++/* PR optimization/11736
++ * Reporter: marcus@mc.pp.se
++ * Summary: Stackpointer messed up on SuperH
++ * Keywords: wrong-code
++ * Description:
++ * When a function with 5 arguments is called in both branches of a
++ * conditional, and only the last argument differs, the code to push that
++ * last argument on the stack gets confused.
++ * Space for the fifth argument is reserved on the stack by the
++ * instruction I have marked as "A". However, if the else-branch is
++ * taken the stackpointer is decremented _again_ at "B". This
++ * decrementation is never restored, and it is only due to the
++ * restoration of r15 from r14 that the function works at all. With
++ * -fomit-frame-pointer it will crash.
++ *
++ * Testcase tweaked by dank@kegel.com
++ * Not marked as xfail since it's a regression from hardhat 2.0 gcc-2.97
++ * and dodes gcc-3.0.2
