[llvm-dev] Linking Linux kernel with LLD

Place is:
https://github.com/torvalds/linux/blob/master/arch/x86/boot/compressed/Makefile#L51

It checks if -z noreloc-overflow is available and adds -pie and other flags in that case.

If I comment out this lines:
#LDFLAGS += $(shell $(LD) --help 2>&1 | grep -q "\-z noreloc-overflow" \
# && echo "-z noreloc-overflow -pie --no-dynamic-linker")?

Then as expected bfd linked vmlinux also becomes executable. And it is even still boots for me.

George.
