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).

rb_control_frame_t::klass.
[Bug #11278], [Bug #11279]
rb_method_entry_t data belong to modules/classes.
rb_method_entry_t::owner points defined module or class.
module M
def foo; end
end
In this case, owner is M.
rb_callable_method_entry_t data belong to only classes.
For modules, MRI creates corresponding T_ICLASS internally.
rb_callable_method_entry_t can also belong to T_ICLASS.
rb_callable_method_entry_t::defined_class points T_CLASS or
T_ICLASS.
rb_method_entry_t data for classes (not for modules) are also
rb_callable_method_entry_t data because it is completely same data.
In this case, rb_method_entry_t::owner == rb_method_entry_t::defined_class.
For example, there are classes C and D, and incldues M,
class C; include M; end
class D; include M; end
then, two T_ICLASS objects for C's super class and D's super class
will be created.
When C.new.foo is called, then M#foo is searcheed and
rb_callable_method_t data is used by VM to invoke M#foo.
rb_method_entry_t data is only one for M#foo.
However, rb_callable_method_entry_t data are two (and can be more).
It is proportional to the number of including (and prepending)
classes (the number of T_ICLASS which point to the module).
Now, created rb_callable_method_entry_t are collected when
the original module M was modified. We can think it is a cache.
We need to select what kind of method entry data is needed.
To operate definition, then you need to use rb_method_entry_t.
You can access them by the following functions.
* rb_method_entry(VALUE klass, ID id);
* rb_method_entry_with_refinements(VALUE klass, ID id);
* rb_method_entry_without_refinements(VALUE klass, ID id);
* rb_resolve_refined_method(VALUE refinements, const rb_method_entry_t *me);
To invoke methods, then you need to use rb_callable_method_entry_t
which you can get by the following APIs corresponding to the
above listed functions.
* rb_callable_method_entry(VALUE klass, ID id);
* rb_callable_method_entry_with_refinements(VALUE klass, ID id);
* rb_callable_method_entry_without_refinements(VALUE klass, ID id);
* rb_resolve_refined_method_callable(VALUE refinements, const rb_callable_method_entry_t *me);
VM pushes rb_callable_method_entry_t, so that rb_vm_frame_method_entry()
returns rb_callable_method_entry_t.
You can check a super class of current method by
rb_callable_method_entry_t::defined_class.
* method.h: renamed from rb_method_entry_t::klass to
rb_method_entry_t::owner.
* internal.h: add rb_classext_struct::callable_m_tbl to cache
rb_callable_method_entry_t data.
We need to consider abotu this field again because it is only
active for T_ICLASS.
* class.c (method_entry_i): ditto.
* class.c (rb_define_attr): rb_method_entry() does not takes
defiend_class_ptr.
* gc.c (mark_method_entry): mark RCLASS_CALLABLE_M_TBL() for T_ICLASS.
* cont.c (fiber_init): rb_control_frame_t::klass is removed.
* proc.c: fix `struct METHOD' data structure because
rb_callable_method_t has all information.
* vm_core.h: remove several fields.
* rb_control_frame_t::klass.
* rb_block_t::klass.

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

Before this commit:
`finish frame' was place holder which indicates that VM loop
needs to return function.
If a C method calls a Ruby methods (a method written by Ruby),
then VM loop will be (re-)invoked. When the Ruby method returns,
then also VM loop should be escaped. `finish frame' has only
one instruction `finish', which returns VM loop function.
VM loop function executes `finish' instruction, then VM loop
function returns itself.
With such mechanism, `leave' instruction (which returns one
frame from current scope) doesn't need to check that this `leave'
should also return from VM loop function.
Strictly, one branch can be removed from `leave' instructon.
Consideration:
However, pushing the `finish frame' needs costs because
it needs several memory accesses. The number of pushing
`finish frame' is greater than I had assumed. Of course,
pushing `finish frame' consumes additional control frame.
Moreover, recent processors has good branch prediction,
with which we can ignore such trivial checking.
After this commit:
Finally, I decide to remove `finish frame' and `finish'
instruction. Some parts of VM depend on `finish frame',
so the new frame flag VM_FRAME_FLAG_FINISH is introduced.
If this frame should escape from VM function loop, then
the result of VM_FRAME_TYPE_FINISH_P(cfp) is true.
`leave' instruction checks this flag every time.
I measured performance on it. However on my environments,
it improves some benchmarks and slows some benchmarks down.
Maybe it is because of C compiler optimization parameters.
I'll re-visit here if this cause problems.
* insns.def (leave, finish): remove finish instruction.
* vm.c, vm_eval.c, vm_exec.c, vm_backtrace.c, vm_dump.c:
apply above changes.

dfp (dynamic frame pointer) to ep (environment pointer).
This change make VM `normal' (similar to other interpreters).
Before this commit:
Each frame has two env pointers lfp and dfp. lfp points
local environment which is method/class/toplevel frame.
lfp[0] is block pointer.
dfp is block local frame. dfp[0] points previous (parent)
environment pointer.
lfp == dfp when frame is method/class/toplevel.
You can get lfp from dfp by traversing previous environment
pointers.
After this commit:
Each frame has only `ep' to point respective enviornoment.
If there is parent environment, then ep[0] points parent
envioenment (as dfp). If there are no more environment,
then ep[0] points block pointer (as lfp). We call such ep
as `LEP' (local EP). We add some macros to get LEP and to
detect LEP or not.
In short, we replace dfp and lfp with ep and LEP.
rb_block_t and rb_binding_t member `lfp' and `dfp' are removed
and member `ep' is added.
rename rb_thread_t's member `local_lfp' and `local_svar' to
`root_lep' and `root_svar'.
(VM_EP_PREV_EP(ep)): get previous environment pointer. This macro
assume that ep is not LEP.
(VM_EP_BLOCK_PTR(ep)): get block pointer. This macro assume
that ep is LEP.
(VM_EP_LEP_P(ep)): detect ep is LEP or not.
(VM_ENVVAL_BLOCK_PTR(ptr)): make block pointer.
(VM_ENVVAL_BLOCK_PTR_P(v)): detect v is block pointer.
(VM_ENVVAL_PREV_EP_PTR(ptr)): make prev environment pointer.
(VM_ENVVAL_PREV_EP_PTR_P(v)): detect v is prev env pointer.
* vm.c: apply above changes.
(VM_EP_LEP(ep)): get LEP.
(VM_CF_LEP(cfp)): get LEP of cfp->ep.
(VM_CF_PREV_EP(cfp)): utility function VM_EP_PREV_EP(cfp->ep).
(VM_CF_BLOCK_PTR(cfp)): utility function VM_EP_BLOCK_PTR(cfp->ep).
* vm.c, vm_eval.c, vm_insnhelper.c, vm_insnhelper.h, insns.def:
apply above changes.
* cont.c: ditto.
* eval.c, eval_intern.h: ditto.
* proc.c: ditto.
* thread.c: ditto.
* vm_dump.c: ditto.
* vm_exec.h: fix function name (on vm debug mode).

(1) rename rb_location_t to rb_iseq_location_t.
(2) rename field names of rb_iseq_location_t to adjust
RubyVM::Backtrace::Location methods.
(2-1) filename -> path
(2-2) filepath -> absolute_path
(2-3) basename -> base_label
(2-4) name -> label
(3) rename filed name rb_iseq_location_t#line_no to
rb_iseq_location_t#first_lineno to clear purpose of this field.
(4) The field names rb_binding_t#(filename|line_no) are also renamed
to rb_binding_t#(path|first_lineno).
* compile.c: apply above changes.
* iseq.c: ditto.

is no longer included from vm.c). I hope this separation reduce
compile time of vm.c.
* internal.h: ditto.
* vm.c, vm_core.h, vm_dump.c, vm_eval.c: ditto.
* vm_eval.c: some functions (callee, etc) moved to vm_backtrace.c.

(1) unify similar functions (rb_backtrace_each() and
backtrace_object()). backtrace_each() is a unified function.
variation:
a) backtrace_object(): create backtrace object.
b) vm_backtrace_str_ary(): create bt as an array of string.
c) vm_backtrace_print(): print backtrace to specified file.
d) rb_backtrace_print_as_bugreport(): print backtrace on
bugreport style.
(2) remove rb_backtrace_each(). Use backtrace_each() instead.
(3) chang the type of lev parameter to size_t.
a) lev == 0 means current frame (exception, etc use it).
b) lev == 1 means upper frame (caller(0) use it).
* vm_core.h, vm_dump.c, vm_eval.c: ditto.
* vm.c (backtrace_object(), vm_backtrace_str_ary()): fix to return a
correct size of caller(lev) array.
Let n be a "caller(0).size" then ln as caller(lev).size should be
(n - lev). However, the previous implementation returns a wrong
size array (ln > n - lev). [ruby-dev:45673]
* test/ruby/test_backtrace.rb: add tests for backtrace.

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.

* vm_dump.c (rb_vm_bugreport): show "Other runtime information"
header only when available.
* vm_dump.c (rb_vm_bugreport): get rid of modifying the content of
VM directly.
* vm_dump.c (rb_vm_bugreport): check if vm is non-null.
