Subject: (g++.o): New target.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=74bb4fdf07bf3d69a886d20654e029916b98359e;p=gcc.git

(g++.o): New target.

(deduced.h): Depend on GCC_PASSES and stmp-int-hdrs.
(xsys-protos.h): Depend on GCC_PASSES.
(fixhdr.ready): New target.
(stmp-fixproto): Depend on fixhdr.ready, not fix-header itself.
(clean): Delete fixhdr.ready.
