* config/tc-mcore.c (md_pseudo_table): Add .comm for ELF and allow
.section for COFF.
(mcore_s_text): Call obj_elf_text for ELF target.
(mcore_s_data): Call obj_elf_data for ELF target.
(mcore_s_section): No longer ELF specific. Call obj_coff_section
for COFF target.
(mcore_s_bss): New function: Dump literal table before changing
sections.
(mcore_s_comm): New function: Dump literal table before changing
sections.
* config/obj-elf.c (obj_elf_common, obj_elf_data, obj_elf_text):
No longer static functions.
* config/obj-elf.h (obj_elf_common, obj_elf_data, obj_elf_text):
Provide prototypes for these functions.
1999-06-22 Ian Lance Taylor <ian@zembu.com>
* subsegs.c (subseg_text_p): Rewrite non BFD_ASSEMBLER case to use
