VM_METHOD_TYPE_REFINED to the class refined by the refinement if
the target module is a refinement. When a method entry with
VM_METHOD_TYPE_UNDEF is invoked by vm_call_method(), a method with
the same name is searched in refinements. If such a method is
found, the method is invoked. Otherwise, the original method in
the refined class (rb_method_definition_t::body.orig_def) is
invoked. This change is made to simplify the normal method lookup
and to improve the performance of normal method calls.
* vm_method.c (EXPR1, search_method, rb_method_entry),
vm_eval.c (rb_call0, rb_search_method_entry): do not use
refinements for method lookup.
* vm_insnhelper.c (vm_call_method): search methods in refinements if
ci->me is VM_METHOD_TYPE_REFINED. If the method is called by
super (i.e., ci->call == vm_call_super_method), skip the same
method entry as the current method to avoid infinite call of the
same method.
* class.c (include_modules_at): add a refined method entry for each
method defined in a module included in a refinement.
* class.c (rb_prepend_module): set an empty table to
RCLASS_M_TBL(klass) to add refined method entries, because
refinements should have priority over prepended modules.
* proc.c (mnew): use rb_method_entry_with_refinements() to get
a refined method.
* test/ruby/test_refinement.rb (test_inline_method_cache): do not skip
the test because it should pass successfully.
* test/ruby/test_refinement.rb (test_redefine_refined_method): new
test for the case a refined method is redefined.

add a new otpimization and its macro `OPT_CALL_CFUNC_WITHOUT_FRAME'.
This optimization makes all cfunc method calls `frameless', which
is fster than ordinal cfunc method call.
If `frame' is needed (for example, it calls another method with
`rb_funcall()'), then build a frame. In other words, this
optimization delays frame building.
However, to delay the frame building, we need additional overheads:
(1) Store the last call information.
(2) Check the delayed frame buidling before the frame is needed.
(3) Overhead to build a delayed frame.
rb_thread_t::passed_ci is storage of delayed cfunc call information.
(1) is lightweight because it is only 1 assignment to `passed_ci'.
To achieve (2), we modify GET_THREAD() to check `passed_ci' every
time. It causes 10% overhead on my envrionment.
This optimization only works for cfunc methods which do not need
their `frame'.
After evaluation on my environment, this optimization does not
effective every time. Because of this evaluation results, this
optimization is disabled at default.
* vm_insnhelper.c, vm.c: add VM_PROFILE* macros to measure behaviour
of VM internals. I will extend this feature.
* vm_method.c, method.h: change parameters of the `invoker' function.
Receive `func' pointer as the first parameter.
git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@37293 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
`invoker'. `invoker' function invoke cfunc body
(rb_method_cfunc_t::func).
`invoker' is set at method definition timing.
With this change, the big `switch' (branch) in `call_cfunc()'
is no longer needed.
However, the performance benefit is only a bit.
* vm_core.h (rb_call_info_t::aux::func): add a new field to store
cfunc body function pointer.
* vm_method.c (call_cfunc_invoker_func): add a new function which
returns a suitable invoke function.
* vm_method.c (setup_method_cfunc_struct): added.
* vm_method.c (rb_add_method): fix to set `invoker'.
* vm_eval.c (vm_call0_body): catch up above changes.
* vm_insnhelper.c (call_cfunc): removed.
* vm_insnhelper.c (vm_call_cfunc): fix to call cfunc body
with `invoker' function.
git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@37268 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
This condition will be true after r37258.
* vm_insnhelper.c (vm_caller_setup_args): remove `UNLIKELY' on
checking blockiseq (it seems `LIKELY').

rb_define_method_fast(). Defined method with this C API
does not make a method frame. It is bit lightweight than
ordinal C functions. Now only 0 or 1 argc are permitted.
* method.h (VM_METHOD_TYPE_CFUNC_FRAMELESS): rename macro name
from VM_METHOD_TYPE_CFUNC_FAST.
* vm_insnhelper.c, vm_method.c: rename related functions.
* proc.c (rb_method_entry_arity): catch up above changes.

about method_missing process. Use `vm_call_method()' to invoke
`method_missing' method instead of `rb_funcall2()'.
In `vm_call_method()', set fastpath to `vm_call_method_missing()'
if it can be cached.
* vm_core.h (rb_call_info_t): add new field
`rb_call_info_t::aux::missing_reasion' to pass the reason to
`vm_call_method_missing()'.
git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@37243 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
with rb_call_info_t to speedup `attr' getter and setter.
Cached index is stored in rb_call_info_t::aux::index.
`index' == 0 means not cached. `index' > 0 means cached and cached
index is `index - 1'.
* insns.def ((get|set)instancevariable): use new wrapper functions
vm_(get|set)instancevariable() defined in vm_insnhelper.c.
* vm_core.h (rb_call_info_t::aux): introduce new union data because
opt_pc can share with index.
git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@37228 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
this method call needs splat argument because cahced functions
(vm_call_attrset, vm_call_ivar, vm_call_cfunc_fast_(unary|binary))
do not check an arity.
* bootstraptest/test_method.rb: add a test to check an above issue.

This method is similar to VM_METHOD_TYPE_CFUNC methods, but
called cfunc without building new frame (does not push new control
frame). If error is occured in cfunc, the backtrace only shows
caller frame and upper.
This kind of methods can be added by rb_define_method_fast().
This feature is similar to specialized instructions (opt_plus, etc),
but more flexible (but a bit slower).
* class.c (rb_define_method_fast): added.
Maybe it will be renamed soon.
* vm_insnhelper.c (vm_call_method): support method type
VM_METHOD_TYPE_CFUNC_FAST.
* proc.c (rb_method_entry_arity): catch up new method type.
* vm_method.c (rb_add_method_cfunc_fast): added.
git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@37198 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
If `enable' is 0 then CI_SET_FASTPATH() doesn't work.
And add new configuration option OPT_CALL_FASTPATH. If this macro
was defined by 0, then CI_SET_FASTPATH() doesn't work any more.
* vm_insnhelper.c (vm_call_method): Pass `0' for `enabled' parameter
of CI_SET_FASTPATH if this method is protected.
git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@37197 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
`CI_SET_FASTPATH(ci, func)'. This macro set `ci->call' as `func'.
`func' (ci->call) is called at the last of `send'
(and `invokesuper') instruction.
`CI_SET_FASTPATH' does not set `ci->call' when the method
(stored in `ci->me') is `protected'.
* vm_insnhelper.c (vm_call_method): use `CI_SET_FASTPATH'.
After several checking (visibility, argc checking), the result of
checking can be reused until re-definition of this method
with inline method cache.
Note that this optimization is now experimental.
If you find any problem about it, please tell us.

- move all `call' related functions to the last of file.
- make functions for respective method types in vm_call_method().
(all functions have same function parameters)
* vm_core.h: add `opt_pc' filed in `rb_call_info_t'
as temporal variable.
* vm_eval.c (vm_call0_body): catch up above cahnges.
git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@37185 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
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.
* vm_core.h, compile.c, insns.def: introduce VM_CALL_ARGS_SKIP_SETUP
VM_CALL macro. This flag indicates that this call can skip
caller_setup (block arg and splat arg).
* compile.c: catch up above changes.
* iseq.c: catch up above changes (especially for TS_CALLINFO).
* tool/instruction.rb: catch up above chagnes.
* vm_insnhelper.c, vm_insnhelper.h: ditto. Macros and functions
parameters are changed.

This data structure contains information including inline method
cache. After that, `struct iseq_inline_cache_entry' does not
need to contain inline cache for method invocation.
Other information will be added to this data structure.
* vm_core.h (rb_iseq_t): add `callinfo_entries' and `callinfo_size'
members to `rb_iseq_t'.
* insns.def, compile.c: Use CALL_INFO instead of IC.
* tool/instruction.rb: support CALL_INFO as operand type.
* vm_insnhelper.c, vm_insnhelper.h: ditto.

klass to fix method lookup order, and use klass even if klass is
not a module to make refinements in class_eval invoked on classes

* eval.c (rb_using_module): accept a class as the second argument.
* eval.c (rb_mod_using, f_using): raise a TypeError if the argument
is not a module.
* test/ruby/test_refinement.rb: add new tests for the above changes.

`bp' can be calculate by `sp' (stack pointer) of previous frame.
Now, `bp_check' field is remained for debug. You can eliminate
this field by setting VM_DEBUG_BP_CHECK as 0.
* vm_insnhelper.c (vm_base_ptr): add `vm_base_ptr(cfp).
This function calculates base pointer from cfp.
* vm_insnhelper.c (vm_setup_method): push `recv' value on top of
value stack (before method parameters).
This change is for keeping consistency with normal method dispatch.
* insns.def: fix to use vm_base_ptr().
* vm.c (vm_exec): ditto.
* vm_dump.c: remove `bp' related dumps.
* cont.c (fiber_init): fix to check VM_DEBUG_BP_CHECK.
