! This file is part of the gdb testsuite.
!
! It was generated using "sh-elf-gcc -S gdb1291.c", using the following
! source file:
!
!	#include <stdio.h>
!	
!	main()
!	{
!	  printf("hello world\n");
!	  sub1();
!	  sub2();
!	}
!	sub1()
!	{
!	  int buf[64];
!	
!	}
!	
!	sub2()
!	{
!	  int buf[65];
!	
!	}
!
! We use a pregenerated assembly file as the test input to avoid possible
! problems with future versions of gcc generating different code.
