We should avoid using the space character when passing arguments to clang, because static code analysis check tool such as sparse may misinterpret the arguments followed by spaces as build targets hence cause the build to fail.

2017-10-07kbuild: revert $(realpath ...) to $(shell cd ... && /bin/pwd)Masahiro Yamada1-2/+2
I thought commit 8e9b46679923 ("kbuild: use $(abspath ...) instead of $(shell cd ... && /bin/pwd)") was a safe conversion, but it changed the behavior. $(abspath ...) / $(realpath ...) does not expand shell special characters, such as '~'. Here is a simple Makefile example: ---------------->8---------------- $(info /bin/pwd: $(shell cd ~/; /bin/pwd)) $(info abspath: $(abspath ~/)) $(info realpath: $(realpath ~/)) all: @: ---------------->8---------------- $ make /bin/pwd: /home/masahiro abspath: /home/masahiro/workspace/~ realpath: This can be a real problem if 'make O=~/foo' is invoked from another Makefile or primitive shell like dash. This commit partially reverts 8e9b46679923.

Commit 5620a0d1aac ("firmware: delete in-kernel firmware") removed the entire firmware directory. Unfortunately it thereby also removed the support for built-in firmware. This restores the ability to build firmware directly into the kernel by pruning the original Makefile to the necessary minimum.

git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core Pull firmware removal from Greg KH: "Many many years ago (at the kernel summit in Boston), we all came to the agreement that the firmware/ tree should be dropped from the kernel, and everyone use the linux-firmware package instead. For some minor reason, David Woodhouse didn't send the pull request at that point in time, and everyone forgot about this. The topic came up in the hallway track at the Plumbers conference this week, so here's a single patch that drops the whole firmware tree. The last firmware update was back in 2013, and all distros have been using linux-firmware instead since at least that year, if not before. The only commits to that directory since 2013 was some kbuild fixups for various build tool issues. So lets finally drop this, we don't need to lug them around in the kernel source tree anymore, especially as no one wants or uses them. This has passed build testing with 0-day, I don't think it made it into linux-next this week, but I figured it was good to get in before 4.14-rc1 was out" * tag 'firmware_removal-4.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: firmware: delete in-kernel firmware

2017-09-01kbuild: use $(abspath ...) instead of $(shell cd ... && /bin/pwd)Masahiro Yamada1-6/+6
Kbuild conventionally uses $(shell cd ... && /bin/pwd) idiom to get the absolute path of the directory because GNU Make 3.80, the minimal supported version at that time, did not support $(abspath ...) or $(realpath ...). Commit 37d69ee30808 ("docs: bump minimal GNU Make version to 3.81") dropped the GNU Make 3.80 support, so we are now allowed to use those make-builtin helpers. This conversion will provide better portability without relying on the pwd command or its location /bin/pwd. I am intentionally using $(realpath ...) instead $(abspath ...) in some places. The difference between the two is $(realpath ...) returns an empty string if the given path does not exist. It is convenient in places where we need to error-out if the makefile fails to create an output directory.

2017-08-21Kbuild: use -fshort-wchar globallyArnd Bergmann1-1/+1
Commit 971a69db7dc0 ("Xen: don't warn about 2-byte wchar_t in efi") added the --no-wchar-size-warning to the Makefile to avoid this harmless warning: arm-linux-gnueabi-ld: warning: drivers/xen/efi.o uses 2-byte wchar_t yet the output is to use 4-byte wchar_t; use of wchar_t values across objects may fail Changing kbuild to use thin archives instead of recursive linking unfortunately brings the same warning back during the final link. The kernel does not use wchar_t string literals at this point, and xen does not use wchar_t at all (only efi_char16_t), so the flag has no effect, but as pointed out by Jan Beulich, adding a wchar_t string literal would be bad here. Since wchar_t is always defined as u16, independent of the toolchain default, always passing -fshort-wchar is correct and lets us remove the Xen specific hack along with fixing the warning.

2017-07-12disable new gcc-7.1.1 warnings for nowLinus Torvalds1-0/+3
I made the mistake of upgrading my desktop to the new Fedora 26 that comes with gcc-7.1.1. There's nothing wrong per se that I've noticed, but I now have 1500 lines of warnings, mostly from the new format-truncation warning triggering all over the tree. We use 'snprintf()' and friends in a lot of places, and often know that the numbers are fairly small (ie a controller index or similar), but gcc doesn't know that, and sees an 'int', and thinks that it could be some huge number. And then complains when our buffers are not able to fit the name for the ten millionth controller. These warnings aren't necessarily bad per se, and we probably want to look through them subsystem by subsystem, but at least during the merge window they just mean that I can't even see if somebody is introducing any *real* problems when I pull. So warnings disabled for now. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2017-06-30kbuild: handle libs-y archives separately from built-in.o archivesNicholas Piggin1-4/+4
The thin archives build currently puts all lib.a and built-in.o files together and links them with --whole-archive. This works because thin archives can recursively refer to thin archives. However some architectures include libgcc.a, which may not be a thin archive, or it may not be constructed with the "P" option, in which case its contents do not get linked correctly. So don't pull .a libs into the root built-in.o archive. These libs should already have symbol tables and indexes built, so they can be direct linker inputs. Move them out of the --whole-archive option, which restore the conditional linking behaviour of lib.a to thin archives builds.

2017-06-25kbuild: Add __cc-option macroMatthias Kaehlcke1-1/+1
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.
