I have been using `Hash#clear` to clear the constants, but that's because a `clear` method doesn't exist. I will add the following to the PR: ``` rb_define_singleton_method(rb_cRubyVM, "USAGE_ANALYSIS_INSN_CLEAR", usage_analysis_insn_clear, 0); rb_define_singleton_method(rb_cRubyVM, "USAGE_ANALYSIS_OPERAND_CLEAR", usage_analysis_operand_clear, 0); rb_define_singleton_method(rb_cRubyVM, "USAGE_ANALYSIS_REGISTER_CLEAR", usage_analysis_register_clear, 0); ``` ---------------------------------------- Feature #15963: Add *_start and *_running methods to VM_COLLECT_USAGE_DETAILS API https://bugs.ruby-lang.org/issues/15963#change-80417 * Author: gmcgibbon (Gannon McGibbon) * Status: Open * Priority: Normal * Assignee: ko1 (Koichi Sasada) * Target version: ---------------------------------------- I want to count how many VM instructions get executed for an arbitrary block of ruby code with `VM_COLLECT_USAGE_DETAILS` enabled. However, the current API enables VM usage detail collection immediately and only exposes methods to turn collection off. I've issued a PR to add more methods to the VM usage details API and to disable collection by default: https://github.com/ruby/ruby/pull/2258 -- https://bugs.ruby-lang.org/ Unsubscribe:
