Subject: 	* 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. 	(md_parse_option): Handle new options. 	*
 doc/as.texinfo (Overview): Document new options for HC11/HC12.
