I used to do that with qemu 0.7. I did not dig into this deep enough
to find the minimal changes but at least the following was enough:
- define DEBUG_EXEC in cpu-exec.c
- disable USE_DIRECT_JUMP in exec-all.h
- disable USE_CODE_COPY in target-i386/cpu.h
- force dc->jmp_opt to zero in target-i386/translate.c
Would be nice if enabling PC traces were possible with e.g. command
line (maybe requiring config time enable would be good too :-)
