Hi,

I am using GCC 3.4 snapshot dated 17-03-2004.Please find following testcase 
which to produce the bug. 

test.c
*************************************************************
#pragma interrupt
void isr()
{
}
void delay(int a)
{
}
int main()
{
  return 0;
}
*************************************************************
Above test code is compiled with following options to gcc,
-m2e -S -O2

Since #pragma interrupt is written above "isr", so only "isr" should be treated 
as interrupt handler. But the functions mentioned below "isr" are also treated 
as interrupt handlers i.e. it saves all registers and generates "rte" instead 
of "rts". 

Compiler should treat only "isr" as interuupt handler.

Regards,
Anil Paranjpe
