| | | | | | | | | | | | | | * compile.c (iseq_compile_each0): insert to_s method call, so that refinements activated at the caller should take place. [Feature #13812] * insns.def (tostring): fix up converted object to a string, infect and fallback. * insns.def (branchiftype): new instruction for conversion. branches if TOS is an instance of the given type. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@59950 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

* Remove unneeded trace instruction for coveragemame2017-09-071-0/+5
| | | | | | | | | | | | | | When no instruction is emitted in `iseq_compile_each0` (i.e., when the line has no significant code), trace instruction for `RUBY_EVENT_LINE` has been optimized out. But trace for `RUBY_EVENT_COVERAGE` has not been removed. Now, it is also removed. `TestISeq#test_to_a_lines` has failed a long time under coverage measurement (`make test-all COVERAGE=true`). This change makes it pass. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@59769 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
* Refactor the internal data format for coverage measurementmame2017-09-031-1/+2
| | | | | | | | | | | To prepare new measuring targets: branch and method coverages. So far, iseq->coverage was an array of counts executed for line coverage. Now, it is a three-element array for each measuring target, whose first element is an array for line coverage. The second element is planned for branch coverage, and the third will be for method coverage. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@59738 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
