For interrupt routines, C28 option --isr_save_vcu_regs=on/off only saves/restores VCU registers if any save-on-call register is also save/restored.
With --isr_save_vcu_regs=on, VCU registers are save/restored if:
- the interrupt routine makes any function calls since all save-on-call registers are saved/restored
- the interrupt routine generates any save-on-call save/restores
If an interrupt routine does not make any function calls, and does not use any save-on-call registers, then option --isr_save_vcu_regs=on will not work to generate VCU register save/restores.
