* config/sparc/tm-sp64.h (CALL_DUMMY): Store and retrieve

Browse Source 
%o0-%o5 as 64-bit values; compensate for stack bias.
	(USE_STRUCT_CONVENTION): We only pass pointers to structs
	if they're larger than 32 bytes.
	(REG_STRUCT_HAS_ADDR): Ditto.

	* sparc-tdep.c (sparc_init_extra_frame_info): Use read_sp()
 	instead of read_register. If the target is a sparc64 and the frame
 	pointer is odd, compensate for the stack bias.
	(get_saved_register): Use read_sp().
	(DUMMY_STACK_REG_BUF_SIZE): Use FP_REGISTER_BYTES.
	(sparc_push_dummy_frame): Use read_sp()/write_sp(). On sparc64,
 	save the PC, NPC, CCR, FSR, FPRS, Y and ASI registers.
	(sparc_frame_find_saved_regs): Use read_sp(). Read the PC, NPC,
 	CCR, FSR, FPRS, Y and ASI registers from the frame, if it's a
 	dummy frame.
	(sparc_pop_frame): Use write_sp(). If the target is a sparc64 and
 	the FP is odd, compensate for stack bias.
	(sparc_store_return_value): Right-justify the return value before
 	writing it to %o0.
	(sparc_fix_call_dummy): Don't NOP out part of the call dummy on
 	sparc64.
	(sparc64_read_sp, sparc64_read_fp, sparc64_write_sp,
 	sparc64_write_fp, sp64_push_arguments,
 	sparc64_extract_return_value): New functions to support the
 	sparc64 ABI.

	* dwarfread.c (handle_producer): Set processing_gcc_compilation to
 	the right version number.

	* dwarf2read.c (read_file_scope): Assume we're processing
	GCC2 output.
