Question about long jump implementation

[Neil Hickey <neil at petapath dot com>]

I'm trying to implement long jump and I'm using the call instruction
in the arm implementation as a reference.

The code looks like this:

    rtx callee, pat;

    callee = XEXP(operands[0], 0);
    if (GET_CODE (callee) == SYMBOL_REF
	? atdsp_is_long_call_p (SYMBOL_REF_DECL (callee))
	: !REG_P (callee)) {
	XEXP(operands[0], 0) = force_reg (SImode, callee);
    }
    pat = gen_call_internal (operands[0], operands[1]);	
    emit_call_insn(pat);
    DONE;

What I want to happen is for the function name to be copied to a
register and then the compiler emit the instruction to call the
function, by jumping to the address held in that register.

The compiler emits instructions that copy the function name to a
register, then it loads from the value of this register, before
jumping to the loaded value. What I want it to do is copy the function
name to the register, then jump to the address held in this register.

Does anyone know what it is I've done wrong and how I can get this to work?

Thanks

Neil
