is defined. If the return value is also an object of
RubyVM::InstructionSequence, then use it instead of created one.
For example, this method is useful to test iseq dumper/loader
such as RubyVM::InstructionSequence#to_a and rb_iseq_load().
Because this method is for such internal experimental usage,
the interface is not matured. For example, this interface has
no extensibility. Two or more translaters can not run
simultaneously.
So that we don't guarantee future compatibility of this method.
Basically, do not use this method.

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.

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

https://bugs.ruby-lang.org/issues/10440#change-49694
* change terminology `arg' to `param'.
* move rb_iseq_t::arg_* to rb_iseq_t::param.
* move rb_iseq_t::arg_size to rb_iseq_t::param::size.
* move rb_iseq_t::argc to rb_iseq_t::param::lead_num.
* move rb_iseq_t::arg_opts to rb_iseq_t::param::opt_num.
* move rb_iseq_t::arg_rest to rb_iseq_t::param::rest_start.
* move rb_iseq_t::arg_post_num to rb_iseq_t::param::post_num.
* move rb_iseq_t::arg_post_start to rb_iseq_t::param::post_start.
* move rb_iseq_t::arg_block to rb_iseq_t::param::block_start.
* move rb_iseq_t::arg_keyword* to rb_iseq_t::param::keyword.
rb_iseq_t::param::keyword is allocated only when keyword
parameters are available.
* introduce rb_iseq_t::param::flags to represent parameter
availability. For example, rb_iseq_t::param:🎏:has_kw
represents that this iseq has keyword parameters and
rb_iseq_t::param::keyword is allocated.
We don't need to compare with -1 to check availability.
* remove rb_iseq_t::arg_simple.
* compile.c: catch up this change.
* iseq.c: ditto.
* proc.c: ditto.
* vm.c, vm_args.c, vm_dump.c, vm_insnhelper.c: ditto.
* iseq.c (iseq_data_to_ary): support keyword argument.

keyword arguments/parameters and a splat argument.
[Feature #10440] (Details are described in this ticket)
Most of complex part is moved to vm_args.c.
Now, ISeq#to_a does not catch up new instruction format.
* vm_core.h: change iseq data structures.
* introduce rb_call_info_kw_arg_t to represent keyword arguments.
* add rb_call_info_t::kw_arg.
* rename rb_iseq_t::arg_post_len to rb_iseq_t::arg_post_num.
* rename rb_iseq_t::arg_keywords to arg_keyword_num.
* rename rb_iseq_t::arg_keyword to rb_iseq_t::arg_keyword_bits.
to represent keyword bitmap parameter index.
This bitmap parameter shows that which keyword parameters are given
or not given (0 for given).
It is refered by `checkkeyword' instruction described bellow.
* rename rb_iseq_t::arg_keyword_check to rb_iseq_t::arg_keyword_rest
to represent keyword rest parameter index.
* add rb_iseq_t::arg_keyword_default_values to represent default
keyword values.
* rename VM_CALL_ARGS_SKIP_SETUP to VM_CALL_ARGS_SIMPLE
to represent
(ci->flag & (SPLAT|BLOCKARG)) &&
ci->blockiseq == NULL &&
ci->kw_arg == NULL.
* vm_insnhelper.c, vm_args.c: rewrite with refactoring.
* rewrite splat argument code.
* rewrite keyword arguments/parameters code.
* merge method and block parameter fitting code into one code base.
* vm.c, vm_eval.c: catch up these changes.
* compile.c (new_callinfo): callinfo requires kw_arg parameter.
* compile.c (compile_array_): check the last argument Hash object or
not. If Hash object and all keys are Symbol literals, they are
compiled to keyword arguments.
* insns.def (checkkeyword): add new instruction.
This instruction check the availability of corresponding keyword.
For example, a method "def foo k1: 'v1'; end" is cimpiled to the
following instructions.
0000 checkkeyword 2, 0 # check k1 is given.
0003 branchif 9 # if given, jump to address #9
0005 putstring "v1"
0007 setlocal_OP__WC__0 3 # k1 = 'v1'
0009 trace 8
0011 putnil
0012 trace 16
0014 leave
* insns.def (opt_send_simple): removed and add new instruction
"opt_send_without_block".
* parse.y (new_args_tail_gen): reorder variables.
Before this patch, a method "def foo(k1: 1, kr1:, k2: 2, **krest, &b)"
has parameter variables "k1, kr1, k2, &b, internal_id, krest",
but this patch reorders to "kr1, k1, k2, internal_id, krest, &b".
(locate a block variable at last)
* parse.y (vtable_pop): added.
This function remove latest `n' variables from vtable.
* iseq.c: catch up iseq data changes.
* proc.c: ditto.
* class.c (keyword_error): export as rb_keyword_error().
* common.mk: depend vm_args.c for vm.o.
* hash.c (rb_hash_has_key): export.
* internal.h: ditto.

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_size and line_info_size may be 32-bit.
4GB instruction sequences should be big enough for anyone.
Other existing line info counters are 32-bit, and nobody

RBASIC_CLASS(obj) macro which returns a class of `obj'.
This change is a part of RGENGC branch [ruby-trunk - Feature #8339].
* object.c: add new function rb_obj_reveal().
This function reveal interal (hidden) object by rb_obj_hide().
Note that do not change class before and after hiding.
Only permitted example is:
klass = RBASIC_CLASS(obj);
rb_obj_hide(obj);
....
rb_obj_reveal(obj, klass);
TODO: API design. rb_obj_reveal() should be replaced with others.
TODO: modify constified variables using cast may be harmful for
compiler's analysis and optimizaton.
Any idea to prohibt inserting RBasic::klass directly?
If rename RBasic::klass and force to use RBASIC_CLASS(obj),
then all codes such as `RBASIC(obj)->klass' will be
compilation error. Is it acceptable? (We have similar
experience at Ruby 1.9,
for example "RARRAY(ary)->ptr" to "RARRAY_PTR(ary)".
* internal.h: add some macros.

use only a `ci' (rb_call_info_t) parameter instead of using
parameters such as `op_id', 'op_argc', `blockiseq' and flag.
These information are stored in rb_call_info_t at the compile
time.
This technique simplifies parameter passings at related
function calls (~10% speedups for simple mehtod invocation at
my machine).
`rb_call_info_t' also has new function pointer variable `call'.
This `call' variable enables to customize method (block)
invocation process for each place. However, it always call
`vm_call_general()' at this changes.
`rb_call_info_t' also has temporary variables for method
(block) invocation.

hooks (old macro name is COLLECT_USAGE_ANALYSIS).
This feature is only for VM developers. (I'm not sure I can use
`VM developers' (the plural form) in this sentence).
If VM_COLLECT_USAGE_DETAILS is not 0, VM enables the following
usage collection features:
(1) insntruction: collect intruction usages.
(2) operand: collect operand usages.
(3) register: collect register usages.
The results are stored in
RubyVM::USAGE_ANALYSIS_INSN for (1, 2),
RubyVM::USAGE_ANALYSIS_INSN_BIGRAM for (1) and
RubyVM::USAGE_ANALYSIS_REGS for (3).
You can stop collecting usages with
RubyVM::USAGE_ANALYSIS_INSN_STOP(),
RubyVM::USAGE_ANALYSIS_OPERAND_STOP(),
RubyVM::USAGE_ANALYSIS_REGISTER_STOP()
for (1), (2), (3) respectively.
You can also change the hook functions by setting
C level global variables
`ruby_vm_collect_usage_func_(insn|operand|register)'
for (1), (2), (3) respectively.

th->base_block is information for (a) parsing, (b) compiling
and (c) setting up the frame to execute the program passed by
`eval' method. For example, (1) parser need to know up-level
variables to detect it is variable or method without paren.
Befor (a), (b) and (c), VM set th->base_block by passed bindng
(or previous frame information). After execute (a), (b) and (c),
VM should clear th->base_block. However, if (a), (b) or (c)
raises an exception, then th->base_block is not cleared.
Problem is that the uncleared value th->balo_block is used for
irrelevant iseq compilation. It causes SEGV or critical error.
I tried to solve this problem: to clear them before exception,
but finally I found out that it is difficult to do it (Ruby
program can be run in many places).
Because of this background, I set th->base_block before
compiling iseq and restore it after compiling.
Basically, th->base_block is dirty hack (similar to global
variable) and this patch is also dirty.
* bootstraptest/test_eval.rb: add a test for above.

information.
rb_location_t#filename, filepath, name and line_no was moved from
rb_iseq_t. rb_location_t#basename is a new field which is
similar to `name' field without any decoration.
`name' field contains some decoration such as `block in foo'.
`basename' only contains `foo'.
rb_iseq_t contains memory object of rb_location_t.
* iseq.c: setup rb_location_t for each rb_iseq_t memory objects.
* compile.c, proc.c, vm.c, vm_dump.c, vm_eval.c, vm_insnhelper.c,
vm_method.c: support about it.

Patch by Google Inc. [ruby-core:45073].
* configure.in (RUBY_NACL): New M4 func to configure variables for
NaCl.
(RUBY_NACL_CHECK_PEPPER_TYPES): New M4 func to check the old names
of Pepper interface types.
(BTESTRUBY): New variable to specify which ruby should be run on
"make btest". NaCl can run the built binary by sel_ldr, but it need
rbconfig.rb. So this variable is distinguished from $MINIRUBY.
* thread_pthread.c: Disabled some features on NaCl.
* io.c: ditto.
* process.c: ditto.
* signal.c: ditto.
* file.c: ditto.
* missing/flock.c: ditto.

application.
* nacl/nacl-config.rb: Detects variants of NaCl SDK.
* nacl/GNUmakefile.in: Makefile template for NaCl specific build
process.
* nacl/package.rb: script for packaging a NaCl-Ruby embedding
application.
* nacl/reate_nmf.rb: Wrapper script of create_nmf.py
* dln.c (dln_load): Added a hack to call on NaCl.
* util.c (ruby_getcwd): Path to the current directort is not available
on NaCl.

number 0 means no line number info is needed. [ruby-dev:45130]
[Bug #5894]

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().

* 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.

instead, use Object as bottom, and push top_wrapper on Object.

path field into rb_iseq_t. The field contains a string representing
a path to corresponding source file. or nil when the iseq is created
from -e, stdin, eval, etc. This field is used for require_relative.
[ruby-dev:40004]
* load.c (rb_f_require_relative): add C implementation of
require_relative.
* prelude.rb (require_relative): get rid of Ruby implementation of
require_relative.

(OFFSET to IC). This IC must be same as corresponding
getinlinecache instruction's IC operand.
This change is for a little performance improvement
(getting IC directly) and is for the AOT compilation development.
* compile.c, iseq.c, insns.def: Change the approach to handling inline
cahce (IC) type operand to enable the above change.
This change also affects ISeq#to_a method. The inline cache operand
will be dumped by fixnum, the index of inline cache, in other words,
inline cache identity.
* template/insns_info.inc.tmpl, tool/instruction.rb: No need to count
inline cache size (insn_iclen()).
