2018-05-03_mjit_compile_send.erb: retry inlining attr_readerk0kubun
This reverts r63249 (revert r63212) and fixes a bug in it. The test to prevent the bug is added as well. vm_insnhelper.c: add `index` argument to vm_getivar. The argument is created so that MJIT can pass the value of `cc->aux.index` on compilation time. The cache invalidation in _mjit_compile_send_guard.erb is only working for the cache value on compilation time. Note: As `index` is always passed as constant and it's force-inlined, the performance of `vm_getivar` won't be degraded in VM. _mjit_compile_send_guard.erb: New. Used to invalidate inlined values of cc. common.mk: update dependencies for _mjit_compile_send_guard.erb git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@63333 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2018-03-09Add direct marking on iseq operandstenderlove
Directly marking iseq operands allows us to eliminate the "mark array" stored on ISEQ objects, which will reduce the amount of memory ISEQ objects consume. This patch changes the iseq mark function to: * Directly marks ISEQ operands * Iterate over and mark child ISEQs It also introduces two flags on the ISEQ object. In order to mark instruction operands, we have to disassemble the instructions and find the instruction parameters and types. Instructions may also be translated to jump addresses. Instruction sequences may get marked by the GC *while* they're mid flight (being compiled). The `ISEQ_TRANSLATED` flag is used to indicate whether or not the instructions have been translated to jump addresses so that when we decode the instructions we know whether or not we need to go from jump location back to original instruction or not. Not all ISEQ objects have any markable objects embedded in their instructions. We can detect whether or not an ISEQ has markable objects in the instructions at compile time. If the instructions contain markable objects, we set a flag `ISEQ_MARKABLE_ISEQ` on the ISEQ object. This means that during the mark phase, we can skip decompilation if the flag is *not* set. In other words, we can avoid decompilation of we know in advance there is nothing to mark. `once` instructions have an operand that contains the result of a one-time compilation of a regex. Before this patch, that operand was called an "inline cache", even though the struct was actually an "inline storage". This patch changes the operand to be an "inline storage" so that we can differentiate between caches that need marking (the inline storage) and caches that don't need marking (inline cache).

2018-03-04mjit_compile.c: use local variables for stackk0kubun
if catch_except_p is FALSE. If catch_except_p is TRUE, stack values should be on VM's stack when exception is thrown and the JIT-ed frame is re-executed by VM's exception handler. If it's FALSE, the JIT-ed frame won't be re-executed and don't need to keep values on VM's stack. Using local variables allows us to reduce cfp->sp motion. Moving cfp->sp is needed only for insns whose handles_frame? is false. So it improves performance. _mjit_compile_insn.erb: Prepare `stack_size` variable for GET_SP, STACK_ADDR_FROM_TOP, TOPN macros. Share pc and sp motion partial view. Use cancel handler created in mjit_compile.c. _mjit_compile_send.erb: ditto. Also, when iseq->body->catch_except_p is TRUE, this stops to call mjit_exec directly. I described the reason in vm_insnhelper.h's comment for EXEC_EC_CFP. _mjit_compile_pc_and_sp.erb: Shared logic for moving sp and pc. As you can see from thsi file, when status->local_stack_p is TRUE and insn.handles_frame? is false, moving sp is skipped. But if insn.handles_frame? is true, values should be rolled back to VM's stack. common.mk: add dependency for the file _mjit_compile_insn_body.erb: Set sp value before canceling JIT on DISPATCH_ORIGINAL_INSN. Replace GET_SP, STACK_ADDR_FROM_TOP, TOPN macros for the case ocal_stack_p is TRUE and insn.handles_frame? is false. In that case, values are not available on VM's stack and those macros should be replaced. mjit_compile.inc.erb: updated comments of macros which are supported by JIT compiler. All references to `cfp->sp` should be replaced and thus INC_SP, SET_SV, PUSH are no longer supported for now, because they are not used now. vm_exec.h: moved EXEC_EC_CFP definition to vm_insnhelper.h because it's tighly coupled to CALL_METHOD. vm_insnhelper.h: Have revised EXEC_EC_CFP definition moved from vm_exec.h. Now it triggers mjit_exec for VM, and has the guard for catch_except_p on JIT-ed code. See comments for details. CALL_METHOD delegates triggering mjit_exec to EXEC_EC_CFP. insns.def: Stopped using EXEC_EC_CFP for the case we don't want to trigger mjit_exec. Those insns (defineclass, opt_call_c_function) are not supported by JIT and it's safe to use RESTORE_REGS(), NEXT_INSN(). expandarray is changed to pass GET_SP() to replace the macro in _mjit_compile_insn_body.erb. vm_insnhelper.c: change to take sp for the above reason.

It's not improved so much, but it would be effective when we achieve Ruby method inlining in _mjit_compile_send.erb. * Micro benchmark Given the following bench.rb, ``` class HashWithIndifferentAccess < Hash def []=(key, value) super(key.to_s, value) end def [](key) super(key.to_s) end end indhash = HashWithIndifferentAccess.new indhash[:foo] = 'bar' key = 'foo' 100000000.times do indhash[key] end ``` ** before ``` $ time ./ruby --disable-gems --jit-verbose=1 /tmp/bench.rb JIT success (31.4ms): block in <main>@/tmp/bench.rb:15 -> /tmp/_ruby_mjit_p18206u0.c JIT success (669.3ms): []@/tmp/bench.rb:6 -> /tmp/_ruby_mjit_p18206u1.c Successful MJIT finish ./ruby --disable-gems --jit-verbose=1 /tmp/bench.rb 12.21s user 0.04s system 107% cpu 11.394 total ``` ** after ``` $ time ./ruby --disable-gems --jit-verbose=1 /tmp/bench.rb JIT success (41.0ms): block in <main>@/tmp/bench.rb:15 -> /tmp/_ruby_mjit_p17293u0.c JIT success (679.0ms): []@/tmp/bench.rb:6 -> /tmp/_ruby_mjit_p17293u1.c Successful MJIT finish ./ruby --disable-gems --jit-verbose=1 /tmp/bench.rb 11.54s user 0.06s system 108% cpu 10.726 total ``` The execution time is shortened. * optcarrot benchmark Optcarrot has no room to be improved by this change.

2018-02-04mjit_compile.c: merge initial JIT compilerk0kubun
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.

Now that sp_inc attributes are officially provided as inline functions. Why not use them directly from the vm core, not just by the compiler. By doing so, it is now possible for us to optimize stack manipulations. We can now know exactly how many words of stack space an instruction consumes before it actually does. This changeset deletes some lines from insns.def because they are no longer needed. As a result it reduces the size of vm_exec_core function from 32,400 bytes to 32,352 bytes on my machine.

Previous commit changed insns.def format. Now is the time for its generators. In doing so I chose to modernize the system, not just patch. My attempt includes - extensive use of Onigumo regular expressions - split from one big file (instruction.rb) into separated MVC - partial view Also, let me take this opportunity to kill old unused features such as - stack caching - minsns / yasmdata which are never seriously used - yarvarch document generation (moved to doc/) - vast majority of unused arguments to insns2vm.rb This commit generates VM source codes that cleanly compile, and the generated binary passes tests. At least for me. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@61784 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
