* subsegs.c (subseg_new): Set output_section of new section. * as.c (perform_an_assemly_pass): Don't set output_section here. * expr.c (expr_part, expr): Turn off section assertions for ECOFF, since it has additional sections. * read.c (s_lcomm): For MIPS ECOFF, put small objects in .sbss, not bss_section. * config/obj-ecoff.h (TARGET_SYMBOL_FIELDS): Added ecoff_undefined field. * config/obj-ecoff.c (obj_symbol_new_hook): Initialize ecoff_undefined field. (add_file): If using stabs, just output a stabs symbol rather than creating a new fdr. (obj_ecoff_begin, obj_ecoff_bend): Ignore line number by reading it with get_absolute_expression, rather than skipping it by hand. (obj_ecoff_loc): If using stabs, just output a stabs symbol rather than ECOFF line number information. (obj_ecoff_stab): Accept non-zero values for stabs line number. (ecoff_build_symbols): Set ifilesym correctly. Set storage class to small, undefined and/or readonly sections if appropriate. Don't output symbol names containing \001 characters. (ecoff_frob_file): Make sure at least one fdr is output. * config/tc-mips.h: Define TC_MIPS. * config/tc-mips.c (g_switch_value): New static variable. (md_assemble): Set gp size of output BFD. (gp_reference): New function; returns 1 if expression can be accesssed via gp. Always returns 0 if not using ECOFF. (macro_build): Convert BFD_RELOC_LO16 to BFD_RELOC_MIPS_GPREL if possible. (macro): Generate sequences using gp if possible. (md_parse_option): Ignore -EL and -EB. Parse -G. (md_apply_fix): Added BFD_RELOC_MIPS_GPREL to ignored case. (s_change_sec): Handle .rdata and .sdata for ECOFF. (s_extern): Mark symbol as external. Set ecoff_undefined field.
