2017-07-04tool/run-gcov.rb: ignore rubyspec_temp directorymame
rubyspec compiles the extension libraries for capi specs in a temporary directory, and after that, deletes the directory. gcov resurrects the directory to save coverage statistics (.gcda files). However, the source and profiling artifacts (.gcno files) have been deleted. So, we need to ignore the .gcda files. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@59260 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2017-05-20Add coverage measurement mode by using gcovmame
This experimental feature is only for Ruby-core team, not for casual users. Usage: `./configure --enable-gcov && make && make exam && make gcov` git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@58817 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
