Hi.
I'm trying to run quemu-cvs on WinXP SP1 host and MinGW with gcc v3.4.2,
but qemu after start just opens console window and hangs.
After some testing I came to conclusion that this is the offending piece
of code (cpu_exec.c):
#if defined(USE_CODE_COPY)
(...)
#endif
spin_unlock(&tb_lock);
}
tc_ptr = tb->tc_ptr;
env->current_tb = tb;
/* execute the generated code */
gen_func = (void *)tc_ptr;
printf("xxx: cpu-exec.c::cpu_exec() AFTER gen_func = (void
*)tc_ptr\n");
#if defined(__sparc__)
(...)
#eise
printf("xxx: cpu-exec.c::cpu_exec() BEFORE gen_func()\n");
gen_func();
printf("xxx: cpu-exec.c::cpu_exec() AFTER gen_func()\n");
#endif
The result after executing is like:
xxx: cpu-exec.c::cpu_exec() AFTER spin_unlock(&tb_lock)
xxx: cpu-exec.c::cpu_exec() AFTER gen_func = (void *)tc_ptr
xxx: cpu-exec.c::cpu_exec() BEFORE gen_func()
and then qemu hangs. Debugging this in VisualC gives me:
"Unhandled exception in qemu.exe: 0xC0000005: Access Violation"
Another strange thing is that sometimes after compile qemu makes the whole
first loop:
xxx: vl.c::main_loop() AFTER for(;;)
xxx: vl.c::main_loop() BEFORE ret=cpu_exec()
(...)
xxx: cpu-exec.c::cpu_exec() AFTER spin_unlock(&tb_lock)
xxx: cpu-exec.c::cpu_exec() AFTER gen_func = (void *)tc_ptr
xxx: cpu-exec.c::cpu_exec() BEFORE gen_func()
xxx: cpu-exec.c::cpu_exec() AFTER gen_func()
(...)
xxx: vl.c::main_loop() AFTER ret=cpu_exec()
xxx: vl.c::main_loop() BEFORE main_loop_wait(timeout)
xxx: vl.c::main_loop() AFTER main_loop_wait(timeout)
xxx: vl.c::main_loop() AFTER for(;;)
xxx: vl.c::main_loop() BEFORE ret=cpu_exec()
(...)
xxx: cpu-exec.c::cpu_exec() AFTER spin_unlock(&tb_lock)
xxx: cpu-exec.c::cpu_exec() AFTER gen_func = (void *)tc_ptr
xxx: cpu-exec.c::cpu_exec() BEFORE gen_func()
->hangs
Anyone have an idea what is wrong here?
