kbuild: Add __cc-option macro

2018-11-23T07:20:35Z

commit 9f3f1fd299768782465cb32cdf0dd4528d11f26b upstream. cc-option uses KBUILD_CFLAGS and KBUILD_CPPFLAGS when it determines whether an option is supported or not. This is fine for options used to build the kernel itself, however some components like the x86 boot code use a different set of flags. Add the new macro __cc-option which is a more generic version of cc-option with additional parameters. One parameter is the compiler with which the check should be performed, the other the compiler options to be used instead KBUILD_C*FLAGS. Refactor cc-option and hostcc-option to use __cc-option and move hostcc-option to scripts/Kbuild.include.

kbuild: handle the dependency of multi-objs hostprogs appropriately

2014-08-19T08:26:20Z

Assume we have a Makefile like: hostprogs-y := foo bar foo-objs := foo1.o foo2.o bar-objs := bar1.o bar2.o Without this commit, the host program foo depends on all of foo1.o foo2.o bar1.o bar2.o. This commit allows to handle the dependency of each host program separately. Signed-off-by: Masahiro Yamada Signed-off-by: Michal Marek

kbuild: clean-up and bug fix of scripts/Makefile.host

2014-07-16T15:15:26Z

Assume we have a Makefile like this: hostprogs-y := foo foo-cxxobjs := bar/baz.o foo-objs := qux/quux.o In this case, Kbuild creates bar/ directory, but fails to create qux/ directory. This commit re-writes directory creation more simply, fixing that bug. Signed-off-by: Masahiro Yamada Signed-off-by: Michal Marek

kbuild: clean up scripts/Makefile.host

2014-07-16T15:15:26Z

The directory creation can be more simplified by two levels. [1] Drop $(dir ...) $(dir $(f)) always returns non-empty string. So, $(if $(dir $(f)),$(dir $(f)) is equivalent to $(dir $(f)). [2] Unroll $(foreach ...) loop $(dir ...) can take one or more arguments and returns a list of directories of them. $(foreach f, $(progs), $(dir $(f))) can be unrolled as $(dir $(progs)).

kbuild: drop shared library support from Makefile.host

2014-07-16T15:15:26Z

The shared library feature in Makefile.host is no longer used. Rip it off to keep the build infrastucture simple. Update Documentation/kbuild/makefiles.txt too. The section "4.3 Definition shared libraries" should be removed and the following sections should be re-numbered.

kbuild: fix a bug of C++ host program handling

2014-07-16T15:15:25Z

The comment claims: C++ executables compiled from at least one .cc file and zero or more .c files But C++ executables with zero .c file fail in build. For example, assume we have a Makefile like this: hostprogs-y := foo foo-cxxobjs := bar.o In this case, foo is treated as host-csingle and Kbuild tries to search non-existing foo.c source.
