[PATCH, libjava]: Avoid suggest parentheses around comparison in operand of '|' in java/lang/natObject.cc

[Uros Bizjak]

Hello!

During libjava build, following warning is reported:

../../../gcc-svn/branches/gcc-4_8-branch/libjava/java/lang/natObject.cc:932:27:
warning: suggest parentheses around comparison in operand of '|'
[-Wparentheses]
    JvAssert(he -> address == address | LOCKED );
                           ^

It looks that parentheses are missing around (address | LOCKED),
otherwise the expression is always true - LOCKED is unconditionally
defined to 1. Attached patch adds these parentheses (and removes a
pair of superfluous ones).

2014-03-10  Uros Bizjak  <ubiz...@gmail.com>

    * java/lang/natObject.cc (_Jv_MonitorEnter): Add missing parenthesis
    around comparison with (address | LOCKED) in JvAssert.

Patch was bootstrapped and regression tested on x86_64-pc-linux-gnu {,-m32}.

OK for mainline SVN and release branches?

Uros.
