These count how many times * the instruction "sethi %hi(0xfc000), %g0" is executed. It's an * unusual way to encode a NOP and therefore will not trigger in * normal code. + * + * Starting with SPARC-T4 we have one control register per counter. + * And the counters are stored in individual registers.
