* vm_core.h: revisit the structure of frame, block and env.

  [Bug #12628]

  This patch introduce many changes.

  * Introduce concept of "Block Handler (BH)" to represent
    passed blocks.

  * move rb_control_frame_t::flag to ep[0] (as a special local
    variable). This flags represents not only frame type, but also
    env flags such as escaped.

  * rename `rb_block_t` to `struct rb_block`.

  * Make Proc, Binding and RubyVM::Env objects wb-protected.

  Check [Bug #12628] for more details.

* vm_insnhelper.c: introduce rb_vm_pop_frame() and use it

2016-07-26T10:28:21+00:00

  instead of setting rb_thread_t::cfp directly.

* vm_insnhelper.c (vm_pop_frame): return the result of
  finish frame or not.

* insns.def (opt_plus): use `- 1` instead of `& (~1)` to allow

2016-06-27T18:30:12+00:00

  compilers to use x86 LEA instruction (3 operand).
  Even if 3 operand LEA's latency is 3 cycle after SandyBridge,
  it reduces code size and can be faster because of super scalar.

* insns.def (opt_plus): calculate and use rb_int2big.
  On positive Fixnum overflow, `recv - 1 + obj` doesn't carry
  because recv's msb and obj's msb are 0, and resulted msb is 1.
  Therefore simply rshift and cast as signed long works fine.
  On negative Fixnum overflow, it will carry because both arguments'
  msb are 1, and resulted msb is also 1.
  In this case it needs to restore carried sign bit after rshift.

[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.

* insns.def (defineclass): Also raise an error when redeclaring the

2016-05-10T12:46:43+00:00

  superclass of a class as Object and it has another superclass.
  [Bug #12367] [ruby-core:75446]
* test/ruby/test_class.rb: test for above.

* configure.in: check function attirbute const and pure,

2016-05-08T17:44:51+00:00

  and define CONSTFUNC and PUREFUNC if available.
  Note that I don't add those options as default because
  it still shows many false-positive (it seems not to consider
  longjmp).

* vm_eval.c (stack_check): get rb_thread_t* as an argument
  to avoid duplicate call of GET_THREAD().

  fragments.
