| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove some unnecessary VALUE/struct conversions and aggressively inline functions used during fiber_switch. Either of these changes alone does not yield significant performance increase, but in combination they improve performance by ~6%. Arguably, removal of separate VALUE/rb_fiber_t* variables also makes the code more readable in a few places. * vm_core.h: declare rb_fiber_t typedef (rb_thread_t): fiber and root_fiber become rb_fiber_t * (from VALUE) * vm.c (rb_thread_mark): use rb_fiber_mark_self * cont.c (rb_fiber_t): prev becomes rb_fiber_t * (from VALUE) (cont_mark, cont_free): simplify conditions (rb_fiber_mark_self): new function (fiber_mark): use rb_fiber_mark_self (cont_save_thread, cont_restore_thread): inline (cont_restore_thread): simplify (fiber_setcontext): simplify conditions (rb_cont_call): remove dereference (fiber_t_alloc): update for rb_fiber_t->prev type change (rb_fiber_start): ditto (fiber_current): extract from rb_fiber_current (return_fiber): move, simplify type checks (rb_fiber_current): use fiber_current (fiber_store): simplify type checks (fiber_switch): ditto, simplify call to fiber_setcontext, use fiber_current (rb_fiber_transfer): update for type changes (rb_fiber_terminate): move, use fiber_switch (rb_fiber_resume): update for type changes (rb_fiber_reset_root_local_storage): ditto (rb_fiber_yield): use rb_fiber_switch instead of rb_fiber_transfer (rb_fiber_m_transfer): ditto [ruby-core:65518] [Feature #10341] git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@47964 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

| | | | | | | | | | | | | | | | | | | | Defragment code blocks depending on FIBER_USE_NATIVE in order to make the control flow (which is already non-trivial due to nonlocal jumps) in each case more comprehensible. Remove some unreachable code from fiber_switch (we've already excluded the case (th->fiber == fibval) at the start of the function). Remove call to rb_fiber_current which happened a few lines after accessing GET_THREAD()->fiber directly (so if that's ever 0 we're already screwed).
