nobu 490fbc4c85 hash.c: env block size limit on Windows
* hash.c (ruby_setenv): do not check environment block size.
  c.f. https://msdn.microsoft.com/en-us/library/windows/desktop/ms682653(v=vs.85).aspx
  Starting with Windows Vista and Windows Server 2008, there is no
  technical limitation on the size of the environment block.

tenderlove efee3033b5 Include Hash#size in the examples
Both methods Hash#length and Hash#size share the same source code in
Ruby, but they also share the same documentation. Now when you look at
the documentation of Hash#size you only see examples for Hash#length,
which is confusing. This commit includes Hash#size in the examples and
also remarks that both methods are equivalent to each other.

k0kubun ed935aa5be mjit_compile.c: merge initial JIT compiler
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.

NOTE: Rails performance was somehow a little degraded with JIT for now.
We should fix this.
(At least I know opt_aref is performing badly in JIT and I have an idea
 to fix it. Please wait for the fix.)

nobu 8880af9a3b Use UINT128_T support flag from configure
Current check for __uint128_t in hash.c is not valid, since it ignores
compilers other than gcc. We hit this on lcc on e2k platform.

Configure script properly checks from 128-bit data types support and
sets HAVE_UINT128_T accordingly. This approach is already used within
ruby at bignum.c, random.c, etc.

Probably hash.c is an overlooked remnant of old days. This patch fixes
this.

mame 0a6816ecd7 Revamp method coverage to support define_method
Traditionally, method coverage measurement was implemented by inserting
`trace2` instruction to the head of method iseq.  So, it just measured
methods defined by `def` keyword.

This commit drastically changes the measuring mechanism of method
coverage; at `RUBY_EVENT_CALL`, it keeps a hash from rb_method_entry_t*
to runs (i.e., it counts the runs per method entry), and at
`Coverage.result`, it creates the result hash by enumerating all
`rb_method_entry_t*` objects (by `ObjectSpace.each_object`).

shyouhei 0eb7359cc7 add rb_hash_new_with_size()
Sometimes, size of a hash can be calcluated a priori.  By providing
such info to the constructor we can avoid unnecessary internal re-
allocations.  This can boost for instance creation of hash literals.

normal d04c085b3c hash: keep fstrings of tainted strings for string keys
The same hash keys may be loaded from tainted data sources
frequently (e.g. parsing headers from socket or loading
YAML data from a file).  If a non-tainted fstring already
exists (because the application expects the hash key),
cache and deduplicate the tainted version in the new
tainted_frozen_strings table.

For non-embedded strings, this also allows sharing with the
underlying malloc-ed data.

normal e205304a3e Hash#[]= deduplicates string keys if (and only if) fstring exists
In typical applications, hash entries are read after being
written to.  Blindly writing to hashes which are never read
makes little sense. So, for any hash which is read from, an
fstring entry for the key should already exist for the key.

We no longer blindly create fstrings if the code is blindly
setting random hash keys, preventing the performance regression
in the reverted r43870.

Regarding <https://bugs.ruby-lang.org/issues/9188>, this has a
minimum impact on the bm_so_k_nucleotide where hash keys are set
and not reused, performance is within 1-2% of existing cases.

* hash.c: #include gc.h for rb_objspace_garbage_object_p
  (hash_aset_str): do read-only check of fstring table and
  reuse fstring if it exists and is still alive (not garbage)

watson1978 d0015e4ac6 Improve performance of implicit type conversion
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.

* st.c (rb_hash_bulk_insert): new API to bulk insert entries

	  This arrangement (rb_ prefixed function placed in st.c) is
	  unavoidable because it both touches table internal and write
	  barrier at once.

	* internal.h: delcare the new function.

	* hash.c (rb_hash_s_create): use the new function.

	* vm.c (core_hash_merge): ditto.
