[Qemu-devel] [PATCH] build: remove CONFIG_LIBDECNUMBER
Posted by Paolo Bonzini 6 years, 6 months ago 
It is used only by PPC TCG, so just move it in target/ppc/Makefile.objs

FWIW, it *should* be used by target/s390x as well.

I suppose this isn't horrible, if it needed to be replicated.

If it has to be replicated, it should be

obj-y += ../../libdecnumber/

I'll post v2.

I think I wasn't clear -- s390x does not yet use libdecnumber because we
haven't written the emulation instructions.  But we should do.  It shouldn't
even be particularly hard, since all of the heavy lifting is in the library itself.

So no need to add anything at the moment; you've simply answered my question
about what *should* happen.

Well, if it should happen later, it might as well happen now even if
it's not replicated...
