Make test names unique in the gdb.reverse tests. On my local machine this removed 825 duplicate test names. It is possible that different setups might still encounter some duplicates. gdb/testsuite/ChangeLog: * gdb.reverse/break-precsave.exp: Make test names unique. * gdb.reverse/break-reverse.exp: Likewise. * gdb.reverse/finish-precsave.exp: Likewise. * gdb.reverse/finish-reverse.exp: Likewise. * gdb.reverse/machinestate-precsave.exp: Likewise. * gdb.reverse/machinestate.exp: Likewise. * gdb.reverse/readv-reverse.exp: Likewise. * gdb.reverse/recvmsg-reverse.exp: Likewise. * gdb.reverse/sigall-precsave.exp: Likewise. * gdb.reverse/sigall-reverse.exp: Likewise. * gdb.reverse/step-indirect-call-thunk.exp: Likewise. * gdb.reverse/watch-precsave.exp: Likewise. * gdb.reverse/watch-reverse.exp: Likewise.

# register variable

# function static variable
|
