Any reason not to just turn this into

cflags-y += $(call cc-option,$(tune-mcpu))

?


Yes, you'll need to pull up the source; the diff doesn't provide
enough context. tune-mcpu is used in the body of the else branch
hinted at by the diff. PTAL


Ah, fair enough. The warning is a little unconventional but oh well :)

If $(tune-mcpu) is empty or invalid, nothing will be added to cflags-y.

[PATCH 4/7] arc: replace cc-option-yn uses with cc-option

2021-08-16 Thread Nick Desaulniers
cc-option-yn can be replaced with cc-option. ie.
Checking for support:
ifeq ($(call cc-option-yn,$(FLAG)),y)
becomes:
ifneq ($(call cc-option,$(FLAG)),)

Checking for lack of support:
ifeq ($(call cc-option-yn,$(FLAG)),n)
becomes:
ifeq ($(call cc-option,$(FLAG)),)

This allows us to pursue removing cc-option-yn.
