/***********************************************************
A PyGreenlet is a range of C stack addresses that must be
saved and restored in such a way that the full range of the
stack contains valid data when we switch to it.
Stack layout for a greenlet:
| ^^^ |
| older data |
| |
stack_stop . |_______________|
. | |
. | greenlet data |
. | in stack |
. * |_______________| . . _____________ stack_copy + stack_saved
. | | | |
. | data | |greenlet data|
. | unrelated | | saved |
. | to | | in heap |
stack_start . | this | . . |_____________| stack_copy
| greenlet |
| |
| newer data |
| vvv |
Note that a greenlet's stack data is typically partly at its correct
place in the stack, and partly saved away in the heap, but always in
the above configuration: two blocks, the more recent one in the heap
and the older one still in the stack (either block may be empty).
Greenlets are chained: each points to the previous greenlet, which is
the one that owns the data currently in the C stack above my
stack_stop. The currently running greenlet is the first element of
this chain. The main (initial) greenlet is the last one. Greenlets
whose stack is entirely in the heap can be skipped from the chain.
The chain is not related to execution order, but only to the order
in which bits of C stack happen to belong to greenlets at a particular
point in time.
The main greenlet doesn't have a stack_stop: it is responsible for the
complete rest of the C stack, and we don't know where it begins. We
use (char*) -1, the largest possible address.
States:
stack_stop == NULL && stack_start == NULL: did not start yet
stack_stop != NULL && stack_start == NULL: already finished
stack_stop != NULL && stack_start != NULL: active
The running greenlet's stack_start is undefined but not NULL.

/***********************************************************/
/* Some functions must not be inlined:
* slp_restore_state, when inlined into slp_switch might cause
it to restore stack over its own local variables
* slp_save_state, when inlined would add its own local
variables to the saved stack, wasting space
* slp_switch, cannot be inlined for obvious reasons
* g_initialstub, when inlined would receive a pointer into its
own stack frame, leading to incomplete stack save/restore
g_initialstub is a member function and declared virtual so that the
compiler always calls it through a vtable.
slp_save_state and slp_restore_state are also member functions. They
are called from trampoline functions that themselves are declared as
not eligible for inlining.
