RFR: 8236714: enable link-time section-gc for linux to remove unused code

[Baesken, Matthias]

Hi Magnus / David,  here is a new webrev :


http://cr.openjdk.java.net/~mbaesken/webrevs/8236714.4/


it supports now a  configure switch  --enable-linktime-gc=yes  that needs to be set  to enable the link time section gc  .

Exception is linuxs390x  where we already have the  feature enabled  (and keep it enabled always for LIB_JVM).

Best regards, Matthias

  *   Matthias: Have a look at some recently added option to get an indication of the best practice in adding new options. There are some ways to easily make this incorrect

Hi Magnus, do you have a good/”best practice”  example  (not that I catch a bad one 😉 )  ?

Best regards, Matthias
