* bignum.c (rb_big2ulong): the old logic seems to try to avoid

  calculating `-(long)(num-1)-1` if `num` is not LONG_MIN. (Note that
  `-LONG_MIN` may be larger than LONG_MAX) But C compilers can
  optimize it into single NEG instruction.
  Therefore those two conditions can be single if-body.

* bignum.c (rb_big2long): ditto.

* bignum.c (rb_big2ull): ditto.

* bignum.c (rb_big2ll): ditto.

Integer unification macro

2016-06-13T11:34:56+00:00

* include/ruby/ruby.h (RUBY_INTEGER_UNIFICATION): macro to tell if
  Integer is integrated.  [ruby-core:75718][Bug #12427]
* include/ruby/backward.h, internal.h (rb_cFixnum, rb_cBignum):
  fallback to rb_cInteger.
* bignum.c, numeric.c, ext/json/generator/generator.{c,h}: use the
  macro.

[Feature #12005] Unify Fixnum and Bignum into Integer

2016-05-17T06:53:48+00:00

* [Feature #12005] Unify Fixnum and Bignum into Integer

* include/ruby/ruby.h (rb_class_of): Return rb_cInteger for fixnums.

* insns.def (INTEGER_REDEFINED_OP_FLAG): Unified from
  FIXNUM_REDEFINED_OP_FLAG and BIGNUM_REDEFINED_OP_FLAG.

* vm_core.h: Ditto.

* vm_insnhelper.c (opt_eq_func): Use INTEGER_REDEFINED_OP_FLAG instead
  of FIXNUM_REDEFINED_OP_FLAG.

* vm.c (vm_redefinition_check_flag): Use rb_cInteger instead of
  rb_cFixnum and rb_cBignum.
  (C): Use Integer instead of Fixnum and Bignum.

* numeric.c (fix_succ): Removed.
  (Init_Numeric): Define Fixnum as Integer.

* bignum.c (bignew): Use rb_cInteger instead of Rb_cBignum.
  (rb_int_coerce): replaced from rb_big_coerce and return fixnums
  as-is.
  (Init_Bignum): Define Bignum as Integer.
  Don't define ===.

* error.c (builtin_class_name): Return "Integer" for fixnums.

* sprintf.c (ruby__sfvextra): Use rb_cInteger instead of rb_cFixnum.

* ext/-test-/testutil: New directory to test.
  Currently it provides utilities for fixnum and bignum.

* ext/json/generator/generator.c: Define mInteger_to_json.

* lib/mathn.rb (Fixnum#/): Redefinition removed.
