nari 90b7073842 * parse.y: support Symbol GC. [ruby-trunk Feature #9634] ... See this ticket about Symbol GC. * include/ruby/ruby.h: Declare few functions. * rb_sym2id: almost same as old SYM2ID but support dynamic symbols. * rb_id2sym: almost same as old ID2SYM but support dynamic symbols. * rb_sym2str: almost same as `rb_id2str(SYM2ID(sym))` but not pin down a dynamic symbol. Declare a new struct. * struct RSymbol: represents a dynamic symbol as object in Ruby's heaps. Add few macros. * STATIC_SYM_P: check a static symbol. * DYNAMIC_SYM_P: check a dynamic symbol. * RSYMBOL: cast to RSymbol * gc.c: declare RSymbol. support T_SYMBOL. * internal.h: Declare few functions. * rb_gc_free_dsymbol: free up a dynamic symbol. GC call this function at a sweep phase. * rb_str_dynamic_intern: convert a string to a dynamic symbol. * rb_check_id_without_pindown: not pinning function. * rb_sym2id_without_pindown: ditto. * rb_check_id_cstr_without_pindown: ditto. * string.c (Init_String): String#intern and String#to_sym use rb_str_dynamic_intern. * template/id.h.tmpl: use LSB of ID as a flag for determining a static symbol, so we shift left other ruby_id_types. * string.c: use rb_sym2str instead `rb_id2str(SYM2ID(sym))` to avoid pinning. * load.c: use xx_without_pindown function at creating temporary ID to avoid pinning. * object.c: ditto. * sprintf.c: ditto. * struct.c: ditto. * thread.c: ditto. * variable.c: ditto. * vm_method.c: ditto. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@45426 b2dd03c8-39d4-4d8f-98ff-823fe69b080e		2014-03-26 04:57:47 +00:00
