Subject: Mark ld.so internel __profile_frequency hidden
X-Git-Tag: glibc-2.23~328
X-Git-Url: https://sourceware.org/git/?a=commitdiff_plain;h=e19f02428bacdf7565cb4e61a363c61501ce6870;p=glibc.git

Mark ld.so internel __profile_frequency hidden

Since ld.so internel __profile_frequency is only used internally in
ld.so, it can be made hidden.

	[BZ #19122]
	* include/libc-internal.h [IS_IN (rtld)] (__profile_frequency):
	Add attribute_hidden.
