Maciej W. Rozycki 0726fcc61a testsuite: Fix a `server_pid' access crash in gdb.server/server-kill.exp ... Fix a commit f90183d7e3 ("Get GDBserver pid on remote target") bug and correctly handle the case where the PID of `gdbserver' could not have been retrieved. If that happens, $server_pid is unset causing: FAIL: gdb.server/server-kill.exp: p server_pid ERROR: tcl error sourcing .../gdb/testsuite/gdb.server/server-kill.exp. ERROR: can't read "server_pid": no such variable while executing "if {$server_pid == "" } { return -1 }" (file ".../gdb/testsuite/gdb.server/server-kill.exp" line 49) invoked from within "source .../gdb/testsuite/gdb.server/server-kill.exp" ("uplevel" body line 1) invoked from within "uplevel #0 source .../gdb/testsuite/gdb.server/server-kill.exp" invoked from within "catch "uplevel #0 source $test_file_name"" Verify that the variable exists then rather than trying to access it. gdb/testsuite/ * gdb.server/server-kill.exp: Verify whether `server_pid' exists rather then trying to access it in determining whether the PID of `gdbserver' could have been retrieved.		2018-05-15 15:54:36 +01:00
