YJIT: Let RubyVM::YJIT.enable respect --yjit-stats
2023-12-19YJIT: Add stats option to RubyVM::YJIT.enable (#9297)Takashi Kokubun
2023-11-28YJIT: fix bug in top cfunc logging in `--yjit-stats` (#9056)Maxime Chevalier-Boisvert
YJIT: correctly handle case where there are no cfunc calls Fix bug in top cfunc logging in `--yjit-stats`
2023-11-27YJIT: add top C function call counts to `--yjit-stats` (#9047)Maxime Chevalier-Boisvert
* YJIT: gather call counts for individual cfuncs Co-authored by Takashi Kokubun
2023-11-23YJIT: record `num_send_cfunc` stat (#9022)Maxime Chevalier-Boisvert
* YJIT: record num_send_cfunc stat Also report num_send_known_cfunc as percentage of num_send_cfunc * Rename num_send_known_cfunc => num_send_cfunc_inline Name seems more descriptive of what we do with out custom codegen
2023-11-10[DOC] RubyVM::YJIT doc improvementsAlan Wu
* Weaken notice about API stability. A few public APIs in here now. * Prune out APIs from the docs that are private in nature * Enable markdown mode and ensure `--` options are quoted so they are rendered as two dashes in the HTML.
2023-11-08YJIT: refactor format_number (#8869)Mau Magnaguagno
Replace enumerators with simpler and faster version that only inserts commas before '.' or end of integer string.
2023-11-07YJIT: Inline basic Ruby methods (#8855)Takashi Kokubun
* YJIT: Inline basic Ruby methods * YJIT: Fix "InsnOut operand made it past register allocation" checktype should not generate a useless instruction.
2023-11-01YJIT: skip to_a in format_number (#8815)Mau Magnaguagno
String#chars returns an array instead of an enumerator since Ruby 2.0.
2023-10-19YJIT: Print exit reasons on failure in test_yjit.rbAlan Wu
For <https://bugs.ruby-lang.org/issues/19921>, I suspect the test is failing due to a timing related interrupt, which on paper could happen with slow-enough GC runs. In any case, it's helpful for debugging to have more information when tests fail. Co-authored-by: Takashi Kokubun <takashikkbn@gmail.com>
2023-10-19YJIT: Add RubyVM::YJIT.enable (#8705)Takashi Kokubun
2023-10-18YJIT: Add a live ISeq counter Alan Wu

2023-10-17YJIT: Add a few missing counters for send fallback (#8681)Takashi Kokubun
2023-10-12YJIT: port call threshold logic from Rust to C for performance (#8628)Maxime Chevalier-Boisvert
* Port call threshold logic from Rust to C for performance * Prefix global/field names with yjit_ * Fix linker error * Fix preprocessor condition for rb_yjit_threshold_hit * Fix third linker issue * Exclude yjit_calls_at_interv from RJIT bindgen --------- Co-authored-by: Takashi Kokubun <takashikkbn@gmail.com>
2023-10-03YJIT: add heuristic to avoid compiling cold ISEQs (#8522)Maxime Chevalier-Boisvert
* YJIT: Add counter to measure how often we compile "cold" ISEQs (#535) Fix counter name in DEFAULT_COUNTERS YJIT: add --yjit-cold-threshold, don't compile cold ISEQs YJIT: increase default cold threshold to 200_000 Remove rb_yjit_call_threshold() Remove conflict markers Fix compilation errors Threshold 1 should compile immediately Debug deadlock issue with test_ractor Fix call threshold issue with tests * Revert exception threshold logic. Document option in yjid.md * (void) for 0 parameter functions in C99 * Rename iseq_entry_cold => cold_iseq_entry * Document --yjit-cold-threshold in ruby.c * Update doc/yjit/yjit.md Co-authored-by: Jean byroot Boussier <jean.boussier+github@shopify.com> * Shorten help string to appease test * Address bug found by Kokubun.

2023-04-24YJIT: Show definedivar exit reasons (#7755)Takashi Kokubun
Notes: Merged-By: k0kubun <takashikkbn@gmail.com>
2023-04-18YJIT: Fix raw sample stack lengths in exit traces (#7728)John Hawthorn
yjit-trace-exits appends a synthetic sample for the instruction being exited, but we didn't increment the size of the stack. Fixing this count correctly lets us successfully generate a flamegraph from the exits. I also replaced the line number for instructions with 0, as I don't think the previous value had meaning. Co-authored-by: Adam Hess <HParker@github.com> Notes: Merged-By: maximecb <maximecb@ruby-lang.org>
2023-04-14YJIT: Add a counter to all side exits (#7720)Takashi Kokubun
Notes: Merged-By: maximecb <maximecb@ruby-lang.org>
2023-04-13YJIT: Fix edge and total counts in exit_locations (#7702)John Hawthorn
The stackprof-format raw samples are suffixed with a count (ie. how many times did the previously recorded side-exit repeat). Previously we were correctly using this value to increment the :samples count, but not the :total_samples count or edges. This made the stackprof aggregate results incorrect (though any flamegraphs generated should have been correct, since those only rely on raw samples).

2023-03-28YJIT: Add `--yjit-pause` and `RubyVM::YJIT.resume` (#7609)Maxime Chevalier-Boisvert
* YJIT: Add --yjit-pause and RubyVM::YJIT.resume This allows booting YJIT in a suspended state. We chose to add a new command line option as opposed to simply allowing YJIT.resume to work without any command line option because it allows for combining with YJIT tuning command line options. It also simpifies implementation. Paired with Kokubun and Maxime. * Update yjit.rb Co-authored-by: Takashi Kokubun <takashikkbn@gmail.com> --------- Co-authored-by: Alan Wu <XrXr@users.noreply.github.com> Co-authored-by: Takashi Kokubun <takashikkbn@gmail.com> Notes: Merged-By: maximecb <maximecb@ruby-lang.org>
2023-03-17YJIT: skip intermediate arrays in print_sorted_exit_counts (#7547)Mau Magnaguagno
