This isn't quite the same -- linux now has plugin support:
static void record_syscall_start(CPUState *cpu, int num,
abi_long arg1, abi_long arg2,
abi_long arg3, abi_long arg4,
abi_long arg5, abi_long arg6,
abi_long arg7, abi_long arg8)
{
qemu_plugin_vcpu_syscall(cpu, num,
arg1, arg2, arg3, arg4,
arg5, arg6, arg7, arg8);
gdb_syscall_entry(cpu, num);
}
static void record_syscall_return(CPUState *cpu, int num, abi_long ret)
{
qemu_plugin_vcpu_syscall_ret(cpu, num, ret);
gdb_syscall_return(cpu, num);
}
and they're strictly outside strace rather than interleaved.
