     287 [C Variable] void (*C_pre_gc_hook)(int mode)
     288
     289If not {{NULL}}, the function pointed to by this variable will be
     290called before each garbage collection with a flag indicating what kind
     291of collection was performed (either {{0}} for a minor collection or
     292{{2}} for a resizing collection). A "resizing" collection means a
     293secondary collection that moves all live data into a enlarged (or
     294shrinked) heap-space. Minor collections happen very frequently, so the
     295hook function should not consume too much time. The hook function may
     296not invoke Scheme callbacks.
     297
     298Note that resizing collections may be nested in normal major collections.

    287  [C Variable] void (*C_post_gc_hook)(int mode)
    288 
    289 If not {{NULL}}, the function pointed to by this variable will be called
    290 after each garbage collection with a flag indicating what kind of collection
    291 was performed (either {{0}} for a minor collection or {{1}} for a major
    292 collection). Minor collections happen very frequently, so the hook function
    293 should not consume too much time. The hook function may not invoke Scheme
    294 callbacks.

     302 [C Variable] void (*C_post_gc_hook)(int mode, long ms)
     303
     304If not {{NULL}}, the function pointed to by this variable will be
     305called after each garbage collection with a flag indicating what kind
     306of collection was performed (either {{0}} for a minor collection,
     307{{1}} for a major collection or {{2}} for a resizing
     308collection). Minor collections happen very frequently, so the hook
     309function should not consume too much time. The hook function may not
     310invoke Scheme callbacks. The {{ms}} argument records the number of
     311milliseconds required for the garbage collection, if the collection
     312was a major one. For minor collections the value of the {{ms}} argument
     313is undefined.

     79 [C function] void C_callback_adjust_stack (C_word *ptr, int size)
    8080
    8181The runtime-system uses the stack as a special allocation area and
    82 internally holds pointers to estimated limits to distinguish between Scheme
    83 data objects inside the stack from objects outside of it.
    84 If you invoke callbacks at wildly differing stack-levels,
    85 these limits may shift from invocation to invocation. Callbacks defined
    86 with {{define-external}} will perform appropriate adjustments automatically,
    87 but if you invoke {{C_callback}} manually, you should perform a
    88 {{C_callback_adjust_stack_limits}} to make sure the internal limits are
    89 set properly. {{ptr}} should point to some data object on the stack. The
    90 call will make sure the limits are adjusted so that the value pointed to
    91 by {{ptr}} is located in the stack.

    39 ; -compress-literals THRESHOLD : Compiles quoted literals that exceed the size {{THRESHOLD}} as strings and parse the strings at run-time. This reduces the size of the code and speeds up compile-times of the host C compiler, but has a small run-time performance penalty. The size of a literal is computed by counting recursively the objects in the literal, so a vector counts as 1 plus the count of the elements, a pair counts as the counts of the car and the cdr, respectively. All other objects count 1.
