spill.c - another reduced test

Here is yet another different and simplified test case.

With that test case I can produce spill fails for 4.5.2, 4.6.2 and 4.7 trunk (build from around 2012-02-17).

>> avr-gcc spill.c -Os -S

spill.c: In function 'menu_cycle':
spill.c:31:1: error: unable to find a register to spill in class 'POINTER_REGS'
spill.c:31:1: error: this is the insn:
