/* A C expression to allocate run-time space for a trampoline. The expression

If this macro is not defined, by default the trampoline is allocated as a
stack slot. This default is right for most machines. The exceptions are
machines where it is impossible to execute instructions in the stack area.
On such machines, you may have to implement a separate stack, using this
macro in conjunction with output_function_prologue () and
output_function_epilogue ().
FP points to a data structure, a `struct function', which describes the
compilation status of the immediate containing function of the function
