------- Additional Comments From rearnsha@gcc.gnu.org  2003-05-22 10:40 -------
Already fixed on trunk, now fixed for 3.3.1 with:

2003-05-19  Nick Clifton  <nickc@redhat.com>

        * config/arm/arm.c (use_return_insn): Do not use a single return
        instruction for interrupt handlers which have to create a stack
        frame.
        (arm_expand_prologue): Do not pre-bias the return address of
        interrupt handlers which create a stack frame.

In both cases the code now generated is:

        str     ip, [sp, #-4]!
        mov     ip, sp
        stmfd   sp!, {r1, r2, r3, fp, ip, lr, pc}
        sub     fp, ip, #4
        sub     sp, sp, #4
        ...  @ body of function.
        ldmea   fp, {r1, r2, r3, fp, sp, lr}
        ldmfd   sp!, {ip}
        subs    pc, lr, #4
