iseq.c: undef allocator

2016-08-22T00:02:59+00:00

* iseq.c (Init_ISeq): undefine allocator of InstructionSequence,
  to get rid of segfaults at method call on uninitialized object.

git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@55981 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

* vm_core.h: introduce VM_FRAME_RUBYFRAME_P()

2016-08-03T01:50:50+00:00

  and VM_FRAME_CFRAME_P().
  Most of case, RUBY_VM_NORMAL_ISEQ_P() is no
  longer needed.

* vm_core.h: introduce rb_obj_is_iseq().

* cont.c, vm.c: VM_FRAME_MAGIC_DUMMY with
  VM_FRAME_FLAG_CFRAME.

rb_funcallv

2016-07-29T11:57:14+00:00

* *.c: rename rb_funcall2 to rb_funcallv, except for extensions
  which are/will be/may be gems.  [Fix GH-1406]

* 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.

* iseq.c (Init_ISeq): undef ISeq.translate and ISeq.load_iseq

2016-07-13T05:26:00+00:00

  to prevent calling super classes' methods.

  Without this patch, you can write workaround like:

    class << RubyVM::InstructionSequence
      def translate; end
      undef translate
    end

* test/ruby/test_iseq.rb: add a test.

* iseq.h (struct iseq_compile_data): use struct rb_id_table

2016-05-14T18:43:11+00:00

  instead of st_table.

* iseq.c (prepare_iseq_build): don't allocate ivar_cache_table
  until it has at least one element.

* iseq.c (compile_data_free): free ivar_cache_table only if it
  is allocated.

* compile.c (get_ivar_ic_value): allocate if the table is not
  allocated yet.

* compile.c (iseq_compile_each): share InlineCache during same

2016-05-11T12:50:38+00:00

	  instance variable accesses. Reducing memory consumption,
	  rasing cache hit rate and rasing branch prediction hit rate
	  are expected. A part of [Bug #12274].

	* iseq.h (struct iseq_compile_data): introduce instance
	  variable IC table for sharing.

	* iseq.c (prepare_iseq_build, compile_data_free):
	  construct/destruct above table.

remove rb_thread_t::base_block

2016-03-28T21:40:55+00:00

* error.c (rb_compile_err_append): rb_thread_t::base_block is no
  longer used.
* iseq.c (rb_iseq_compile_with_option): ditto, no protection is
  needed.

git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@54345 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

remove rb_thread_t::parse_in_eval

2016-03-28T21:39:24+00:00

* parse.y (struct parser_params): move parse_in_eval flag from
  rb_thread_t.
* parse.y (rb_parser_set_context): set parsing context, not only
  mild error flag.
* iseq.c (rb_iseq_compile_with_option): the parser now refers no
  thread local states to be restored.
* vm_eval.c (eval_string_with_cref): ditto.

suppress warning

2016-03-21T13:53:25+00:00

* iseq.c (rb_iseq_compile_with_option): suppress
  maybe-uninitialized warning by gcc 4.8.
