Subject: c++: Regenerate cp/cfns.h.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=642dc602f89b2c11d5d833a52f37b04427a27cab;p=gcc.git

c++: Regenerate cp/cfns.h.

Current cfns.h includes register-qualified variables and that wouldn't
play well when bootstrapping with GCC that uses the C++17 dialect,
because 'register' was removed in C++17.  Regenerating it using the
command specified in cfns.h luckily cleaned this up.

	* cfns.h: Regenerated.
