+ * config.gcc (mips-sgi-irix6*): Add t-iris6gld to tmake_file when
+ using GNU ld.
+ * config/mips/iris6.h (IRIX6_STARTFILE_SPEC): New, taking the
+ whole of the previous STARTFILE_SPEC except crtbegin.o%s.
+ (IRIX6_ENDFILE_SPEC): Likewise ENDFILE_SPEC and crtend.o%s.
+ (STARTFILE_SPEC, ENDFILE_SPEC): Define in terms of the above.
+ (SUBTARGET_EXTRA_SPECS): Define.
+ * config/mips/iris6gld.h (LINK_SPEC): Change -init function
+ to __gcc_init and -fini function to __gcc_fini.
+ (STARTFILE_SPEC): Redefine, including irix6-crti.o before crtbegin.o.
+ (ENDFILE_SPEC): Likewise, including irix6-crtn.o after crtend.o.
+ (INIT_SECTION_ASM_OP, FINI_SECTION_ASM_OP): Define.
+ * config/mips/t-iris6gld,
+ * config/mips/irix6-crti.asm,
+ * config/mips/irix6-crtn.asm: New files.
