RFR(S) : 8219395 : integrate gcov w/ run-test

[Igor Ignatyev]

Hi Erik,

thanks for your review, I've removed the commented lines and changed default_make_targets, 
http://cr.openjdk.java.net/~iignatyev//8219395/webrev.0-1/index.html <http://cr.openjdk.java.net/~iignatyev//8219395/webrev.0-1/index.html> is incremental webrev.

Thanks,
-- Igor

I would recommend explicitly setting the default_make_targets (which would be product-bundles and test-bundles) for the new *-gcov profiles.
