From c08e8886badd47890a54bdc54f1c09de7ad5c8e8 Mon Sep 17 00:00:00 2001 From: mame Date: Wed, 20 Dec 2017 04:24:14 +0000 Subject: compile.c: add a RUBY_EVENT_COVERAGE_LINE event for line coverage 2.5's line coverage measurement was about two times slower than 2.4 because of two reasons; (1) vm_trace uses rb_iseq_event_flags (which takes O(n) currently where n is the length of iseq) to get an event type, and (2) RUBY_EVENT_LINE uses setjmp to call an event hook. This change adds a special event for line coverage, RUBY_EVENT_COVERAGE_LINE, and adds `tracecoverage` instructions where the event occurs in iseq. `tracecoverage` instruction calls an event hook without vm_trace. And, RUBY_EVENT_COVERAGE_LINE is an internal event which does not use setjmp. This change also cancells lineno change due to the deletion of trace instructions [Feature #14104]. So fixes [Bug #14191]. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@61350 b2dd03c8-39d4-4d8f-98ff-823fe69b080e --- vm_core.h | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'vm_core.h') diff --git a/vm_core.h b/vm_core.h index 374fcff1b2..d1c6cd6574 100644 --- a/vm_core.h +++ b/vm_core.h @@ -1755,7 +1755,8 @@ RUBY_SYMBOL_EXPORT_BEGIN int rb_thread_check_trap_pending(void); /* #define RUBY_EVENT_RESERVED_FOR_INTERNAL_USE 0x030000 */ /* from vm_core.h */ -#define RUBY_EVENT_COVERAGE_BRANCH 0x010000 +#define RUBY_EVENT_COVERAGE_LINE 0x010000 +#define RUBY_EVENT_COVERAGE_BRANCH 0x020000 extern VALUE rb_get_coverages(void); extern void rb_set_coverages(VALUE, int, VALUE); -- cgit v1.2.3
