[Qemu-devel] compile failure if I enable guest_mem_before trace event

[Peter Maydell]

Hi; I thought I'd have a look at the guest_mem_before trace event,
but if I enable it (by deleting "disable" from the line in trace-events)
QEMU doesn't compile:

  CC      arm-softmmu/tcg/tcg-op.o
In file included from
/home/petmay01/linaro/qemu-from-laptop/qemu/include/trace-tcg.h:4:0,

../trace/generated-tcg-tracers.h: In function ‘trace_guest_mem_before_tcg’:
../trace/generated-tcg-tracers.h:11:5: error: implicit declaration of

     ^
../trace/generated-tcg-tracers.h:11:5: error: nested extern
declaration of ‘trace_guest_mem_before_trans’ [-Werror=nested-externs]

Am I doing something wrong, or is this a bug?

thanks
