Hi all,
As I am trying to run a thread in SE mode, I made up the following code:
void thread_main()
{
int* x = new x[10];
delete [] x;
my_exit(); // inlined assembly(asm volatile (".byte 0x61, 0x00,0x00,0x40))
}
main()
{
launch(&thread_main); // inlined assembly(asm volatile (".byte 0x62,
0x00,0x00,0x40))
wait(); // inlined assembly(asm volatile (".byte 0x63, 0x00,0x00,0x40))
}
To launch this thread, what I did was: allocate a stack, assign the pc, and
activate the thread context on another cpu. my_exit() will tell the simulator
that this thread is finished and the simulator will deallocate/halt its thread
context.
The extened assemblies are implemented following the M5FUNC pseudo instructions.
I use crosstool's g++ 3.4.3 to compile the code to alpha-linux. M5 is compiled
on a 64bit x86 machine.
I get the following message:
fatal: syscall stat64 (#425) unimplemented.
how ever, if I just change the thread_main to:
void thread_main()
{
int* x = new x
delete x;
my_exit();
}
The error will be gone. What can I do to allow the first case to work? is there
any patch for system call stat64?
Thanks!
