Issue #6083 has been updated by Aaron Patterson. Ah, thanks! I think I can get it merged upstream. ---------------------------------------- Feature #6083: Hide a Bignum definition https://bugs.ruby-lang.org/issues/6083#change-45456 * Author: Koichi Sasada * Status: Closed * Priority: Normal * Assignee: Yukihiro Matsumoto * Category: * Target version: Next Major ---------------------------------------- Now, the struct RBignum which is a definition of Bignum in C is located in include/ruby/ruby.h. It means we can't change implementation of Bignum. For example, using GMP as Bignum representation. I propose to move the struct RBignum definition from include/ruby/ruby.h to bignum.c. I believe no one use struct RBignum directly (except core). It has possibility to break binary compatibility. ---Files-------------------------------- hide-bignum-internal.patch (4.66 KB) -- http://bugs.ruby-lang.org/
