Fixes [Bug #15720]
|
|
|

only when its receiver and the argument are both Integers.
Since 6bedbf4625, Integer#[] has supported a range extraction.
This means that Integer#[] now accepts multiple arguments, which made
the method very slow unfortunately.
This change fixes the performance issue by adding a special handling for
its traditional use case: `num[idx]` where both `num` and `idx` are
Integers.

* internal.h (UNALIGNED_MEMBER_ACCESS, UNALIGNED_MEMBER_PTR):
moved from eval_intern.h.
* compile.c iseq.c, vm.c: use UNALIGNED_MEMBER_PTR for `entries`
in `struct iseq_catch_table`.
* vm_eval.c, vm_insnhelper.c: use UNALIGNED_MEMBER_PTR for `body`
in `rb_method_definition_t`.

When reviewing r66565, I overlooked that `GET_ISEQ()` and `GET_EP()` are
NOT `ec->cfp->iseq` and `ec->cfp->ep` but `reg_cfp->iseq` and
`reg_cfp->ep`.
`vm_push_frame` updates `ec->cfp` and in this case we want to check the
callee's cfp and so `ec->cfp` should be checked instead.

* insns.def: add definemethod and definesmethod (singleton method)
instructions. Old YARV contains these instructions, but it is moved
to methods of FrozenCore class because remove number of instructions
can improve performance for some techniques (static stack caching
and so on). However, we don't employ these technique and it is hard
to optimize/analysis definition sequence. So I decide to introduce
them (and remove definition methods). `putiseq` insn is also removed.
* vm_method.c (rb_scope_visibility_get): renamed to
`vm_scope_visibility_get()` and make it accept `ec`.
Same for `vm_scope_module_func_check()`.
These fixes are result of refactoring `vm_define_method`.
* vm_insnhelper.c (rb_vm_get_cref): renamed to `vm_get_cref`
because of consistency with other functions.

cfp->bp was (re-)introduced by Kokubun san, but VM doesn't use it
because I (ko1) want to remove it in a future. But using it make
leave instruction fast because of sp consisntency check.
So now VM uses cfp->bp.
To use cfp->bp, I checked the value and I found that it is not a
"initial value of sp" but a "initial value of ep". Fix this problem
and fix all bp references (this is why bp is renamed to bp_).

Add counters to count ccf (call cache fastpath) usage.
These counters will help which kind of method dispatch
is important to optimize.

similar idea to r67315, provide the following optimization
for method dispatch with lead and kw parameters.
(1) add a special branch to check passing kw arguments to
a method which has lead and kw parameters.
ex) def foo(x, k:1); end; foo(0, k:1)
(2) add a special branch to check passing no-kw arguments to
a method which has lead and kw parameters.
ex) def foo(x, k:1); end; foo(0)
For (1) and (2) cases, provide special dispatchers. For (2) case,
this patch only use the special dispatcher if all default
kw parameters are literal values (nil, 1, and so on. In other case,
kw->default_values does not contains Qundef) (and no required kw
parameters becaseu they don't pass any keyword parameters).
Passing keyword arguments with a hash object is not a scope of
this patch.
Without this patch, (1) and (2) cases use `setup_parameters_complex()`.
Especially, (2) seems frequent case for methods which extend a normal
usecase with keyword parameters (like: `exception: true`).
We can measure the performance with benchmark-driver:
With methods: def kw k1:1, k2:2; end
def m; end
With the following binaries:
clean-miniruby: unmodified trunk.
opt_miniruby1: use special branches for lead/kw parameters.
opt_miniruby2: use special dispatchers for lead/kw parameters.
opt_cc_miniruby: apply step (2).
Result with benchmark-driver:
m
opt_miniruby2: 75222278.0 i/s
clean-miniruby: 73177896.5 i/s - 1.03x slower

because it's not used outside vm*.c, and also having non-static function
without MJIT_STATIC is harmful for mswin JIT system.
I hope this fix mswin test failure starting from r67315.

There is a special optimization for "only lead parameters"
method dispatch using specialized dispatcher functions
`vm_call_iseq_setup_normal_0start...`.
Other cases (opt, rest, post, ...) we don't use specialized
dispatcher and call with `setup_parameters_complex` to
satisfy Ruby's complex parameter specification.
This commit introduce a specialize dispatcher for
methods which use only lead and optional parameters.
Two step improvements:
(1) prepare "lead/opt" only check pass.
It is to skip the `setup_parameters_complex` function.
(2) introduce specialized dispatcher for only "lead/opt"
parameters methods (vm_call_iseq_setup_normal_opt_start).
With these improvements, we achieved good micro-benchmark
results:
With a method: `def opt2 a, b=nil; end`
With the following binaries:
clean-miniruby: unmodified trunk.
opt_miniruby: apply step (1).
opt_cc_miniruby: apply step (2).
Result with benchmark-driver:
opt2(1)
opt_cc_miniruby: 42269409.1 i/s
opt_miniruby: 36304428.3 i/s - 1.16x slower
clean-miniruby: 25897409.5 i/s - 1.63x slower
opt2(1, 2)
opt_cc_miniruby: 45935145.7 i/s
opt_miniruby: 40513196.9 i/s - 1.13x slower
clean-miniruby: 29976057.6 i/s - 1.53x slower
This improvement may be trivial (difficult to improve practical
cases). However, this is enough small patch so I decide to
introduce it.

* vm_insnhelper.c: change `call_cfunc_*` parameters order
and specify a function type for the passed func ptr.
This fix reduce the number of asm instructions, such as:
# before this patch
0000000000000110 <call_cfunc_0>:
110: 48 89 fa mov %rdi,%rdx
113: 31 c0 xor %eax,%eax
115: 48 89 f7 mov %rsi,%rdi
118: ff e2 jmpq *%rdx
11a: 66 0f 1f 44 00 00 nopw 0x0(%rax,%rax,1)
# after this patch
0000000000000110 <call_cfunc_0>:
110: ff e1 jmpq *%rcx
However, this kind of instruction reduction doesn't affect
any performance because of great CPU architectures :p

These send and its variant instructions are the most frequently called
paths in the entire process. Reducing macro expansions to make them
dedicated function called vm_sendish() is the main goal of this
changeset. It reduces the size of vm_exec_coref from 25,552 bytes to
23,728 bytes on my machine.
I see no significant slowdown.

* iseq.c: before this patch, RubyVM::InstructionSequence.of(src) (ISeq in
short) returns different ISeq (wrapper) objects point to one ISeq internal
object. This patch changes this behavior to cache created ISeq (wrapper)
objects and return same ISeq object for an internal ISeq object.
* iseq.h (ISEQ_EXECUTABLE_P): introduced to check executable ISeq objects.
* iseq.h (ISEQ_COMPILE_DATA_ALLOC): reordr setting flag line to avoid
ISEQ_USE_COMPILE_DATA but compiled_data == NULL case.
* vm_core.h (rb_iseq_t): introduce `rb_iseq_t::wrapper` and
`rb_iseq_t::aux::exec`. Move `rb_iseq_t::local_hooks` to
`rb_iseq_t::aux::exec::local_hooks`.
* test/ruby/test_iseq.rb: add ISeq.of() tests.

* vm_trace.c (rb_tracepoint_enable_for_target): support targetting
TracePoint. [Feature #15289]
Tragetting TracePoint is only enabled on specified method, proc
and so on, example: `tp.enable(target: code)`.
`code` should be consisted of InstructionSeuqnece (iseq)
(RubyVM::InstructionSeuqnece.of(code) should not return nil)
If code is a tree of iseq, TracePoint is enabled on all of
iseqs in a tree.
Enabled tragetting TracePoints can not enabled again with
and without target.
* vm_core.h (rb_iseq_t): introduce `rb_iseq_t::local_hooks`
to store local hooks.
`rb_iseq_t::aux::trace_events` is renamed to
`global_trace_events` to contrast with `local_hooks`.
* vm_core.h (rb_hook_list_t): add `rb_hook_list_t::running`
to represent how many Threads/Fibers are used this list.
If this field is 0, nobody using this hooks and we can
delete it.
This is why we can remove code from cont.c.
* vm_core.h (rb_vm_t): because of above change, we can eliminate
`rb_vm_t::trace_running` field.
Also renamed from `rb_vm_t::event_hooks` to `global_hooks`.
* vm_core.h, vm.c (ruby_vm_event_enabled_global_flags): renamed
from `ruby_vm_event_enabled_flags.
* vm_core.h, vm.c (ruby_vm_event_local_num): added to count
enabled targetting TracePoints.
* vm_core.h, vm_trace.c (rb_exec_event_hooks): accepts
hook list.
* vm_core.h (rb_vm_global_hooks): added for convinience.
* method.h (rb_method_bmethod_t): added to maintain Proc
and `rb_hook_list_t` for bmethod (defined by define_method).
* prelude.rb (TracePoint#enable): extracet a keyword parameter
(because it is easy than writing in C).
It calls `TracePoint#__enable` internal method written in C.
* vm_insnhelper.c (vm_trace): check also iseq->local_hooks.
* vm.c (invoke_bmethod): check def->body.bmethod.hooks.
* vm.c (hook_before_rewind): check iseq->local_hooks
and def->body.bmethod.hooks before rewind by exception.

Here, recv can be INT2FIX(-1), which is 0xFFFF_FFFFul.
INT2FIX(1) is 3ul. So `recv - 1 + INT2FIX(1)` is:
recv 0xFFFF_FFFFul
recv-1 0xFFFF_FFFEul (note: unsigned)
recv-1+INT2FIX(1) 0x0000_0001ul Here is the overflow.
Given recv is a Fixnum, it can never be 0xFFFF_FFFD. 0xFFFF_FFFF is
the only value that can overflow this way, so special-casing this
value should just suffice.

* vm_core.h: remove `rb_execution_context_t::passed_bmethod_me`
and fix functions to pass the `me` directly.
`passed_bmethod_me` was used to make bmethod (methods defined by
`defined_method`). `rb_vm_invoke_bmethod` invoke `Proc` with `me`
information as method frame (`lambda` frame, actually).
If the proc call is not bmethod call, `passed_bmethod_me` should
be NULL. However, there is a bug which passes wrong `me` for
normal block call.
http://ci.rvm.jp/results/trunk-asserts@silicon-docker/1449470
This is because wrong `me` was remained in `passed_bmethod_me`
(and used incorrectly it after collected by GC).
We need to clear `passed_bmethod_me` just after bmethod call,
but clearing is not enough.
To solve this issue, I removed `passed_bmethod_me` and pass `me`
information as a function parameter of `rb_vm_invoke_bmethod`,
`invoke_block_from_c_proc` and `invoke_iseq_block_from_c` in vm.c.
* vm.c (invoke_iseq_block_from_c): the number of parameters is too
long so that I try to specify `ALWAYS_INLINE`.
* vm.c (invoke_block_from_c_proc): ditto.
* vm_insnhelper.c (vm_yield_with_cfunc): now there are no pathes
to use bmethod here.
