Linux cross compiler environment with gcc-3.2.1 and glibc-2.3.1 for StrongARM.

Kernel compiled by gcc-3.2.1 cannot boot. I found that the system call cannot be invoked correctly.

The target code generated by gcc-2.95.2 and gcc-3.2.1 are different.

State-Changed-When: Thu Dec  5 03:24:22 2002
State-Changed-Why:
    There is insufficient information here for us to do anything.  You don't even say what hardware your kernel is failing to boot on; but even if you did, it's unlikely we would have a similar machine.
    
    If you want this report to be progressed you are going to have to provide a lot more information.  Please provide a code fragment that is being miscompiled -- and some indication of what you think is wrong would also be very helpful.
