 Hello,
 
 here's another bug against a fairly old version of gcc. Gcc 3.3  
 produces:
          .file   "junk.c"
          .text
          .align  2
          .global foo
          .type   foo, %function
 foo:
          @ Interrupt Service Routine.
          @ args = 0, pretend = 0, frame = 4
          @ frame_needed = 1, uses_anonymous_args = 0
          str     ip, [sp, #-4]!
          mov     ip, sp
          sub     lr, lr, #4
          stmfd   sp!, {r3, fp, ip, lr, pc}
          sub     fp, ip, #4
          sub     sp, sp, #4
          mov     r3, #0
          str     r3, [fp, #-24]
          ldmea   fp, {r3, fp, ip, pc}^
          .size   foo, .-foo
          .ident  "GCC: (GNU) 3.3 20030508 (prerelease)"
 
 with gcc mainline:
          .file   "junk.c"
          .text
          .align  2
          .global foo
          .type   foo, %function
 foo:
          @ Interrupt Service Routine.
          @ args = 0, pretend = 0, frame = 4
          @ frame_needed = 1, uses_anonymous_args = 0
          str     ip, [sp, #-4]!
          mov     ip, sp
          stmfd   sp!, {r3, fp, ip, lr, pc}
          sub     fp, ip, #4
          sub     sp, sp, #4
          mov     r3, #0
          str     r3, [fp, #-24]
          ldmea   fp, {r3, fp, sp, lr}
          ldmfd   sp!, {ip}
          subs    pc, lr, #4
          .size   foo, .-foo
          .ident  "GCC: (GNU) 3.4 20030508 (experimental)"
 
 can you determine if this is correct? Thanks,
 
 Dara
