+       * testsuite/libffi.call/closure_stdcall.c,
+       testsuite/libffi.call/closure_thiscall.c: Remove fragile stack pointer
+       checks.  These files included inline assembly to save the stack
+       pointer before and after the call, and compare the values.  However,
+       compilers can and do leave the stack in different states for these two
+       pieces of inline assembly, such as by saving a temporary value on the
+       stack across the call; observed with gcc -Os, and verified as spurious
+       through careful inspection of disassembly.

        * testsuite/libffi.call/many.c: Avoid spurious failure due to excess
        floating-point precision.
        * testsuite/libffi.call/many_win32.c: Ditto.
