Contemporary C compilers are good at function inlining. They fold
multiple functions into one. However they are not yet smart enough to
unfold a function into several ones. So generally speaking, it is
wiser for a C programmer to manually split C functions whenever
possible. That should make rooms for compilers to optimize at will.
Before this changeset insns.def was converted into single HUGE
function called vm_exec_core(). By moving each instruction's core
into individual functions, generated C source code is reduced from
3,428 lines to 2,847 lines. Looking at the generated assembly
however, it seems my compiler (gcc 6.2) is extraordinary smart so that
it inlines almost all functions I introduced in this changeset back
into that vm_exec_core. On my machine compiled machine binary of the
function does not shrink very much in size (28,432 bytes to 26,816
bytes, according to nm(1)).
I believe this change is zero-cost. Several benchmarks I exercised
showed no significant difference beyond error mergin. For instance
3 repeated runs of optcarrot benchmark on my machine resulted in:
before this: 28.330329285707490, 27.513378371065920, 29.40420215754537
after this: 27.107195867280414, 25.549324021385907, 30.31581919050884
in fps (greater==faster).

Looking at the source code, FIXABLE tends to be just before LOING2FIX
to check applicability of that operation. Why not try computing first
then check for overflow, which should be optimial.
I also tried the same thing for unsigned types but resulted in slower
execution. It seems RB_POSFIXABLE() is fast enough on modern CPUs.

NOTE:
(1) Fixnum's LSB is always 1.
It means you can always run `x - 1` without overflow.
(2) Of course `z = x + (y-1)` may overflow.
Now z's LSB is always 1, and the MSB of true result is also 1.
You can get true result in long as `(1<<63)|(z>>1)`,
and it equals to `(z<<63)|(z>>1)` == `ror(z)`.

Even if 3 operand LEA's latency is 3 cycle after SandyBridge,
it reduces code size and can be faster because of super scalar.
* insns.def (opt_plus): calculate and use rb_int2big.
On positive Fixnum overflow, `recv - 1 + obj` doesn't carry
because recv's msb and obj's msb are 0, and resulted msb is 1.
Therefore simply rshift and cast as signed long works fine.
On negative Fixnum overflow, it will carry because both arguments'
msb are 1, and resulted msb is also 1.
In this case it needs to restore carried sign bit after rshift.

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.

`flag' contains several categories of attributes and it makes us
confusion (at least, I had confused).
* rb_method_visibility_t (flags::visi)
* NOEX_UNDEF -> METHOD_VISI_UNDEF = 0
* NOEX_PUBLIC -> METHOD_VISI_PUBLIC = 1
* NOEX_PRIVATE -> METHOD_VISI_PRIVATE = 2
* NOEX_PROTECTED -> METHOD_VISI_PROTECTED = 3
* NOEX_SAFE(flag)) -> safe (flags::safe, 2 bits)
* NOEX_BASIC -> basic (flags::basic, 1 bit)
* NOEX_MODFUNC -> rb_scope_visibility_t in CREF
* NOEX_SUPER -> MISSING_SUPER (enum missing_reason)
* NOEX_VCALL -> MISSING_VCALL (enum missing_reason)
* NOEX_RESPONDS -> BOUND_RESPONDS (macro)
Now, NOEX_NOREDEF is not supported (I'm not sure it is needed).
Background:
I did not know what "NOEX" stands for.
I asked Matz (who made this name) and his answer was "Nothing".
"At first, it meant NO EXport (private), but the original
meaning was gone."
This is why I remove the mysterious word "NOEX" from MRI.
* vm_core.h: introduce `enum missing_reason' to represent
method_missing (NoMethodError) reason.
* eval_intern.h: introduce rb_scope_visibility_t to represent
scope visibility.
It has 3 method visibilities (public/private/protected)
and `module_function`.

Motivation and new data structure are described in [Bug #11203].
This patch also solve the following issues.
* [Bug #11200] Memory leak of method entries
* [Bug #11046] __callee__ returns incorrect method name in orphan
proc
* test/ruby/test_method.rb: add a test for [Bug #11046].
* vm_core.h: remvoe rb_control_frame_t::me. me is located at value
stack.
* vm_core.h, gc.c, vm_method.c: remove unlinked_method... codes
because method entries are simple VALUEs.
* method.h: Now, all method entries has own independent method
definititons. Strictly speaking, this change is not essential,
but for future changes.
* rb_method_entry_t::flag is move to rb_method_definition_t::flag.
* rb_method_definition_t::alias_count is now
rb_method_definition_t::alias_count_ptr, a pointer to the counter.
* vm_core.h, vm_insnhelper.c (rb_vm_frame_method_entry) added to
search the current method entry from value stack.
* vm_insnhelper.c (VM_CHECK_MODE): introduced to enable/disable
assertions.

rb_cref_t is data type of CREF. Now, the body is still NODE.
It is easy to understand what is CREF and what is pure NODE.
git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@49897 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
* vm_core.h, method.h: remove rb_iseq_t::cref_stack. CREF is stored
to rb_method_definition_t::body.iseq_body.cref.
* vm_insnhelper.c: modify SVAR usage.
When calling ISEQ type method, push CREF information onto method
frame, SVAR located place. Before this fix, SVAR is simply nil.
After this patch, CREF (or NULL == Qfalse for not iseq methods)
is stored at the method invocation.
When SVAR is requierd, then put NODE_IF onto SVAR location,
and NDOE_IF::nd_reserved points CREF itself.
* vm.c (vm_cref_new, vm_cref_dump, vm_cref_new_toplevel): added.
* vm_insnhelper.c (vm_push_frame): accept CREF.
* method.h, vm_method.c (rb_add_method_iseq): added. This function
accepts iseq and CREF.
* class.c (clone_method): use rb_add_method_iseq().
* gc.c (mark_method_entry): mark method_entry::body.iseq_body.cref.
* iseq.c: remove CREF related codes.
* insns.def (getinlinecache/setinlinecache): CREF should be cache key
because a different CREF has a different namespace.
* node.c (rb_gc_mark_node): mark NODE_IF::nd_reserved for SVAR.
* proc.c: catch up changes.
* struct.c: ditto.
* insns.def: ditto.
* vm_args.c (raise_argument_error): ditto.

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.

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.

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:

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'.

assume that ep is not LEP.

* insns.def, vm_insnhelper.h: fix IC positions.
* iseq.c: increment minor_version of ISeq because of above change.

functions based on [ruby-dev:37983]
* insns.def (putstring, duparray): use rb_{ary,str}_resurrect().
* iseq.c (iseq_data_to_ary): needs to result TS_VALUE.

added.
* vm_insnhelper.h: ditto.
* variable.c (rb_const_get_0), insns.def: Constants should not be
cached if const_missing is called. [ruby-core:21059] [Bug #967]

COVERAGE__ and introduce coverage.so instead. How to measure
coverage: (1) require "coverage.so", (2) require or load Ruby source
file, and (3) Coverage.result will return the same hash as COVERAGE__.
[ruby-dev:35324]
* thread.c (rb_enable_coverages): start coverage measurement by using
rb_add_event_hook.
* thread.c (rb_get_coverages): returns current results of coverage
measurement.
* include/ruby/intern.h: add prototype for above two functions.
* vm_core.h, vm.c: add field of coverages to rb_vm_t.
* insns.def (trace): remove special handling for COVERAGE__.
* iseq.c (prepare_iseq_build): switch COVERAGE__ to
rb_get_coverages().
* parse.y (coverage): ditto.
* thread.c (clear_coverage): ditto.
* lib/coverage.rb: use coverage.so instead of COVERAGE__.

for casual use. Usage: (1) assign {} to COVERAGE__, (2) require or
load Ruby source file, and (3) COVERAGE__["sourcefilepath"] will
return an array whose elements represent number of executions per
line of source code.
* vm_core.h: add field of coverage array to iseq.
* iseq.c (prepare_iseq_build): ditto.
* insns.def (trace): update coverage array.
* parse.y (coverage): create and initialize coverage array.
* compile.h (ADD_TRACE): add trace instruction to update covearge
array.
* thread.c (clear_coverage): delete coverage array when forking.
Otherwise, double count of coverage may occur.
* lib/coverage.rb: sample coverage measurement tool.
* error.c: distinguish explicitly between parse_in_eval and
mild_compile_error.
* load.c: ditto.
* vm_eval.c: ditto.

instead to use "postexe" insn.
* id.c, id.h: add a prepared id for above.

set a VM_FRAME_FLAG_PASSED flag to skip this frame when
searching ruby-level-cfp.
* eval.c, eval_intern.h, proc.c: fix to check cfp. if there is
no valid ruby-level-cfp, cause RuntimeError exception.
[ruby-dev:34128]
* vm_core.h, vm_evalbody.c, vm.c, vm_dump.c, vm_insnhelper.c,
insns.def: rename FRAME_MAGIC_* to VM_FRAME_MAGIC_*.
* KNOWNBUGS.rb, bootstraptest/test*.rb: move solved bugs.
git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@17084 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
* compile.c, insns.def: fix to use putcbase instruction for
class search. Qundef should not be used.
git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@16411 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
* eval.c (rb_f_raise): skip current control frame. [ruby-core:15589]
* insns.def (opt_div): raise as the ordinary method. [ruby-core:15589]
git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@15544 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
some compilers cannot deal it collectly. use DEC_SP instead.

string.
* re.c (rb_reg_new_ary): defined for toregexp. it concatenates
strings after each string is preprocessed.
* compile.c (compile_dstr_fragments): split from compile_dstr.
(compile_dstr): call compile_dstr_fragments.
(compile_dregx): defined for dynamic regexp.
(iseq_compile_each): use compile_dregx for dynamic regexp.

return "global-variable".
* test/ruby/test_defined.rb: add tests.
* bootstraptest/test_syntax.rb: fix a test.
