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.

Operand unification technique enable to combine
an instruction and specific operands and make new
instruction.
* defs/opt_operand.def: add several configuration
of operand unifications.
* insns.def: use `int' instead to suppress warning.

enable/disable global method caching. [ruby-dev:46203] [Bug #7111]
* vm_method.c (rb_method_entry_get_with_omod): don't use global
method cache if OPT_GLOBAL_METHOD_CACHE is 0.

prefixed include guards with RUBY.
* id.h: added include guard.
* regenc.h, regint.h, regparse.h: prefixed include guards with
ONIGURUMA.

support set_trace_func (incomplete. id and klass
don't be passed). And support Thread#set_trace_func
which hook only specified thread and Thread#add_trace_func
which add new trace func instead of replace old one.
C level API was modified. See thread.c (logic) and
yarvcore.h (data structures).
* vm.c, vm_macro.def: add hook points.
* compile.c, insns.def: fix "trace" instruction.
* iseq.c, vm_macro.h: add compile option "trace_instruction".
* test/ruby/test_settracefunc.rb: hook "c-return" of set_trace_func.
