asmjit getgpArg(), getxmmArg() and make() replacement

Question

I'm currently working on a legacy codebase which used old asmjit with the intenion of migrating to using the latest asmjit. I've been able to figure out signature replacements e.g. call, setArg I need help in understanding alternatives for old asmjit functions like getGpArg, getXmmArg and make().

    //old signatures
    X86CompilerFuncCall ctx = c.call(address);
    ctx->setPrototype(kX86FuncConvCompatFastCall, FuncBuilder1<int, int>());
    ctx->setArgument(0, var);
    ctx->setReturn(var);

    //New signature
    auto ctx_new = c.call((uint64_t)address, FunctionSignature1<int, int>());
    ctx_new->SetArg(0, var);
    ctx_new->setRet(0, var);

Any suggestions from asmjit users/readers for alternatives to getGpArg, getXmmArg and make() is welcome.
