Hi, all?
First of all, I apologize you for this spam. I'm working with QEMU v0.12.1
with i386 Linux guest on x86-64 Linux host. I'm trying to find a point in
the source code where a system call from the guest OS is handled. If I'm not
mistaken, QEMU disassembles an instruction of INT # in a switch statement of
target-i386/translate.c and then calls helper_sysenter of
target-i386/op_helper.c. The problem is how to tell difference between a
system call of the guest OS and a system call of QEMU (I'm not sure of this,
though). Assume the following code is executed after compilation in the
guest OS:
int main() {
if (access("hello.txt", R_OK)!=0) {
