Hi,
compiling linux-2.6.24 for sparc fails with:

sparc-elf-gcc -c -O2 netdev-delta.c -mno-fpu"
netdev.c-11.i: In function 'e1000e_update_stats':
netdev.c-11.i:84: error: unable to find a register to spill in class 'FP_REGS'
netdev.c-11.i:84: error: this is the insn:
(insn 166 123 140 4 netdev.c-11.i:76 (set (reg:DI 262 [
<variable>.stats.ptc1522 ])
        (mem/s:DI (plus:SI (reg/v/f:SI 26 %i2 [orig:121 adapter ] [121])
                (reg:SI 24 %i0 [244])) [15 <variable>.stats.ptc1522+0 S8 A64]))

                (reg:SI 24 %i0 [244])) [15 <variable>.stats.ptc1522+0 S8 A64])
        (nil)))
netdev.c-11.i:84: confused by earlier errors, bailing out
