From 2f9046641f748e9a27c97759570dcb983cbab4e9 Mon Sep 17 00:00:00 2001 From: Stephane Carrez Date: Sun, 1 Dec 2002 10:20:06 +0000 Subject: [PATCH] * config/tc-m68hc11.c (elf_flags): Set default ABI to gcc default (32-bit int, 64-bit double). (md_longopts): New options -mshort, -mlong, -mshort-double and -mlong-double to control the ABI. (md_show_usage): Update.
