Ok, so, that seems to be working correctly.

Ehm, I don’t think this is necessary. Just remove the `-Xbootclasspath/p:/home/bahram/graal/truffle/mxbuild/dists/truffle-api.jar` if you don’t want to use truffle. I’d assume that the rest works automatically, without having to add any graal-specific jars.

With the latest changes, everything is built into the same binary. The flags as above but excluding -XX:+UseJVMCICompiler correspond to the hosted mode.
