Author: Hao Sun (shqking) Date: 2021-04-27T09:46:42Z Commit: https://github.com/php/php-src/commit/a8b19a00c44b3ed7d65b1d2efd0defdbdd032aa3 Raw diff: https://github.com/php/php-src/commit/a8b19a00c44b3ed7d65b1d2efd0defdbdd032aa3.diff Support ZEND_JIT_ON_HOT_COUNTERS mode This patch implements stub functions zend_jit_hybrid_hot_code_stub() and zend_jit_hybrid_hot_counter_stub(), which is needed by HOT COUNTER mode, i.e. 'opcache.jit=123x'. Test case "defined_001.phpt" can pass now since HOT COUNTER mode is required by this case.
