Subject: format.c (parse_format_list): Set repeat count for P descriptors.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=d809264e863ffbf312af0e23bd30799ffa999096;p=gcc.git

format.c (parse_format_list): Set repeat count for P descriptors.

	* io/format.c (parse_format_list): Set repeat count for P descriptors.
	* write.c (output_float): Fix condition.  Correctly handle nonzero
	scale factor.
