If I understand correctly, we could have a gtk-minimal that depends on mesa-minimal which is built without LLVM. If llvmpipe is only useful for GNOME Shell and the like, it's very likely that Emacs and many other packages don't need GTK-on-LLVM. =2D-=20 Pierre Neidhardt https://ambrevar.xyz/ --=-=-= Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQFGBAEBCAAwFiEEUPM+LlsMPZAEJKvom9z0l6S7zH8FAl9y6KkSHG1haWxAYW1i cmV2YXIueHl6AAoJEJvc9Jeku8x/s2AH/ifR9ECa0Zob9LSonS5t+JtlFSKbCVmU z+sfaDyp+d0o+N2sLeJwugLwBXFLuF5KdWCLNVccIl4wkuHqIlzH2KUTFjCqMJw1 H6fuZeooD527vc5AItQy8W7mSr7vIFKN11W9OjMy2qPwt5ojvw0nXl6CQQiuwXir iT2g7+NpXeRFm+WGKXJEcfd29JXd6suOQK8YjhuulX82kztRbAl4eFW9ORmCW7AL deIzjwSSnxQM2gW26qLJ2+40X23xdTg4Nh7vGC9X32f7mTFB3CC6u7dB37GYfI7+ 38UzYNx2RbM3Qk8q/Wx0xQeeMjcOCXm62QcjGSMeS2Z0oOqLrqMZFQU= =ht+4 -----END PGP SIGNATURE----- --=-=-=--
