/* 16-01-91 TetiSoft Changed DRV_START from D4 back to D3
 *          (CClib.library V3.0 seems to keep D3)
 *
 * 20-05-91 TetiSoft Changed ARV_START to A2 to gain another register variable
 *          Added AR_TEMP
 *          Changed out.c to use AR_TEMP instead of (ARV_START-1)
 *          Changed FD2Stubs to keep A2
 *          Changed TOP to keep A2
 *	    Changed lmath.asm to keep A2
 *
 * Register Usage of HCC is now as follows:
 * D0,D1,A0,A1 Scratch
 * D2 Temporary Register for Data Shifts (ASL etc)
 * D3,D4,D5,D6,D7 Register Variables
 * A2,A3,A4 Register Variables
 * A5 Local Stack Frame
 * A6 Temporary Reg for Structure Assignments AND Base Addr for Library Calls
 * A7 Stack Pointer
 *
 * Temporary registers are not saved between function or library calls,
 * even if CClib.library V3.0 saves D2, the routines in lmath.asm,
 * the stub codes generated by FD2Stubs and the code generated by HCC
 * destroys it.
 * Register variables are saved on function or library entry and restored 
 * at exit. If you write assembler subroutines for HCC, you MUST save these
 * registers!
 * Since CClib.library calls require parameters on stack AND library base in
 * A6, it would be very difficult to create stub codes that saves A6 without
 * changing A7. Also the execution speed gain of this function calls would be
 * lost. So I decided to give up A6 as local stack pointer and use A5 instead.
 * This resulted in the fact that only A3 and A4 were address register
 * variables. Therefore I changed the register usage for structure assignments
 * from A2 to A6 to gain another register variable.
