Description
http://mail.openjdk.java.net/pipermail/hotspot-dev/2016-June/023637.html

HotSpot could not be built with misleading-indentation and shift-negative-value warining (error) on GCC 6.1.1 . 
And new SEGV and Internal Error are occurred.

So I think we have to fix new warnings and errors.
Comments
All subtasks have been closed. So I close this issue.

ILW = Build fails, with gcc 6, use alternate compiler = HLM = P3

Looking at Yasumasa's patch most of the issues seems to be in Compiler code so I assigned this to Compiler. Please create subtasks for Runtime and GC if all places are not fixed with a single patch.

This does not seem to be a build problem, but an issue with the Hotspot source code. Moving bug accordingly.

Priority needs to be reevaluated if this is to be fixed in JDK 9 post RDP1.
