Instruction scheduler miscalculates bit sizes of data addresses, generating immediates which do not fit the long immediate slots leading to failure to load the program

[Heikki Kultala]

ADF has 3 instruciton templates: 1 with full-size long immediate, one without long immediate, one with 16-bit long immediate.

Data is put to address which is >65536. This address needs the longerst-immediate instruction scheduler.

Scheduler puts this to instruction template which only has the 16-bit long immediate.

This program then fails to load to the simulator.

[Heikki Kultala (hkultala)]

For instruction addresses the width of instruction addresses(size of instruction memory) is checked and used as bitwidth of jump targets etc in code.

Similar test should be added for data addresses (adddresses of global variables).

[Heikki Kultala (hkultala)]

Currently it propably assumes that address of any global variable fits any long immediate.

[Heikki Kultala (hkultala)]

Class TerminalImmediate has some method to ask required bit width of immediate value. Some other class is derived from this class for those data addresses. The derived class should have implementation of this method suwhich checks the data memory size.
