[Qemu-devel] [PATCH] tests/tcg/s390x: Fix alignment of csst parameter list

[Richard Henderson]

The parameter list given in general register 1 shall be aligned
on a quadword boundary.  This test currently succeeds or fails
depending on the compiler version used and the accidential layout
of the function's stack frame.
