From 8c5c99dc2241ea323cee1b07ec5466387dfb983f Mon Sep 17 00:00:00 2001 From: Maxim Kuvyrkov Date: Tue, 18 Sep 2007 11:40:04 +0000 Subject: [PATCH] m68k-devices.def (51qe): New device. * config/m68k/m68k-devices.def (51qe): New device. * config/m68k/m68k.c (FL_FOR_isa_c): Remove division unit. Add it to all uses of FL_FOR_isa_c for compatibility. (all_microarchs): Add cfv1 microarchitecture. (m68k_handle_option): Handle m51qe option. * config/m68k/m68k.h (TARGET_CPU_CPP_BUILTINS): Handle 51QE. (TUNE_CFV1): New macro. (enum uarch_type): Add ucfv1. * doc/invoke.texi: Document 51qe device and cfv1 microarchitecture.
