-If stack checking cannot be done on your system by probing the stack with
-a load or store instruction (@pxref{Stack Checking}), define this pattern
-to perform the needed check and signaling an error if the stack
-has overflowed. The single operand is the location in the stack furthest
-from the current stack pointer that you need to validate. Normally,
-on machines where this pattern is needed, you would obtain the stack
-limit from a global or thread-specific variable or register.
