Hi,
I get an ICE compiling arpcache.i with avr-gcc-3.4.3+:
avr-gcc -c -Os arpcache.i
arpcache.c: In function `NutArpCacheQuery':
arpcache.c:481: error: unable to find a register to spill in class
`POINTER_REGS'
arpcache.c:481: error: this is the insn:
(insn 90 207 206 5 (parallel [
(set (mem:BLK (reg/v/f:HI 44 [ mac ]) [0 A8])
(mem:BLK (reg/v/f:HI 28 r28 [orig:46 entry ] [46]) [0 A8]))
(use (reg:QI 24 r24 [60]))
(use (const_int 1 [0x1]))
(clobber (scratch:HI))

(clobber (scratch:QI))
]) 16 {*movstrqi_insn} (insn_list 87 (insn_list 89 (nil)))

(expr_list:REG_UNUSED (scratch:QI)
(expr_list:REG_UNUSED (scratch:HI)
(expr_list:REG_UNUSED (scratch:HI)
(nil)))))))
arpcache.c:481: confused by earlier errors, bailing out
This works on 3.4.2!
It fails on 3.4.3, 3.4.4 20050202 (prerelease), and 4.0.0 20050203
(experimental)
