- Subject: [gdbserver] Remove unused variables
Hi,
This patch is to remove unused variables in order to fix some build
failures I find today on GDB CVS HEAD.
gdb-mainline/gdb/gdbserver/server.c: In function 'start_inferior':
gdb-mainline/gdb/gdbserver/server.c:276:14: error: variable 'ptid' set
but not used [-Werror=unused-but-set-variable]
gdb-mainline/gdb/gdbserver/server.c: In function
'queue_stop_reply_callback':
gdb-mainline/gdb/gdbserver/server.c:2158:32: error: variable 'status'
set but not used [-Werror=unused-but-set-variable]
Tested on X86-64 native build. No regressions.
