Hi Masahiro Yamada,
do you have an idea how to fix this properly - as for example LLD
hasn't this option?
Speaking of the shell-line.
I mean use the method "call ld-option".
The below should be if $linker supports z noreloc-overflow then set
-pie together with --no-dynamic-linker.
AFAICS this is for x86-64-only?
Is it possible to simplify and have have one single line...?
KBUILD_LDFLAGS += $(call ld-option, -pie) $(call ld-option, --no-dynamic-linker)
[ arch/x86/boot/compressed/Makefile ]
KBUILD_LDFLAGS := -m elf_$(UTS_MACHINE)
# Compressed kernel should be built as PIE since it may be loaded at any
# address by the bootloader.
ifeq ($(CONFIG_X86_32),y)
KBUILD_LDFLAGS += $(call ld-option, -pie) $(call ld-option, --no-dynamic-linker)
else
# To build 64-bit compressed kernel as PIE, we disable relocation
# overflow check to avoid relocation overflow error with a new linker
# command-line option, -z noreloc-overflow.
KBUILD_LDFLAGS += $(shell $(LD) --help 2>&1 | grep -q "\-z noreloc-overflow" \
&& echo "-z noreloc-overflow -pie --no-dynamic-linker")
endif
LDFLAGS_vmlinux := -T
If you need more infos let me know.
Thanks.
