Despite that this will not cause a build failure even on the default configuration (with "--enable-werror"), it is better to be fixed. The cause of this warning, sim/frv/sem.c is generated by CGEN from cpu/frv.cpu. This commit adds initialization of some variables that caused GCC warnings. cpu/ChangeLog: * frv.cpu (cmpb): Initialize cc variable.
