This makes more changes in gdb.base to make it parallel-safe. I think the changes in this particular patch are relatively straightforward, so I've grouped them all together. 2013-11-04 Tom Tromey <tromey@redhat.com> * gdb.base/advance.exp: Use standard_testfile and prepare_for_testing. * gdb.base/bigcore.exp: Use standard_output_file. "cd" to appropriate directory when local. * gdb.base/dump.exp: Use standard_output_file. Update all "dump" and "restore" filenames. * gdb.base/interact.exp: Use standard_output_file. * gdb.base/jit-so.exp: Don't download file when local. * gdb.base/jit.exp (compile_jit_test): Don't download file when local. * gdb.base/list.exp: Use gdb_remote_download. * gdb.base/maint.exp: Use standard_output_file. * gdb.base/prelink.exp: Use standard_output_file. * gdb.base/save-bp.exp: Use standard_output_file. * gdb.base/sepdebug.exp: Use standard_testfile, standard_output_file. (test_different_dir): Don't declare objdir. * gdb.base/solib-search.exp: Use standard_output_file. * gdb.base/step-line.exp: Use gdb_remote_download. * gdb.base/trace-commands.exp: Use standard_output_file.
