-/* This implementation can handle any ARGC value but only
-   normal integer type parameters. Parameters of type float,
-   double, complex and structure with sizes 0, 2, 4 or 8
-   won't work.
-   makecontext sets up a stack and the registers for the
-   user context. The stack looks like this:
-	   size                         offset
-    %r15 ->    +-----------------------+
-	     8 | back chain (zero)     |  0
-	     8 | reserved              |  8
-	   144 | save area for (*func) | 16
-	       +-----------------------+
-	     n | overflow parameters   | 160
-	       +-----------------------+
-   The registers are set up like this:
-     %r2-%r6: parameters 1 to 5
-     %r7    : (*func) pointer
-     %r8    : uc_link from ucontext structure
-     %r9    : address of setcontext
-     %r14   : return address to uc_link trampoline
-     %r15   : stack pointer.
-
-   The trampoline looks like this:
-     basr  %r14,%r7
-     lgr   %r2,%r8
-     br    %r9.  */
