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 :-) -- http://www.iki.fi/~ananaza/
