translate.c. Remove unused set_cc_nz_f64() in translate.c.
