WITHOUT_CLANG and WITHOUT_CLANG_IS_CC were decoupled in r256915 by brooks: "Stop conflating WITHOUT_CLANG with WITHOUT_CLANG_IS_CC. This allows bootstrapping a copy of clang without building clang for the base system which is useful for nanobsd and similar setups. It's still probably wrong to conflate what is installed as /usr/bin/cc with the selection of a bootstrap compiler under WITH*_CLANG_IS_CC, but that's for another day." I would still say that WITHOUT_CLANG implies that you cannot have clang as cc, so maybe it would be better to error out in this case? -Dimitry [-- Attachment #2 --] -----BEGIN PGP SIGNATURE----- Version: GnuPG/MacGPG2 v2.0.22 (Darwin) iEYEARECAAYFAlKTSZcACgkQsF6jCi4glqNi3ACffg6SxeSeB2VRb19U3xRNYY6g l3kAoM2hyRg2I8WKpmdxzudYiHkIIU1e =1QIn -----END PGP SIGNATURE-----help
