ruby.git/iseq.h, branch v2_1_5

* include/ruby/ruby.h (struct rb_data_type_struct), gc.c: add

2013-06-19T06:26:01+00:00

  rb_data_type_struct::flags. Now, this flags is passed
  at T_DATA object creation. You can specify FL_WB_PROTECTED
  on this flag.
* iseq.c: making non-shady iseq objects.
* class.c, compile.c, proc.c, vm.c: add WB for iseq objects.
* vm_core.h, iseq.h: constify fields to detect WB insertion.

vm_core.h: flip_cnt in rb_iseq_t

2013-01-08T05:41:44+00:00

* vm_core.h (rb_iseq_t): move flip_cnt from struct iseq_compile_data,
  because it has same life span as enclosing iseq.  [Bug #7671]

compile.c, vm_insnhelper.c: flip-flop without hidden string key

2012-12-10T06:11:16+00:00

* compile.c (iseq_compile_each): count flip-flop state in local iseq
  not in each iseqs, so that the keys can be other than hidden
  strings.  [ruby-core:47253] [Bug #6899]
* vm_insnhelper.c (lep_svar_get, lep_svar_set, vm_getspecial): store
  flip-flop states in an array instead of a hash.
* iseq.c (set_relation): main iseq also can has local scope.

* iseq.h: iseq_catch_table_entry::catch_type should be

2012-12-03T10:03:25+00:00

  Fixnum because they are pushed into Array in a compiler.
  [Bug #7502]
* test/ruby/test_objectspace.rb: add a test of this issue.



git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@38156 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

[EXPERIMENTAL]

2012-11-30T17:00:30+00:00

* iseq.c: add following two methods.
* ISeq#line_trace_all returns all line traces (line numbers)
* ISeq#line_trace_specify(pos, set) set `pos'th line event to
  specified_line event (if set is true).
  These features are introduced for debuggers (mainly to make
  breakpoint).
* iseq.h: add decl. of C APIs.
* test/ruby/test_iseq.rb: add tests.
* vm_trace.c: add `specified_line' event.
* include/ruby/ruby.h: ditto.

Feature #7035

2012-09-24T08:36:53+00:00

* compile.c (defined_expr), insns.def (defined): share single frozen
  strings.  [EXPERIMENTAL] [ruby-core:47558][Feature #7035]
* iseq.c (rb_iseq_defined_string): make expression strings.

* iseq.h, iseq.c, compile.c: Change the line number data structure

2011-08-24T06:31:15+00:00

  to solve an issue reported at [ruby-dev:44413] [Ruby 1.9 - Bug #5217].
  Before this fix, each instruction has an information including
  line number (iseq::iseq_insn_info_table).  Instead of this data
  structure, recording only line number changing places
  (iseq::iseq_line_info_table).
  The order of entries in iseq_line_info_table is ascending order of
  iseq_line_info_table_entry::position.  You can get a line number
  by an iseq and a program counter with this data structure.
  This fix reduces memory consumption of iseq (bytecode).
  On my measurement, a rails application consumes 21.8MB for
  iseq with this fix on the 32bit CPU.  Without this fix, it
  consumes 24.7MB for iseq [ruby-dev:44415].
* proc.c: ditto.
* vm_insnhelper.c: ditto.
* vm_method.c: ditto.
* vm.c (rb_vm_get_sourceline): change to use rb_iseq_line_no().

* method.h, internal.h iseq.h: declare internal functions.

2011-06-18T03:49:33+00:00

* compile.c, eval.c, iseq.c, object.c, parse.y, proc.c, process.c,
  thread.c, vm.c, vm_eval.c, vm_insnhelper.c, vm_method.c: don't
  declare internal functions.

  Note that rb_method_entry_eq() is defined in vm_method.c but
  there was a declaration in proc.c with different const-ness.
  Now it is declared in method.h with same const-ness to the
  definition.

* object.c (rb_mod_module_exec): don't declare functions declared in
  include/ruby/intern.h.
