Jeremy Evans 661927a4c5 Switch to using a VM stack argument instead of 2nd operand for getconstant
Some tooling depends on the current bytecode, and adding an operand
changes the bytecode.  While tooling can be updated for new bytecode,
this support doesn't warrant such a change.

Jeremy Evans 6ac6de84ac Use Qtrue/Qfalse instead of 1/0 for 2nd operand to getconstant
Fixes error when using -Werror,-Wshorten-64-to-32.

Jeremy Evans fbcd065294 Remove support for nil::Constant
This was an intentional bug added in 1.9.

The approach taken here is to add a second operand to the
getconstant instruction for whether nil should be allowed and
treated as current scope.

Fixes [Bug #11718]

Drop default leaf definition and obsoleted comments
leaf is true by default. Other insns are not specifying it explicitly.
Also the comment describing why it was not leaf is outdated.

Add a specialized instruction for `.nil?` calls
This commit adds a specialized instruction for called to `.nil?`.  It is
about 27% faster than master in the case where the object is nil or not
nil.  In the case where an object implements `nil?`, I think it may be
slightly slower.  Here is a benchmark:

```ruby
require "benchmark/ips"

class Niller
  def nil?; true; end
end

not_nil = Object.new
xnil = nil
niller = Niller.new

Benchmark.ips do |x|
  x.report("nil?")    { xnil.nil? }
  x.report("not nil") { not_nil.nil? }
  x.report("niller")   { niller.nil? }
end
```

ko1 2b5bb8a087 add definemethod/definesmethod insn.
* 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.

k0kubun 193a06caf5 insns.def: opt_regexpmatch2 is not a leaf insn

Sadly opt_regexpmatch2 was not a leaf insn either.
http://ci.rvm.jp/results/trunk-vm-asserts@silicon-docker/1751213

CHECK_INTERRUPT_IN_MATCH_AT is just like RUBY_VM_CHECK_INTS, and it may
call arbitrary Ruby method, for example a GC finalizer from postponed
job in this case.

k0kubun 1f34da3709 insns.def: opt_regexpmatch1 is not a leaf insn
Given `str`, if `str_coderange(str)` is `ENC_CODERANGE_BROKEN`,
it calls `rb_raise`. And it calls `rb_funcallv` from `rb_exc_new3`.

http://ci.rvm.jp/results/trunk-vm-asserts@silicon-docker/1673244

Maybe we can have a function to directly call `exc_initialize` for this
purpose, but it may not be worth having such a function for keeping the
instruction leaf. We may even want to delete the insn
https://github.com/ruby/ruby/pull/1959.

I'm not sure whether compile.c could generate opt_regexpmatch2 for
invalid coderange string. Let's monitor that for a while.

shyouhei d46ab95376 insns.def: refactor to avoid CALL_METHOD macro
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

23,728 bytes on my machine.

I see no significant slowdown.

tenderlove 2f37847820 Speed up hash literals by duping
This commit replaces the `newhashfromarray` instruction with a `duphash`
instruction.  Instead of allocating a new hash from an array stored in
the Instruction Sequences, store a hash directly in the instruction
sequences and dup it on execution.

== Instruction sequence changes ==

```ruby
code = <<-eorby
  { "foo" => "bar", "baz" => "lol" }
eorby

insns = RubyVM::InstructionSequence.compile(code, __FILE__, nil, 0, frozen_string_literal: true)
puts insns.disasm
```

On Ruby 2.5:

```
== disasm: #<ISeq:<compiled>@test.rb:0 (0,0)-(0,36)>====================
0000 putobject        "foo"
0002 putobject        "bar"
0004 putobject        "baz"
0006 putobject        "lol"
0008 newhash          4
0010 leave
```

Ruby 2.6@r66174 3b6321083a2e3525da3b34d08a0b68bac094bd7f:

```
$ ./ruby test.rb
== disasm: #<ISeq:<compiled>@test.rb:0 (0,0)-(0,36)> (catch: FALSE)
0000 newhashfromarray             2, ["foo", "bar", "baz", "lol"]
0003 leave
```

Ruby 2.6 + This commit:

```
$ ./ruby test.rb
== disasm: #<ISeq:<compiled>@test.rb:0 (0,0)-(0,36)> (catch: FALSE)
0000 duphash                      {"foo"=>"bar", "baz"=>"lol"}
0002 leave
```

shyouhei 48649e4625 insns.def: avoid integer overflow
In these expressions `1` is of type `signed int` (cf: ISO/IEC
9899:1990 section 6.1.3.2). The variable (e.g. `num`) is of type
`rb_num_t`, which is in fact `unsigned long`.  These two expressions
then exercises the "usual arithmetic conversions" (cf: ISO/IEC
9899:1990 section 6.2.1.5) and both eventually become `unsigned long`.
The two unsigned expressions are then subtracted to generate another
unsigned integer expression (cf: ISO/IEC 9899:1990 section 6.3.6).
This is where integer overflows can occur.  OTOH the left hand side of
the assignments are `rb_snum_t` which is `signed long`.  The
assignments exercise the "implicit conversion" of "an unsigned integer
is converted to its corresponding signed integer" case (cf: ISO/IEC
9899:1990 section 6.2.1.2), which is "implementation-defined" (read:
not portable).

Casts are the proper way to avoid this problem.  Because all
expressions are converted to some integer types before any binary
operations are performed, the assignments now have fully defined
behaviour.  These values can never exceed LONG_MAX so the casts must
not lose any information.

ko1 312b105d0e introduce TransientHeap. [Bug #14858]
* transient_heap.c, transient_heap.h: implement TransientHeap (theap).
  theap is designed for Ruby's object system. theap is like Eden heap
  on generational GC terminology. theap allocation is very fast because
  it only needs to bump up pointer and deallocation is also fast because
  we don't do anything. However we need to evacuate (Copy GC terminology)
  if theap memory is long-lived. Evacuation logic is needed for each type.

  See [Bug #14858] for details.

* array.c: Now, theap for T_ARRAY is supported.

  ary_heap_alloc() tries to allocate memory area from theap. If this trial
  sccesses, this array has theap ptr and RARRAY_TRANSIENT_FLAG is turned on.
  We don't need to free theap ptr.

* ruby.h: RARRAY_CONST_PTR() returns malloc'ed memory area. It menas that
  if ary is allocated at theap, force evacuation to malloc'ed memory.
  It makes programs slow, but very compatible with current code because
  theap memory can be evacuated (theap memory will be recycled).

  If you want to get transient heap ptr, use RARRAY_CONST_PTR_TRANSIENT()
  instead of RARRAY_CONST_PTR(). If you can't understand when evacuation
  will occur, use RARRAY_CONST_PTR().

This commit removes "bitblt" and "trace_bitblt" insns, which reduces the
number of insns from 202 to 200 and fixes at least the latter build
failure. I hope this fixes the MinGW build failure as well. Let me
confirm the situation on AppVeyor CI.

Note that this is hard to fix because some MinGW environments (MSP-Greg's
MinGW CI on AppVeyor) don't reproduce this and some Linux environments
(including my local machine) don't reproduce it either. Make sure you
have the reproductive environment and confirm it's fixed when reverting
this commit.

k0kubun fb80f6c7ba insns.def: optimize & and | of Integer [experimental]
not optimizing Array#& and Array#| because vm_insnhelper.c can't easily
inline it (large amount of array.c code would be needed in vm_insnhelper.c)
and the method body is a little complicated compared to Integer's ones.
So I thought only Integer#& and Integer#| have a significant impact,
and eliminating unnecessary branches would contribute to JIT's performance.

vm_insnhelper.c: ditto

tool/transform_mjit_header.rb: make sure these instructions are inlined
on JIT.

compile.c: compile vm_opt_and and vm_opt_or.
id.def: define id for them to be used in compile.c and vm*.c
vm.c: track redefinition of Integer#& and Integer#|
vm_core.h: allow detecting redefinition of & and |

* Optcarrot benchmark

This is a kind of experimental thing but I'm committing this since the
performance impact is significant especially on Optcarrot with JIT.

shyouhei 9c6bd0d840 move ADD_PC around (take 2)
Now that we can say for sure if an instruction calls a method or
not internally, it is now possible to reroute the bugs that
forced us to revert the "move PC around" optimization.

First try: r62051
Reverted:  r63763

shyouhei 0f6708eb9b resurrect the string to expect modifications
String#freeze can be redefined to be destructive.  While such
redefinition is definitely weird, it should be possible.  Resurrect
the string to prepare for that sort of things.

shyouhei 02b52b2733 make opt_str_freeze leaf
Simply use DISPATCH_ORIGINAL_INSN instead of rb_funcall.  This is,
when possible, overall performant because method dispatch results are
cached inside of CALL_CACHE.  Should also be good for JIT.

shyouhei 33c8171c65 make opt_case_dispatch leaf
This instruction can be written without rb_funcall. It not only boosts
performance of case statements, but also makes room of future JIT
improvements.  Because opt_case_dispatch is about optimization this
should not be a bad thing to have.

shyouhei c2bfb4e93c add new instruction attribute called leaf
An instruction is leaf if it has no rb_funcall inside.  In order to
check this property, we introduce stack canary which is a random
number collected at runtime.  Stack top is always filled with this
number and checked for stack smashing operations, when VM_CHECK_MODE.

mame 2138f24c70 insns.def (invokesuper): remove a dummy receiever flag hack for ZSUPER
This is just a refactoring.

The receiver of "invokesuper" was a boolean to represent if it is ZSUPER
or not.  This was used in vm_search_super_method to prohibit ZSUPER call
in define_method. (It is currently prohibited because of the limitation
of the implementation.)

This change removes the hack by introducing an explicit flag,
VM_CALL_SUPER, to signal the information.  Now, the implementation of
"invokesuper" is consistent with "send" instruction.
