SPARC ICC register presents in ALL_REGS class only which can not be a pressure class. That is the reason for the problem. I also found a typo in the check code (it collected hard registers of all non-pressure classes although it should collect the pressure classes hard registers). I found more complication with the check code in MIPS target. So it took more time than I did. Currently I am testing the patch and submit it for approval soon.
