* mjit.c: fix obsoleted comment [ci skip]k0kubun2018-10-071-2/+2
| | | | git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@64931 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
* mjit.h: call compiled code immediatelyk0kubun2018-10-071-7/+11
| | | | | | | | | | | | | | | | | | | after the first compilation on --jit-wait. Previously the assignment to `func` didn't have meaning for the behavior, and the compiled code wasn't called immediately after the synchronous compilation. It wasn't intentional. Fixing this issue without impacting performance without --jit-wait is not so obvious. Adding branch or goto to call func in mjit_exec spoiled the performance without --jit-wait. Instead of that, I called the func inside mjit_wait_call() (former mjit_get_iseq_func()) which is never inlined to mjit_exec(). Thanks to that, this commit has no impact for normal performance. mjit.c: ditto git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@64929 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

* mjit.c: include mjit_worker.ck0kubun2018-08-111-29/+2
| | | | | | | | | | | | | | | instead of linking functions with mjit_worker.o. In the r64285's structure, we needed to publish some variables with mjit_ prefix. But ideally those variables should be completely private in mjit.o (or old mjit_worker.o), and it was hard. So I chose an approach similar to vm*.c for mjit.c and mjit_worker.c. I believe mjit_compile.c is still nice to be separated. After this commit, I'll remove the mjit_ prefix again... git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@64289 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

* mjit_worker.c: carve out worker-related codek0kubun2018-08-111-1136/+82
| | | | | | | | | | | | | | The motivation of this change is to make sure rb_funcall or GC-related functions are not called on worker-related code. Currently such functions are used in some places and I believe it's partly because it's hard to identify which part is called on MJIT worker thread. Now, mjit.c is safe to use them but we know we need to safely deal with mjit_compile.c, mjit_worker.c and mjit_internal.h. mjit_compile.c: update the comment about it git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@64285 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

| | | | | | | | | | | | | | | | when $MJIT_SEARCH_BUILD_DIR is set. If prefix path is owned by root, `make install` needs to be run by root. But in general we don't want to run `make test-all`, and also running `make test-all` currently fails due to permission tests of rdoc and rubygems. Thus, prior to this commit, specifying a prefix like "/usr/local" could mean there was no way to pass test-all. So we should not depend on `make install` for `make test-all`. Thus I reverted r64104 and r64103, and applied this workaround to pass `make test-all` without `make install`. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@64143 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

* mjit.c: introduce JIT compaction [experimental]k0kubun2018-07-281-13/+110
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When all compilation finishes or the number of JIT-ed code reaches --jit-max-cache, this compacts all generated code to a single .so file and re-loads all methods from it. In the future, it may trigger compaction more frequently and/or limit the maximum times of compaction to prevent unlimited memory usage. So the current behavior is experimental, but at least the performance improvement in this commit won't be removed. === Benchmark === In this benchmark, I'll compare following four conditions: * trunk: r64082 * trunk JIT: r64082 w/ --jit * single-so JIT: This commit w/ --jit * objfcn JIT: This branch https://github.com/k0kubun/ruby/tree/objfcn w/ --jit, which is shinh's objfcn https://github.com/shinh/ruby/tree/objfcn rebased from this commit ``` $ uname -a Linux bionic 4.15.0-29-generic #31-Ubuntu SMP Tue Jul 17 15:39:52 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux ``` * Micro benchmark Using this script https://gist.github.com/k0kubun/10e6d3387c9ab1b134622b2c9d76ef51, calls some amount of different methods that just return `nil`.

* mjit.c: split build stages for unixk0kubun2018-07-251-8/+53
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I'm going to build a large .so file that combines multiple .o files. For that change, I want to confirm the impact to performance by this change. So far, I haven't seen the significant change on the max performance. * before $ for i in 1 2 3 4 5 6 7 8 9 1 2; do ruby --jit ../../mame/optcarrot/bin/optcarrot --benchmark ../../mame/optcarrot/examples/Lan_Master.nes; done fps: 67.66058054621772 checksum: 59662 fps: 67.53138656233348 checksum: 59662 fps: 67.44109425628592 checksum: 59662 fps: 70.29423063961576 checksum: 59662 fps: 72.0147653358158 checksum: 59662 fps: 69.40157398157892 checksum: 59662 fps: 72.3984212467565 checksum: 59662 fps: 67.15473484463604 checksum: 59662 fps: 70.14142014098444 checksum: 59662 fps: 72.51761974327023 checksum: 59662 fps: 72.41086970333218 checksum: 59662 * after $ for i in 1 2 3 4 5 6 7 8 9 1 2; do ruby --jit ../../mame/optcarrot/bin/optcarrot --benchmark ../../mame/optcarrot/examples/Lan_Master.nes; done fps: 69.53134628999938 checksum: 59662 fps: 66.13157649232654 checksum: 59662 fps: 70.17474368971281 checksum: 59662 fps: 61.88316323809907 checksum: 59662 fps: 72.48731307319704 checksum: 59662 fps: 65.1180687907147 checksum: 59662 fps: 68.89553415996615 checksum: 59662 fps: 65.77342314036225 checksum: 59662 fps: 64.33337015048106 checksum: 59662 fps: 64.98152672793444 checksum: 59662 fps: 72.225729092625 checksum: 59662 git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@64052 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
* mjit.c: completely separate compile_c_to_sok0kubun2018-07-251-24/+38
| | | | | | | | | | | by whether on mswin or not. This is needed because I'm going to renew the compilation process for unix, keeping mswin builds as it is, at first. This commit is not changing the behavior at all. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@64051 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
* mjit.c: prevent memory leak on realloc failurek0kubun2018-07-251-2/+5

* mjit.c: handle memory allocation failurek0kubun2018-07-241-1/+4
| | | | | | | | | | | | | which was missing in r64033. Prior to r64033, memory allocation failure had been checked by TRY_WITH_GC and handled by rb_memerror. But calling rb_memerror on MJIT worker is problematic since it does EC_JUMP_TAG in the end. Threads except Ruby's main thread must not use it. mjit_compile.c: ditto git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@64037 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
* mjit.c: prevent GC on MJIT workerk0kubun2018-07-241-5/+5
| | | | | | | | | | mjit_compile.c: ditto. REALLOC_N, ALLOC_N and xmalloc trigger GC but it's not expected. Other allocation calls in mjit.c are executed on Ruby's main thread and thus fine. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@64033 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
* mjit: get rid of memory leak in pause+resume loopnormal2018-07-081-6/+8
| | | | | | | | | | | | | | | | | | pthread_atfork is not idempotent and repeatedly calling it causes it to register the same hook repeatedly; leading to unbound memory growth. Ruby already has a (confusing-named) internal API for to call in the forked child process: rb_thread_atfork Call the MJIT child_after_fork hook inside that to prevent unbound growth with the following loop: loop do RubyVM::MJIT.pause RubyVM::MJIT.resume end git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@63884 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
* mjit.c: fix waitpid macro return value for win32normal2018-07-061-1/+1
| | | | | | | | | | | We started checking return value of waitpid, so it needs to be correct for win32 platforms for MJIT to work.
