2019-04-11	s390: make chkbss work with clang	Arnd Bergmann	1	-1/+2
	llvm skips an empty .bss section entirely, which makes the check fail with an unexpected error: /tmp/binutils-multi-test/bin/s390x-linux-gnu-objdump: section '.bss' mentioned in a -j option, but not found in any input file error: arch/s390/boot/compressed/decompressor.o .bss section is not empty ../arch/s390/scripts/Makefile.chkbss:20: recipe for target 'arch/s390/boot/compressed/decompressor.o.chkbss' failed Change the check so we first see if a .bss section exists before trying to read its size.

2019-01-28	s390: make built-in.a not directly depend on *.o.chkbss files	Masahiro Yamada	1	-14/+11
	When I was refactoring cmd_ar_builtin in scripts/Makefile.build, I noticed the build breakage of s390. Some Makefiles of s390 add extra dependencies to built-in.a; built-in.a depends on timestamp files *.o.chkbss, but $(AR) does not want to include them into built-in.a. Insert a phony target 'chkbss' in between so that $(AR) can take $(filter-out $(PHONY), $^) as input. While I was here, I refactored Makefile.chkbss a little bit.

2018-07-02	s390/build: add *.o.chkbss files to targets list	Vasily Gorbik	1	-2/+6
	Adding .o.chkbss files to targets list makes sure that the kbuild is aware of them and removes them during make clean. Also remove .o.chkbss file before an actual check, to avoid having stale *.o.chkbss file left even if the check is failed.

2018-06-25	s390: add custom target and make path extension optional for .bss check	Vasily Gorbik	1	-1/+6
	"chkbss-target" could be now used to override default target .bss check is bound to. Objects to be checked are only path extended when needed.

2018-05-09	s390: introduce compile time check for empty .bss section	Vasily Gorbik	1	-0/+14
	Introduce compile time check for files which should avoid using .bss section, because of the following reasons: - .bss section has not been zeroed yet, - initrd has not been moved to a safe location and could be overlapping with .bss section.
