Hi All,

To enable profiling of qemu, I used the option "-pg". while compiling I got following error.
  CC    arm-softmmu/arch_init.o
  CC    arm-softmmu/cpus.o
  CC    arm-softmmu/monitor.o
  CC    arm-softmmu/cpu-exec.o
gcc: -pg and -fomit-frame-pointer are incompatible
make[1]: *** [cpu-exec.o] Error 1
make: *** [subdir-arm-softmmu] Error 2

So I removed the -fomit-frame-pointer, the code got compiled. but qemu doesnt run. It got hanged before loading the kernel image.

Any help is appreciated, I need to profile the qemu code for performance improvement.
