From d6f5da84e3ec73e439ba602b32d7fcc958d6bd59 Mon Sep 17 00:00:00 2001 From: akr Date: Mon, 9 Nov 2009 11:18:17 +0000 Subject: * thread.c (rb_gc_save_machine_context): don't save the stack pointer in this function. (RB_GC_SAVE_MACHINE_CONTEXT): call rb_gc_save_machine_context and save the stack pointer at caller side. (rb_thread_schedule_rec): use RB_GC_SAVE_MACHINE_CONTEXT instead of rb_gc_save_machine_context. (blocking_region_begin): changed to a macro. use RB_GC_SAVE_MACHINE_CONTEXT instead of rb_gc_save_machine_context.
