* config/sparc/sparc.h (REGNO_OK_FOR_{INDEX,BASE,FP,CCFP}_P):

	Explicitly mark the constant being compared against as unsigned.
	* config/sparc/sparc.c (sparc_select, cpu_default, cpu_table):
	Fully initialize final members.
	(mem_aligned_8): Explicit init of offset to zero.
	(output_function_prologue): Explicit init of n_regs to zero.
	(output_function_epilogue): Likewise, and mark arg size as
	unused.

	(function_arg_pass_by_reference): Likewise for cum and named.
	(sparc_builtin_saveregs): Likewise for arglist.
