egcs-19980608: General warning fixes patch
- To: egcs-patches at cygnus dot com
- Subject: egcs-19980608: General warning fixes patch
- From: "Kaveh R. Ghazi" <ghazi at caip dot rutgers dot edu>
- Date: Fri, 12 Jun 1998 10:31:30 -0400 (EDT)

* Makefile.in (c-lang.o): Depend on output.h.
* c-lang.c: Include output.h.
* sparc.c (sparc_builtin_saveregs): Remove unused variable `fntype'.
* except.c (expand_builtin_eh_stub): Likewise for variable `jump_to'.
* genrecog.c (write_subroutine): When writing insn-recog.c, mark
variables `insn', `pnum_clobbers', `x[0 .. max_depth]' and `tem'
with ATTRIBUTE_UNUSED.
* reload1.c Include hard-reg-set.h before rtl.h to get macro
HARD_CONST. Include machmode.h before hard-reg-set.h.
* rtl.h: Prototype `retry_global_alloc' and wrap with macro
HARD_CONST to protect usage of typedef HARD_REG_SET.
* tree.c: Prototype `_obstack_allocated_p'.
* varasm.c: Wrap prototype of `asm_output_aligned_bss' in macro
BSS_SECTION_ASM_OP.
