Hi,
in arch/sparc/boot/Makefile, there is a rule below.
$(obj)/btfix.S: $(obj)/btfixupprep vmlinux FORCE
$(call if_changed,btfix)
This makes btfix.S file using btfixupprep executable.
and from the definition below,
quiet_cmd_btfix = BTFIX $@
cmd_btfix = $(OBJDUMP) -x vmlinux | $(obj)/btfixupprep > $@
I can see to make the btfix.S, the make runs
objdump -x vmlinux | btfixupprep > btfix.S
What does btfixupprep do? maybe relocations? or function name substitution(for
sub architecture)?
Regards,
Chan
