[avr-gcc-list] Legal registers

Hi All. Does it somewhere specify that avrgcc and its library routines
should only use a subset of the AVR registers (say 0,1,18-31), or can
the whole 32 be used if required? I ask because it would save a deal of
pushing and popping in a preemptive os if you knew for sure register
subset x would never be used.
