I think these references are not correct. The bug is due to a new version of clang, so no Fixes: tag is needed. You should put "clang 4" in the title. > Signed-off-by: Emmanuel Roullit <emmanuel.roul...@gmail.com> > --- > > v2: > * Only apply compiler flag on clang >= 4.0 Please use --in-reply-to for grouping v2 patches with v1. > --- a/mk/toolchain/clang/rte.toolchain-compat.mk > +++ b/mk/toolchain/clang/rte.toolchain-compat.mk > +ifeq ($(shell test $(CLANG_MAJOR_VERSION)$(CLANG_MINOR_VERSION) -ge 40 && > echo 1), 1) > + CC_PACKED_MEMBER_WERROR := true > +endif > --- a/mk/toolchain/clang/rte.vars.mk > +++ b/mk/toolchain/clang/rte.vars.mk > +ifeq ($(CC_PACKED_MEMBER_WERROR),true) > +WERROR_FLAGS += -Wno-address-of-packed-member > +endif So you are completely disabling the warning? Can we assume this warning is of no interest?
