I would like to request the backport of the fix for JDK-8011858 to 
8u-dev. The fix can help reducing the memory usage of the C2 compiler 
and is therefore needed to fix JDK-8129847.

Original (9) bug: https://bugs.openjdk.java.net/browse/JDK-8011858
Original changeset: 

Unfortunately, the fix does not apply cleanly, as two affected files are 
different in 9 and in 8u-dev. Here are the changes that I did not (could 
not) apply to the 8u-dev tree:
- http://hg.openjdk.java.net/jdk9/hs-comp/hotspot/rev/af60f1cb36f2#l6.8
- http://hg.openjdk.java.net/jdk9/hs-comp/hotspot/rev/af60f1cb36f2#l9.8

Webrev: http://cr.openjdk.java.net/~zmajo/8011858_8u/webrev.00/

- the fix was pushed into 9 on Aug 11 and did not cause any nightly 
- all JPRT tests pass;
- all JTREG tests pass that pass with the unmodified VM.

Thank you and best regards,
