From cdd77289afc9e2b18f33bed1c4ecb1d3e02bd8f0 Mon Sep 17 00:00:00 2001 From: mame Date: Tue, 9 Jan 2018 06:17:21 +0000 Subject: compile.c (iseq_compile_each0): remove irrelevant tracecoverage This change removes tracecoverage instructions on a line that has any NODE but is non-significant, such as, just one literal. This fixes the following failure that occurs only when coverage is enabled: 1) Failure: TestISeq#test_to_a_lines [.../ruby/test/ruby/test_iseq.rb:56]: <[3, 4, 7, 9]> expected but was <[3, 4, 5, 6, 7, 8, 9]>. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@61711 b2dd03c8-39d4-4d8f-98ff-823fe69b080e --- compile.c | 12 ++++++++++++ 1 file changed, 12 insertions(+) diff --git a/compile.c b/compile.c index 3d94cf1bad..6d9d0f4180 100644 --- a/compile.c +++ b/compile.c @@ -7169,6 +7169,18 @@ iseq_compile_each0(rb_iseq_t *iseq, LINK_ANCHOR *const ret, const NODE *node, in return COMPILE_NG; } + /* remove tracecoverage instruction if there is no relevant instruction */ + if (IS_TRACE(ret->last) && ((TRACE*) ret->last)->event == RUBY_EVENT_LINE) { + LINK_ELEMENT *insn = ret->last->prev; + if (IS_INSN(insn) && + IS_INSN_ID(insn, tracecoverage) && + FIX2LONG(OPERAND_AT(insn, 0)) == RUBY_EVENT_COVERAGE_LINE + ) { + ELEM_REMOVE(insn); /* remove tracecovearge */ + RARRAY_ASET(ISEQ_LINE_COVERAGE(iseq), line - 1, Qnil); + } + } + debug_node_end(); return COMPILE_OK; } -- cgit v1.2.3
