+If defined, a function that outputs the assembler code for entry to a
+function.  The prologue is responsible for setting up the stack frame,
+initializing the frame pointer register, saving registers that must be
+saved, and allocating size additional bytes of storage for the
+local variables.  size is an integer.  file is a stdio
+stream to which the assembler code should be output.
+
+The label for the beginning of the function need not be output by this
+macro.  That has already been done when the macro is run.
+
+To determine which registers to save, the macro can refer to the array
+regs_ever_live: element r is nonzero if hard register
+r is used anywhere within the function.  This implies the function
+prologue should save register r, provided it is not one of the
+call-used registers.  (TARGET_ASM_FUNCTION_EPILOGUE must likewise use
+regs_ever_live.)
+
+On machines that have ``register windows'', the function entry code does
+not save on the stack the registers that are in the windows, even if
+they are supposed to be preserved by function calls; instead it takes
+appropriate steps to ``push'' the register stack, if any non-call-used
+registers are used in the function.
+
+On machines where functions may or may not have frame-pointers, the
+function entry code must vary accordingly; it must set up the frame
+pointer if one is wanted, and not otherwise.  To determine whether a
+frame pointer is in wanted, the macro can refer to the variable
+frame_pointer_needed.  The variable's value will be 1 at run
+time in a function that needs a frame pointer.  (see Elimination).
+
+The function entry code is responsible for allocating any stack space
+required for the function.  This stack space consists of the regions
+listed below.  In most cases, these regions are allocated in the
+order listed, with the last listed region closest to the top of the
+stack (the lowest address if STACK_GROWS_DOWNWARD is defined, and
+the highest address if it is not defined).  You can use a different order
+for a machine if doing so is more convenient or required for
+compatibility reasons.  Except in cases where required by standard
+or by a debugger, there is no reason why the stack layout used by GCC
+need agree with that used by other compilers for a machine.
