Hi Antti, Thanks for the reply. Honestly, I am new to QEMU, hence I just tried following the steps you had mentioned to extract PCs without actually knowing what each of those mean.
As you had said, - I defined DEBUG_EXEC in cpu-exec.c - I disabled USE_DIRECT_JUMP in exec-all.h - I disabled USE_CODE_COPY in target-i386/cpu.h - I hardcoded force_dc->jmp_opt to equal zero in target-i386/translate.c (force_dc->jmp_opt = 0;) However, when I try to make the qemu-0.9.0 that I have, I get the following error - ########################################################## $ make .... /qemu-0.9.0-trial/target-i386/translate.c /qemu-0.9.0-trial/target-i386/translate.c: In function `gen_goto _tb': /qemu-0.9.0-trial/target-i386/translate.c:1766: error: too many arguments to function `gen_op_goto_tb0' /qemu-0.9.0-trial/target-i386/translate.c:1768: error: too many arguments to function `gen_op_goto_tb1' make[1]: *** [translate.o] Error 1 make[1]: Leaving directory `/qemu-0.9.0-trial/i386-linux-user' make: *** [subdir-i386-linux-user] Error 2 ###################################################### Do you know if I'm doing something wrong here? Also, since qemu-0.7 doesn't seem to be available for download from the qemu webpage, I couldn't try the same with qemu-0.7. I appreciate your help on this. Thanks, -Shashi.

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/
