Hello all;
This is a final update to the previously reviewed changeset. I had to make one
slight change in hotspot/src/os/bsd/vm/os_bsd.cpp to accommodate a problem
which appeared since this process began.
http://cr.openjdk.java.net/~mduigou/JDK-8030350/5/webrev/
This change will be integrated through the jdk9/hs-rt repos.
From the original review request:
This is a change which enables additional compiler warnings for native
compilation when using GCC. The (-Wformat -Wformat-security) options are
supported by GCC 3.0.4 (the earliest version I checked, c. February 2002) and
later so we shouldn't see issues with incompatibility.- Wextra appears to have
been added in GCC 3.4.X line (c. 2004) so it should also be reasonably well
adopted and replaces -W.
The core of the change is to add :
-Wextra -Wno-unused -Wno-unused-parameter -Wformat=2
for general C and CC++ compilations. For HotSpot C++ compiles a slightly less
aggressive set is used:
-Wformat=2 -Wno-error=format-nonliteral
is used.
This change is targeted at the JDK 9 repos but could be backported to JDK 8
fairly easily/safely.
Mike
