Hello Matthias,
You can keep the setting up of all the flags in flags-cflags.m4 and
flags-ldflags.m4 based on the value of ENABLE_LINKTIME_GC. You can also
default the value of this new parameter to true for s390x to keep the
current behavior for that platform. As it is in this patch, the JVM
flags for s390x are setup in configure while the JDK flags are in make,
which gets confusing I think.

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
