No, the allmodconfig builds are currently using LLVM - there's other issues with rust+GCC, right now KASAN IIRC, and it generally seems like it'll be more reliable to use LLVM to get the coverage. Both compilers need to work anyway. --8Pab7+dFsmnpIdTp Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQEzBAABCgAdFiEEreZoqmdXGLWf4p/qJNaLcl1Uh9AFAmoqfqAACgkQJNaLcl1U h9AxcAf9E/oP1ZL3Gu06qhTqh4nYLlsl2eB2tx/jFQdSn1OKhVsmDjbjczaKsgZy LHqGmINsqxdstTNwEx+dR+afTJbZApGKGddu2tiEsfvP0bptDaymDHebd1lVt5bG g/Hr00vkEXyGOMK+M3BuIkZyiooP+5q02FZK/MbBRMN7yPTpJa6ldkeYxQXN4PWR z0ValSlPt8JYhmZ7R2sHu62S7q962NfPx41a/6B4wk3vbcboSupITED6RKbjaBUO wGUwmj+NFXHC5ZSy/JAFwI+JEM7eglgRC+L/aKUFfDLmVC4nGRuSflrf7RBGU5D4 XmLT0VzVKwbCySWEyK+zoLmP9sQK8w== =fG0k -----END PGP SIGNATURE----- --8Pab7+dFsmnpIdTp--
