- * the following macros are spliced into the OS/compiler
- * specific code, in order to simplify maintenance.

-// We can save about 10% of the time it takes to switch greenlets if
-// we thread the thread state through the slp_save_state() and the
-// following slp_restore_state() calls from
-// slp_switch()->g_switchstack() (which already needs to access it).
-//
-// However:
-//
-// that requires changing the prototypes and implementations of the
-// switching functions. If we just change the prototype of
-// slp_switch() to accept the argument and update the macros, without
-// changing the implementation of slp_switch(), we get crashes on
-// 64-bit Linux and 32-bit x86 (for reasons that aren't 100% clear);
-// on the other hand, 64-bit macOS seems to be fine. Also, 64-bit
-// windows is an issue because slp_switch is written fully in assembly
-// and currently ignores its argument so some code would have to be
-// adjusted there to pass the argument on to the
-// ``slp_save_state_asm()`` function (but interestingly, because of
-// the calling convention, the extra argument is just ignored and
-// things function fine, albeit slower, if we just modify
-// ``slp_save_state_asm`()` to fetch the pointer to pass to the
-// macro.)
-//
-// Our compromise is to use a *glabal*, untracked, weak, pointer
-// to the necessary thread state during the process of switching only.
-// This is safe because we're protected by the GIL, and if we're
-// running this code, the thread isn't exiting. This also nets us a
-// 10-12% speed improvement.
