      gcc/ChangeLog:

	PR middle-end/78622
	PR middle-end78606
	* gimple-ssa-sprintf.c (min_bytes_remaining): Use res.knownrange
	rather than res.bounded.
	(get_width_and_precision): Set precision to -1 when negative.
	(adjust_range_for_overflow): New function.
	(format_integer): Correct the handling of the space, plus, and pound
	flags, and the special case of zero precision.

	is specified and unknown.
	Call adjust_range_for_overflow.
	Avoid use zero as the shortest value when precision is specified
	but unknown.
	(format_directive): Remove vestigial quoting.  Always inform of
	argument value or range when it's available.
