Is it acceptable? (We have similar + experience at Ruby 1.9, + for example "RARRAY(ary)->ptr" to "RARRAY_PTR(ary)". + + * internal.h: add some macros. + * RBASIC_CLEAR_CLASS(obj) clear RBasic::klass to make it internal + object. + * RBASIC_SET_CLASS(obj, cls) set RBasic::klass. + * RBASIC_SET_CLASS_RAW(obj, cls) same as RBASIC_SET_CLASS + without write barrier (planned). + * RCLASS_SET_SUPER(a, b) set super class of a. + + * array.c, class.c, compile.c, encoding.c, enum.c, error.c, eval.c, + file.c, gc.c, hash.c, io.c, iseq.c, marshal.c, object.c, + parse.y, proc.c, process.c, random.c, ruby.c, sprintf.c, + string.c, thread.c, transcode.c, vm.c, vm_eval.c, win32/file.c: + Use above macros and functions to access RBasic::klass. + + * ext/coverage/coverage.c, ext/readline/readline.c, + ext/socket/ancdata.c, ext/socket/init.c, + * ext/zlib/zlib.c: ditto. + Mon May 13 18:44:14 2013 Koichi Sasada <ko1@atdot.net> * *.c, parse.y, insns.def: use RARRAY_AREF/ASET macro |
