I want to say this is binutils bug from the sparc target header:
SPARC has 32 integer registers and 32 floating point registers.
64 bit SPARC has 32 additional fp regs, but the odd numbered ones are not
accessible. We still account for them to simplify register computations
(eg: in CLASS_MAX_NREGS). There are also 4 fp condition code registers, so
32+32+32+4 == 100.
Register 100 is used as the integer condition code register.
Register 101 is used as the soft frame pointer register. */
