powerpc-eabi-gcc does not recognize "XER" register anymore?

[Michael Schwingen <rincewind at discworld dot dascon dot de>]

Hello,

since installing gcc-2.95.3, gcc can not handle the "XER" register anymore
when I specify it as spilled in an inline asm construct:

#define C_CALL_VOLATILE_REG
"0","3","4","5","6","7","8","9","10","11","12","cr0","cr1","cr5","cr6","cr7","ctr","xer"

#define OS_SYSCALL1(a,trap) asm volatile \
           ("mr 3,%0; li 10,%1; sc"::"r"(a),"n"(trap)\
           : C_CALL_VOLATILE_REG )

../include/foo.h:119:unknown register name `xer' in `asm'

gcc-2.95.2 and the snapshots 20000417 and 20000619 work fine - why was this
changed? How do I tell the compiler now that XER may change during the asm?

cu
Michael
