which has been developed by Takashi Kokubun <takashikkbn@gmail> as
YARV-MJIT. Many of its bugs are fixed by wanabe <s.wanabe@gmail.com>.
This JIT compiler is designed to be a safe migration path to introduce
JIT compiler to MRI. So this commit does not include any bytecode
changes or dynamic instruction modifications, which are done in original
MJIT.
This commit even strips off some aggressive optimizations from
YARV-MJIT, and thus it's slower than YARV-MJIT too. But it's still
fairly faster than Ruby 2.5 in some benchmarks (attached below).
Note that this JIT compiler passes `make test`, `make test-all`, `make
test-spec` without JIT, and even with JIT. Not only it's perfectly safe
with JIT disabled because it does not replace VM instructions unlike
MJIT, but also with JIT enabled it stably runs Ruby applications
including Rails applications.
I'm expecting this version as just "initial" JIT compiler. I have many
optimization ideas which are skipped for initial merging, and you may
easily replace this JIT compiler with a faster one by just replacing
mjit_compile.c. `mjit_compile` interface is designed for the purpose.
common.mk: update dependencies for mjit_compile.c.
internal.h: declare `rb_vm_insn_addr2insn` for MJIT.
vm.c: exclude some definitions if `-DMJIT_HEADER` is provided to
compiler. This avoids to include some functions which take a long time
to compile, e.g. vm_exec_core. Some of the purpose is achieved in
transform_mjit_header.rb (see `IGNORED_FUNCTIONS`) but others are
manually resolved for now. Load mjit_helper.h for MJIT header.
mjit_helper.h: New. This is a file used only by JIT-ed code. I'll
refactor `mjit_call_cfunc` later.
vm_eval.c: add some #ifdef switches to skip compiling some functions
like Init_vm_eval.
win32/mkexports.rb: export thread/ec functions, which are used by MJIT.
include/ruby/defines.h: add MJIT_FUNC_EXPORTED macro alis to clarify
that a function is exported only for MJIT.
array.c: export a function used by MJIT.
bignum.c: ditto.
class.c: ditto.
compile.c: ditto.
error.c: ditto.
gc.c: ditto.
hash.c: ditto.
iseq.c: ditto.
numeric.c: ditto.
object.c: ditto.
proc.c: ditto.
re.c: ditto.
st.c: ditto.
string.c: ditto.
thread.c: ditto.
variable.c: ditto.
vm_backtrace.c: ditto.
vm_insnhelper.c: ditto.
vm_method.c: ditto.
I would like to improve maintainability of function exports, but I
believe this way is acceptable as initial merging if we clarify the
new exports are for MJIT (so that we can use them as TODO list to fix)
and add unit tests to detect unresolved symbols.
I'll add unit tests of JIT compilations in succeeding commits.

* Known issues
* Code generated by gcc is faster than clang. The benchmark may be worse
in macOS. Following benchmark result is provided by gcc w/ Linux.
* Performance is decreased when Google Chrome is running
* JIT can work on MinGW, but it doesn't improve performance at least
in short running benchmark.
* Currently it doesn't perform well with Rails. We'll try to fix this
before release.

It seems HUGE_VAL is already used. Why not eliminate INTINITY.
NAN is also float. That of double is called nan(). This is also
fixed.

[Feature #13884]
Reduce number of memory allocations for "and", "or" and "diff"
operations on small arrays
Very often, arrays are used to filter parameters and to select
interesting items from 2 collections and very often these
collections are small enough, for example:
```ruby
SAFE_COLUMNS = [:id, :title, :created_at]
def columns
@all_columns & SAFE_COLUMNS
end
```
In this patch, I got rid of unnecessary memory allocations for
small arrays when "and", "or" and "diff" operations are performed.

To convert the object implicitly, it has had two parts in convert_type() which are
1. lookink up the method's id
2. calling the method
Seems that strncmp() and strcmp() in convert_type() are slightly heavy to look up
the method's id for type conversion.
This patch will add and use internal APIs (rb_convert_type_with_id, rb_check_convert_type_with_id)
to call the method without looking up the method's id when convert the object.

* array.c (rb_ary_concat_multi): concatenate the array without generating
temporary Array object if only one argument is given.
This is very similar with r58886.
Array#concat will be faster around 19%.
[Fix GH-1634]
### Before
Array#concat 2.187M (± 3.5%) i/s - 10.926M in 5.002829s
### After
Array#concat 2.598M (± 1.8%) i/s - 13.008M in 5.008201s
### Test code
require 'benchmark/ips'
Benchmark.ips do |x|
x.report "Array#concat" do |i|
other = [4]
i.times { [1, 2, 3].concat(other) }
end
end

* object.c (rb_equal): add optimized path to compare the objects using
rb_equal_opt(). Previously, if not same objects were given, rb_equal() would
call `==' method via rb_funcall() which took a long time.
rb_equal_opt() has provided faster comparing for Fixnum/Float/String objects.
Now, Time#eql? uses rb_equal() to compare with argument object and it will
be faster around 40% on 64-bit environment.
* array.c (rb_ary_index): remove redundant rb_equal_opt() calling.
Now, rb_equal() was optimized using rb_equal_opt().
If rb_equal_opt() returns Qundef, it will invoke rb_equal() -> rb_equal_opt(),
and it will cause the performance regression.
So, this patch will remove first redundant rb_equal_opt() calling.
* array.c (rb_ary_rindex): ditto.
* array.c (rb_ary_includes): ditto.

* array.c (ary_ensure_room_for_push): use rb_ary_modify_check() instead of
rb_ary_modify() to check whether the object can be modified for non shared
Array object. rb_ary_modify() has the codes for shared Array object too.
In here, it has condition branch for shared / non shared Array object and
it can use rb_ary_modify_check() which is smaller function than
rb_ary_modify() for non shared object.
rb_ary_modify_check() will be expand as inline function.
If it will compile with GCC, Array#<< will be faster around 8%.

The current documentation for Array#join does not mention the
special treatment of nested arrays.
It says:
> Returns a string created by converting each element of the
> array to a string, separated by the given separator.
Expected behavior according to the docs would be:
[ "a", [1, 2, [:x, :y]], "b" ].join("-") #=> "a-[1, 2, [:x, :y]]-b"
# because of:
[1, 2, [:x, :y]].to_s #=> "[1, 2, [:x, :y]]"
Actual behavior:
[ "a", [1, 2, [:x, :y]], "b" ].join("-") #=> "a-1-2-x-y-b"
because join is applied recursively for nested arrays.
The patch clarifies this behavior.
(Also: small markup and grammar fix.)
