* read.h (mri_comon_symbol): Declare. (s_mri_common): Declare. * read.c (mri_line_label): New static variable. (mri_common_symbol): New global variable. (potable): Add "common" and "common.s". (read_a_source_file): In MRI mode, set mri_line_label for a label at the start of a line. (s_mri_common): New function. (s_space): Handle mri_common_symbol. * symbols.c (colon): Change return value from void to symbolS *, and return new symbol. If mri_common_symbol is set, attach the new symbol to it. (resolve_symbol_value): Handle an sy_mri_common symbol. * symbols.h (colon): Change return value in declaration. * subsegs.c (subseg_set_rest): Clear mri_common_symbol. (subseg_set (both versions)): Likewise. * frags.c (frag_more): Warn if mri_common_symbol is not NULL. * write.c (adjust_reloc_syms): Skip sy_mri_common symbols. (write_object_file): Discard sy_mri_common symbols. (fixup_segment): Change relocations against sy_mri_common symbols to be against the common symbol itself. * config/obj-coff.c (yank_symbols): Discard sy_mri_common symbols. (fixup_segment): Change relocations against sy_mri_common symbols to be against the common symbol itself. * config/obj-aout.c (obj_crawl_symbol_chain): Discard sy_mri_common symbols.
