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/Kbuild.include | 8 -------- 1 file changed, 8 deletions(-) (limited to 'scripts/Kbuild.include') diff --git a/scripts/Kbuild.include b/scripts/Kbuild.include index 7484b9d8272f..a675ce11a573 100644 --- a/scripts/Kbuild.include +++ b/scripts/Kbuild.include @@ -192,14 +192,6 @@ clean := -f $(srctree)/scripts/Makefile.clean obj # $(Q)$(MAKE) $(hdr-inst)=dir hdr-inst := -f $(srctree)/scripts/Makefile.headersinst obj -# Prefix -I with $(srctree) if it is not an absolute path. -# skip if -I has no parameter -addtree = $(if $(patsubst -I%,%,$(1)), \ -$(if $(filter-out -I/% -I./% -I../%,$(1)),$(patsubst -I%,-I$(srctree)/%,$(1)),$(1)),$(1)) - -# Find all -I options and call addtree -flags = $(foreach o,$($(1)),$(if $(filter -I%,$(o)),$(call addtree,$(o)),$(o))) - # echo command. # Short version is used, if $(quiet) equals `quiet_', otherwise full one. echo-cmd = $(if $($(quiet)cmd_$(1)),\ -- cgit
