Function Documentation

genLoadArrayAddress()

t_regID genLoadArrayAddress	(	t_program *	program,
		t_symbol *	array,
		t_regID	rIdx )

Generate instructions that load the address of an array element to a register.

Parameters

program	The program where the array belongs.
array	The symbol object that refers to an array.
rIdx	Register that at runtime contains an index into the array.

Returns

The identifier of the register that (at runtime) will contain the address of the array element. If the symbol is not of the correct type, REG_0 is returned instead.
