This patch scratches an itch. Each individual gcc command in the
|
||
|
glibc build is over 1K, which means it takes up a good chunk of my
|
||
|
terminal. Most of that is include paths. Any version of GCC new
|
||
|
enough to build glibc supports response files, which were added in
|
||
|
2005. So use a response file for the static list of include paths.
|
||
|
Now the build commands are a lot shorter, and easier to use when
|
||
|
developing glibc.
|
||
|
|
||
|
Tested on x86_64-linux-gnu. Please apply if acceptable.

* Makeconfig (+common-includes): Define.

(+includes): Use @$(common-objpfx)includes.
|
||
|
* Makefile (postclean): Remove includes and includes.mk.
|
||
|
* Makerules ($(common-objpfx)includes.mk): Include and create
|
||
|
includes.mk. Create includes.
