X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=02a2c6303f223f529509fffa6ea1ce40054f3e02;p=gcc.git

Minor header reorganization for unordered containers

	* include/bits/hashtable_policy.h: Include <tuple>.
	* include/std/unordered_map: Only include <bits/stl_pair.h> instead
	of <utility> and <tuple>.
	* include/std/unordered_set: Likewise.
