Hi, is it possible to log some values from memory every time the instruction counter hits a certain value?
Effectively, I want to achieve what would be called a tracepoint in GDB. Since tracepoints seem not to be implemented with QEMU, I would like to do a quick hack that just logs the variables that I would like to trace. Unfortunately, I'm having problems: I tried to add a printf() into the gen_intermediate_code_internal() function in target-i386/translate.c, right before the breakpoint handling code. The code logs the correct values, but it gets called by far not as often as it should be. If I connect GDB through the network interface and set a breakpoint at the position that I'd like to trace, the breakpoint (and suddenly, also my logging code) is hit far more often. How can I get my code getting called as often as it should be? What am I doing wrong? Thanks a lot! Simon
