gdb/testsuite/gdb.base/fileio.c: gdb/testsuite/gdb.base/fileio.exp: 2007-12-08 Jan Kratochvil * gdb.base/fileio.c (ROOTSUBDIR): New macro. (main): CHDIR into ROOTSUBDIR. CHOWN ROOTSUBDIR and CHDIR into ROOTSUBDIR if we are being run as root. * gdb.base/fileio.exp: Change the startup and finish cleanup. Change the test file reference to be into the `fileio.dir' directory. sources/gdb/testsuite/gdb.base/dump.exp: Found on RHEL-5.s390x. gdb-6.8.50.20090209/gdb/testsuite/gdb.base/auxv.exp: random FAIL: gdb.base/auxv.exp: matching auxv data from live and gcore gdb-6.8.50.20090209/gdb/testsuite/gdb.base/annota1.exp: frames-invalid can happen asynchronously.
