From cdd750bfb1f76fe9be8cfb53cbe77b2e811081ab Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Mon, 13 May 2019 15:22:17 +0900 Subject: kbuild: remove 'addtree' and 'flags' magic for header search paths The 'addtree' and 'flags' in scripts/Kbuild.include are so compilecated and ugly. As I mentioned in [1], Kbuild should stop automatic prefixing of header search path options. I fixed up (almost) all Makefiles in the kernel. Now 'addtree' and 'flags' have been removed. Kbuild still caters to add $(srctree)/$(src) and $(objtree)/$(obj) to the header search path for O= building, but never touches extra compiler options from ccflags-y etc. [1]: https://patchwork.kernel.org/patch/9632347/ Signed-off-by: Masahiro Yamada --- scripts/Makefile.host | 12 +++++------- 1 file changed, 5 insertions(+), 7 deletions(-) (limited to 'scripts/Makefile.host') diff --git a/scripts/Makefile.host b/scripts/Makefile.host index 73b804197fca..b6a54bdf0965 100644 --- a/scripts/Makefile.host +++ b/scripts/Makefile.host @@ -67,18 +67,16 @@ _hostc_flags = $(KBUILD_HOSTCFLAGS) $(HOST_EXTRACFLAGS) \ _hostcxx_flags = $(KBUILD_HOSTCXXFLAGS) $(HOST_EXTRACXXFLAGS) \ $(HOSTCXXFLAGS_$(basetarget).o) -__hostc_flags = $(_hostc_flags) -__hostcxx_flags = $(_hostcxx_flags) - +# $(objtree)/$(obj) for including generated headers from checkin source files ifeq ($(KBUILD_EXTMOD),) ifneq ($(srctree),.) -__hostc_flags = -I$(obj) $(call flags,_hostc_flags) -__hostcxx_flags = -I$(obj) $(call flags,_hostcxx_flags) +_hostc_flags += -I $(objtree)/$(obj) +_hostcxx_flags += -I $(objtree)/$(obj) endif endif -hostc_flags = -Wp,-MD,$(depfile) $(__hostc_flags) -hostcxx_flags = -Wp,-MD,$(depfile) $(__hostcxx_flags) +hostc_flags = -Wp,-MD,$(depfile) $(_hostc_flags) +hostcxx_flags = -Wp,-MD,$(depfile) $(_hostcxx_flags) ##### # Compile programs on the host -- cgit
