mame cd6df5fb3c Refactor the internal data format for coverage measurement
To prepare new measuring targets: branch and method coverages.
So far, iseq->coverage was an array of counts executed for line coverage.
Now, it is a three-element array for each measuring target,
whose first element is an array for line coverage.
The second element is planned for branch coverage, and the third will be
for method coverage.

ko1 7d8a415bc2 check break target correctly.
* compile.c (iseq_compile_each0): save target child_iseq in the catch-table
  for break. This iseq is not for continuation, but for search key at
  vm_throw_start().

* vm_insnhelper.c (vm_throw_start): check saved iseq first.

* iseq.h: add comment for it.

* test/ruby/test_iterator.rb (test_ljump): add a test for the issue:
    def call b; b.call; end
    call(Proc.new{break}){} #=> (1) should raise LocalJumpError
    call(Proc.new{break})   #=> (2) shoudd raies LocalJumpError, too.
  but (1) doesn't raise LocalJumpError.

  This issue is reported by Matz.

ko1 478003f6df rename absolute_path to realpath internally and introduce pathobj.
* vm_core.h: rename absolute_path to realpath because it is expected name.
  external APIs (#absolute_path methods) are remained.

* vm_core.h: remove rb_iseq_location_struct::path and
  rb_iseq_location_struct::absolute_path and introduce pathobj.
  if given path equals to given absolute_path (and most of case
  it is true), pathobj is simply given path String. If it is not same,
  pathobj is Array and pathobj[0] is path and pathobj[1] is realpath.

  This size optimization reduce 8 bytes and
  sizeof(struct rb_iseq_constant_body) is 200 bytes -> 192 bytes
  on 64bit CPU.

  To support this change, the following functions are introduced:
    * pathobj_path() (defined in vm_core.h)
    * pathobj_realpath() (ditto)
    * rb_iseq_path() (decl. in vm_core.h)
    * rb_iseq_realpath() (ditto)
    * rb_iseq_pathobj_new() (ditto)
    * rb_iseq_pathobj_set() (ditto)

* vm_core.h (rb_binding_t): use pathobj instead of path. If binding
  is given at eval methods, realpath (absolute_path) was caller's
  realpath. However, they should use binding's realpath.

ko1 3dbb390180 * introduce new ISeq binary format serializer/de-serializer
and a pre-compilation/runtime loader sample.
  [Feature #11788]

* iseq.c: add new methods:
  * RubyVM::InstructionSequence#to_binary_format(extra_data = nil)
  * RubyVM::InstructionSequence.from_binary_format(binary)
  * RubyVM::InstructionSequence.from_binary_format_extra_data(binary)

* compile.c: implement body of this new feature.

* load.c (rb_load_internal0), iseq.c (rb_iseq_load_iseq):
  call RubyVM::InstructionSequence.load_iseq(fname) with
  loading script name if this method is defined.

  We can return any ISeq object as a result value.
  Otherwise loading will be continue as usual.

  This interface is not matured and is not extensible.
  So that we don't guarantee the future compatibility of this method.
  Basically, you should'nt use this method.

* iseq.h: move ISEQ_MAJOR/MINOR_VERSION (and some definitions)
  from iseq.c.

* encoding.c (rb_data_is_encoding), internal.h: added.

* vm_core.h: add several supports for lazy load.
  * add USE_LAZY_LOAD macro to specify enable or disable of
    this feature.
  * add several fields to rb_iseq_t.
  * introduce new macro rb_iseq_check().

* insns.def: some check for lazy loading feature.

* vm_insnhelper.c: ditto.

* proc.c: ditto.

* vm.c: ditto.

* test/lib/iseq_loader_checker.rb: enabled iff suitable
  environment variables are provided.

* test/runner.rb: enable lib/iseq_loader_checker.rb.

* sample/iseq_loader.rb: add sample compiler and loader.

    $ ruby sample/iseq_loader.rb [dir]

  will compile all ruby scripts in [dir].
  With default setting, this compile creates *.rb.yarb files
  in same directory of target .rb scripts.

    $ ruby -r sample/iseq_loader.rb [app]

  will run with enable to load compiled binary data.

ko1 d5ec9ec308 * vm_core.h: split rb_call_info_t into several structs.
* rb_call_info (ci) has compiled fixed information.
  * if ci->flag & VM_CALL_KWARG, then rb_call_info is
    also rb_call_info_with_kwarg. This technique reduce one word
    for major rb_call_info data.
  * rb_calling_info has temporary data (argc, blockptr, recv).
    for each method dispatch. This data is allocated only on
    machine stack.
  * rb_call_cache is for inline method cache.
  Before this patch, only rb_call_info_t data is passed.
  After this patch, above three structs are passed.
  This patch improves:
  * data locarity (rb_call_info is now read-only data).
  * reduce memory consumption (rb_call_info_with_kwarg,
    rb_calling_info).
* compile.c: use above data.

ko1 7cf523c7db * vm_opts.h, iseq.c, iseq.h: add compile option to force frozen
string literals.
  [Feature #11473]
  This addition is not specification change, but to try frozen
  string literal world discussed on [Feature #11473].
  You can try frozen string literal world using this magical line:
    RubyVM::InstructionSequence.compile_option =
      {frozen_string_literal: true}
  Note that this is a global compilation option, so that you need to
  compile another script like that:
    p 'foo'.frozen? #=> false
    RubyVM::InstructionSequence.compile_option =
      {frozen_string_literal: true}
    p 'foo'.frozen? #=> false, because this line is already compiled.
    p eval("'foo'.frozen?") #=> true
  Details:
    * String literals are deduped by rb_fstring().
    * Dynamic string literals ("...#{xyz}...") is now only frozen,
      not deduped. Maybe you have other ideas.
  Now, please do not use this option on your productions :)
  Of course, current specification can be changed.
* compile.c: ditto.
* test/ruby/test_iseq.rb: add a test.

ko1 e4198a73d4 * make rb_iseq_t T_IMEMO object (type is imemo_iseq).
All contents of previous rb_iseq_t is in rb_iseq_t::body.
  Remove rb_iseq_t::self because rb_iseq_t is an object.
  RubyVM::InstructionSequence is wrapper object points T_IMEMO/iseq.
  So RubyVM::ISeq.of(something) method returns different wrapper
  objects but they point the same T_IMEMO/iseq object.
  This patch is big, but most of difference is replacement of
  iseq->xxx to iseq->body->xxx.
  (previous) rb_iseq_t::compile_data is also located to
  rb_iseq_t::compile_data.
  It was moved from rb_iseq_body::compile_data.
  Now rb_iseq_t has empty two pointers.
  I will split rb_iseq_body data into static data and dynamic data.
* compile.c: rename some functions/macros.
  Now, we don't need to separate iseq and iseqval (only VALUE).
* eval.c (ruby_exec_internal): `n' is rb_iseq_t (T_IMEMO/iseq).
* ext/objspace/objspace.c (count_imemo_objects): count T_IMEMO/iseq.
* gc.c: check T_IMEMO/iseq.
* internal.h: add imemo_type::imemo_iseq.
* iseq.c: define RubyVM::InstructionSequnce as T_OBJECT.
  Methods are implemented by functions named iseqw_....
* load.c (rb_load_internal0): rb_iseq_new_top() returns
  rb_iseq_t (T_IMEMO/iesq).
* method.h (rb_add_method_iseq): accept rb_iseq_t (T_IMEMO/iseq).
* vm_core.h (GetISeqPtr): removed because it is not T_DATA now.
* vm_core.h (struct rb_iseq_body): remove padding for

before:
  total heap usage: 49,622 allocs, 20,492 frees, 8,697,493 bytes allocated
after:
  total heap usage: 48,935 allocs, 19,805 frees, 8,373,773 bytes allocated

(numbers from x86-64)

v2 changes based on ko1 recommendations [ruby-core:64883]:
- squashed in-place direct thread translation to avoid alloc+copy
- renamed rb_iseq_untranslate_threaded_code to rb_iseq_original_iseq,
  cache new iseq->iseq_original field.

* compile.c (rb_iseq_translate_threaded_code): modify in-place w/o copy
  (rb_vm_addr2insn): new function for debug
  (rb_iseq_original_iseq): ditto
  (iseq_set_sequence): assign iseq_encoded directly
  [Feature #10185]

* vm_core (rb_iseq_t): move original ->iseq to bottom

* iseq.c (iseq_free, iseq_free): adjust for new layout
  (rb_iseq_disasm): use original iseq for dump
  (iseq_data_to_ary): ditto
  (rb_iseq_line_trace_each): ditto
  (rb_iseq_build_for_ruby2cext): use iseq_encoded directly

* vm_dump.c (rb_vmdebug_debug_print_pre): use original iseq

normal 36b476cd1e struct iseq_compile_data_storage: 16 bytes (from 32) overhead
This reduces the iseq_compile_data_storage header from 32 to 16
bytes on 64-bit systems.

pos and size fields cannot exceed 32-bit sizes due to stack size
limits.  Using a flexible array for the buffer also saves us 8
bytes of pointer overhead.

* iseq.h (struct iseq_catch_table_entry): shrink to 32 bytes on 64-bit

This drops a few minor page faults on my system at startup.
Using 64-bit start, end, cont, and sp fields are unnecessary as
label_get_position and label_get_sp only return int values.
label_get_position and label_get_sp should probably return
unsigned, but that is a future change.

Most iseq do not have a catch_table, so avoid needlessly adding
4-8 bytes to the struct for the common case.

Changes from v2:
- iseq_catch_table_size removed, use if (...) for (;...;)

Changes from v1:
- renamed iseq->_catch_table to iseq->catch_table
- iseq_catch_table_bytes: made a static inline function
- iseq_catch_table_size: new function replaces the
  iseq_catch_table_each iterator macro

ko1 7049d9c80d * iseq.h, iseq.c, compile.c: Change the line number data structure
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.
