+/* 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
