Subject: (do_spec_1): Add %u.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=d887e8089bcfb74cd4dc365603550b2d793b0009;p=gcc.git

(do_spec_1): Add %u.

	(default_compilers): For output of as when -c is not used, use %u
	rather than %g so each object filename will be unique.

(NULL_PTR): Use the same definition as
	rtl.h and tree.h.
