From 5874de95e8df1d051001cf53614c1d245c1ac5ae Mon Sep 17 00:00:00 2001 From: mame Date: Tue, 1 Jul 2008 16:55:30 +0000 Subject: * Add coverage measurement constant COVERAGE__. This constant is not for casual use. Usage: (1) assign {} to COVERAGE__, (2) require or load Ruby source file, and (3) COVERAGE__["sourcefilepath"] will return an array whose elements represent number of executions per line of source code. * vm_core.h: add field of coverage array to iseq. * iseq.c (prepare_iseq_build): ditto. * insns.def (trace): update coverage array. * parse.y (coverage): create and initialize coverage array. * compile.h (ADD_TRACE): add trace instruction to update covearge array. * thread.c (clear_coverage): delete coverage array when forking. Otherwise, double count of coverage may occur. * lib/coverage.rb: sample coverage measurement tool. * error.c: distinguish explicitly between parse_in_eval and mild_compile_error. * load.c: ditto. * vm_eval.c: ditto. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@17781 b2dd03c8-39d4-4d8f-98ff-823fe69b080e --- insns.def | 12 +++++++++++- 1 file changed, 11 insertions(+), 1 deletion(-) (limited to 'insns.def') diff --git a/insns.def b/insns.def index 161dc38e2e..96023a4adf 100644 --- a/insns.def +++ b/insns.def @@ -847,11 +847,21 @@ defined */ DEFINE_INSN trace -(rb_num_t nf) +(rb_num_t nf, VALUE coverage) () () { rb_event_flag_t flag = nf; + if (coverage) { + long line = rb_sourceline() - 1; + if (RARRAY_PTR(coverage)[line] == Qnil) { + rb_bug("bug"); + } + long count = FIX2LONG(RARRAY_PTR(coverage)[line]) + 1; + if (POSFIXABLE(count)) { + RARRAY_PTR(coverage)[line] = LONG2FIX(count); + } + } EXEC_EVENT_HOOK(th, flag, GET_SELF(), 0, 0 /* TODO: id, klass */); } -- cgit v1.2.3
