Hi,

with latest git, i cannot compile perf on 32 bit userspace with a 64 bit 
kernel.

~/src/linux-2.6/tools/perf$ make
PERF_VERSION = 2.6.39.rc6.224.g06d006f
     GEN common-cmds.h
     * new build flags or prefix
     CC perf.o
     CC builtin-annotate.o
     CC builtin-bench.o
     CC bench/sched-messaging.o
     CC bench/sched-pipe.o
     CC bench/mem-memcpy-x86-64-asm.o
bench/../../../arch/x86/lib/memcpy_64.S: Assembler messages:
bench/../../../arch/x86/lib/memcpy_64.S:28: Error: bad register name `%rdi'
bench/../../../arch/x86/lib/memcpy_64.S:33: Error: invalid instruction 
suffix for `movs'

ARCH=x86 make works fine

thanks,
riccardo

Hi,

I just send out a patch to fix this.

Could you have a try it?

Thanks,
