     1.8 ++ * Reporter: marcus@mc.pp.se
     1.9 ++ * Summary:  Stackpointer messed up on SuperH
    1.10 ++ * Keywords: wrong-code
    1.11 ++ * Description:
    1.12 ++ * When a function with 5 arguments is called in both branches of a
    1.13 ++ * conditional, and only the last argument differs, the code to push that
    1.14 ++ * last argument on the stack gets confused. 
    1.15 ++ * Space for the fifth argument is reserved on the stack by the
    1.16 ++ * instruction I have marked as "A".  However, if the else-branch is
    1.17 ++ * taken the stackpointer is decremented _again_ at "B".  This
    1.18 ++ * decrementation is never restored, and it is only due to the
    1.19 ++ * restoration of r15 from r14 that the function works at all.  With
    1.20 ++ * -fomit-frame-pointer it will crash.
    1.21 ++ *
    1.22 ++ * Testcase tweaked by dank@kegel.com
    1.23 ++ * Not marked as xfail since it's a regression from hardhat 2.0 gcc-2.97 
    1.24 ++ * and dodes gcc-3.0.2
