+
+ * compile.c (iseq_compile_each), vm_insnhelper.c (vm_invoke_block,
+ vm_throw): allow "return" and "yield" even in singleton class
+ definition. based on a patch from wanabe <s.wanabe AT gmail.com>
+ for "return". [ruby-core:21379] [ruby-dev:40975]
+
+ * insns.def (defineclass): ditto (straightforwardly push block ptr,
+ instead of dfp ptr with special flag).
+
+ * vm_core.h (RUBY_VM_CLASS_SPECIAL_P): ditto (no longer needed).
+
+ * proc.c (proc_new): ditto (remove handling for special flag).
+
+ * bootstraptest/test_jump.rb: add tests for above.
+
Mon May 10 02:29:51 2010 Yusuke Endoh <[email protected]>
* cont.c (fiber_switch): raise FiberError when returning to dead
