Hi All,
I noticed in my builds with foo.S file I would get a warning from the
compiler the foo_s.o.tmp linker file will not be used as the code is not
linked. A strange error and the foo_s.o file would not be created. In the
mk/internal/rte.compile-pre.mk we have the following
# command to assemble a .S file to generate an object
ifeq ($(USE_HOST),1)
S_TO_O = $(CPP) $(HOST_CPPFLAGS) $($(@)_CPPFLAGS) $(HOST_EXTRA_CPPFLAGS)
$< $(@).tmp && \
$(HOSTAS) $(HOST_ASFLAGS) $($(@)_ASFLAGS) $(HOST_EXTRA_ASFLAGS) -o $@
$(@).tmp
S_TO_O_STR = $(subst ','\'',$(S_TO_O)) #'# fix syntax highlight
S_TO_O_DISP = $(if $(V),"$(S_TO_O_STR)"," HOSTAS $(@)")
else
S_TO_O = $(CPP) $(CPPFLAGS) $($(@)_CPPFLAGS) $(EXTRA_CPPFLAGS) $< -o
$(@).tmp && \
$(AS) $(ASFLAGS) $($(@)_ASFLAGS) $(EXTRA_ASFLAGS) -o $@ $(@).tmp
S_TO_O_STR = $(subst ','\'',$(S_TO_O)) #'# fix syntax highlight
S_TO_O_DISP = $(if $(V),"$(S_TO_O_STR)"," AS $(@)")
endif
I had to change the above ?.tmp? strings to ?.s? to remove this warning
and get the foo_s.o file created. Using the .s the file name becomes
foo_s.o.s
Did not try this with clang or any other compiler, but I expect we can
safely change the ?.tmp? to ?.s? IMO
Anyone else notice this problem?
