Fail to compile Linux kernel 2.6.29 with CodeSourcery G++ Lite 4.4-57

[qfwfq at sina.com]

 I compiled MIPS Linux kernel 2.6.29-4 with CodeSourcery G++ Lite 4.4-57 but got following error message when compiling "arch/mips/kernel/time.c"
 
    arch/mips/kernel/time.c: In function 'clocksource_set_clock':
    arch/mips/kernel/time.c: 82: error: impossible constraint in 'asm'
    make[1]: *** [arch/mips/kernel/time.o] Error 1
 
This problem doesn't happen if I compiled the kernel with CodeSourcery G++ Lite 4.2-177. 
 
Is that a known compatibility issue of latest toolchain?
