Subject: sim: fix unused cpu_nr warnings
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=15f3c2de23e579e8965294c24de2a0bb5971273b;p=binutils-gdb.git

sim: fix unused cpu_nr warnings

The trace_option_handler() function only uses cpu_nr when the
SIM_HAVE_ADDR_RANGE define is enabled.  So move the decl down
to where the code exists.  Otherwise GCC warns:
sim-trace.c: In function 'trace_option_handler':
sim-trace.c:236: warning: unused variable 'cpu_nr'
