@andreas-schwab The error looks come from incorrect instruction size. There's some patches in openjdk master about them. 
8283737: riscv: MacroAssembler::stop() should emit fixed-length instruction sequence
8285437: riscv: Fix MachNode size mismatch for MacroAssembler::verify_oops*
8287418: riscv: Fix correctness issue of MacroAssembler::movptr

I cherry-pick them and passed build in my environment. Can you test with new patches?
