We are working on a Graal configuration that can be competitive with C1 in terms of compilation times. Graal’s design is actually much closer to C1 than C2. Significant parts including backend and register allocation originate directly from a port of C1 sources from C++ to Java (e.g., https://github.com/beehive-lab/Maxine-VM/commit/75e69aeccaf9960c7e842de40e41f8b518273e7d).
