sparc/sparc32/sparcv9 GETTIME could be:

#define GETTIME(low,high) \
  {								\
    register unsigned int lowtick asm ("g1");			\
    asm ("rd %%tick, %%g1; srlx %%g1, 32, %1"			\
	 : "=r" (lowtick), "=r" (high));			\
    low = lowtick;						\
  }

sparc/sparc64 GETTIME:

#define GETTIME(low,high) \
  {								\
    uint64_t tickreg;						\
    asm ("rd %%tick, %0" : "=r" (tickreg));			\
    low = tickreg & 0xffffffff;					\
    high = tickreg >> 32;					\
  }

Cheers,
