Subject: Eliminate IA-64 compiler warnings.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=0024a8041f8b3a6b02e81632a9fb4b3c61969ac1;p=gcc.git

Eliminate IA-64 compiler warnings.

	* dwarf2out.c (dwarf2out_line): Make last_file_num be unsigned.
	* frame.h (__ia64_personality_v1): Add prototype.
	* libgcc2.c (ia64_throw_helper): Change personality declaration to
	prototype form.  Add void * cast to first argument to personality
	call.
	...

+	prototypes.
+	* config/ia64/ia64.c (emit_insn_group_barriers): Add ATTRIBUTE_UNUSED
+	to dump parameter.
+	(itanium_split_issue): Add prototype.
+	(gen_nop_type): Ifdef out.
+	(find_best_packet): Initialize best_packet.
+	(ia64_encode_section_info): New local string.  Use for ggc_alloc_string
+	result.
+	* config/ia64/ia64.h (ASM_OUTPUT_LONG_DOUBLE): Use 0L not 0.
+	* config/ia64/ia64.md (bsp_value): Add explicit stop bit at start.
