Revamp method coverage to support define_method

2017-12-05T07:16:42+00:00

Traditionally, method coverage measurement was implemented by inserting
`trace2` instruction to the head of method iseq.  So, it just measured
methods defined by `def` keyword.

This commit drastically changes the measuring mechanism of method
coverage; at `RUBY_EVENT_CALL`, it keeps a hash from rb_method_entry_t*
to runs (i.e., it counts the runs per method entry), and at
`Coverage.result`, it creates the result hash by enumerating all
`rb_method_entry_t*` objects (by `ObjectSpace.each_object`).

run-lcov.rb: wrongly used unique ID as lineno

2017-09-17T04:30:30+00:00

The second value of key of branch/method coverage is unique ID, not
lineno.

Measure branch and method coverage for `make test-all`

2017-09-14T06:07:05+00:00

To measure coverage of C code:
`./configure --enable-gcov && make && make exam && make lcov`

To measure coverage of Ruby code:
`./configure && make && make exam COVERAGE=true && make lcov`

To measure coverage of both languages at a time:
`./configure --enable-gcov && make && make exam COVERAGE=true && make lcov`

Support LCOV visualization for both C and Ruby code

2017-09-09T13:09:21+00:00

`./configure --enable-gcov && make exam && make lcov` will create
`lcov-c-out/index.html` for coverage of C code of the interpreter.
`make exam COVERAGE=true && make lcov` will create
`lcov-rb-out/index.html` for coverage of Ruby stdlib code.
Using both `--enable-gcov` and `COVERAGE=true` will create
`lcov-out/index.html` for total coverage.

Use lcov visualizer for gcov statistics

2017-07-04T16:02:19+00:00

This experimental feature is only for Ruby-core team, not for casual users.

Usage: `./configure --enable-gcov && make && make exam && make lcov`
