+ * 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.
