* 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. Reorder logic. --------- Co-authored-by: Alan Wu <XrXr@users.noreply.github.com> Co-authored-by: Jean byroot Boussier <jean.boussier+github@shopify.com>
