PRAGMA_FORMAT_MUTE_WARNINGS_FOR_GCC macro suppresses the following GCC warnings:

-Wformat
-Wformat-nonliteral
-Wformat-security

Its usage was removed in jdk9 in the following issues: JDK-8042893 , JDK-8042894, JDK-8042892 , which bring extensive changes and are unlikely to be good candidates for 8u backports.

I've verified, that this macro usage in share/vm/runtime/globals.cpp (that was changed in JDK-8280963 bugfix) is not necessary, at least on GCC 11 on Fedora this file can be compiled (after macro removal) without warnings. It is not clear whether it is the case with other versions of GCC.
