This patch removes all special cases for HP-UX, for which support has been removed earlier, that I found in the testsuite. Note that the hppa architecture != HP-UX, since other OSes can run on hppa, so I tried to leave everything that is not HP-UX specific. Two complete tests were completely HP-UX specific, so I removed them. I ran the testsuite on Linux x86-64, native and native-gdbserver, and noticed no regressions. gdb/testsuite/ChangeLog: * gdb.asm/asm-source.exp: Remove HP-UX references. * gdb.base/annota1.exp: Likewise. * gdb.base/annota3.exp: Likewise. * gdb.base/attach.exp: Likewise. * gdb.base/bigcore.exp: Likewise. * gdb.base/break.exp: Likewise. * gdb.base/call-ar-st.exp: Likewise. * gdb.base/callfuncs.exp: Likewise. * gdb.base/catch-fork-static.exp: Likewise. * gdb.base/display.exp: Likewise. * gdb.base/foll-exec-mode.exp: Likewise. * gdb.base/foll-exec.exp: Likewise. * gdb.base/foll-fork.exp: Likewise. * gdb.base/foll-vfork.exp: Likewise. * gdb.base/funcargs.exp: Likewise. * gdb.base/hbreak2.exp: Likewise. * gdb.base/inferior-died.exp: Likewise. * gdb.base/interrupt.exp: Likewise. * gdb.base/multi-forks.exp: Likewise. * gdb.base/nodebug.exp: Likewise. * gdb.base/sepdebug.exp: Likewise. * gdb.base/solib1.c: Likewise. * gdb.base/step-test.exp: Likewise. * gdb.mi/non-stop.c: Likewise. * gdb.mi/pthreads.c: Likewise. * gdb.multi/bkpt-multi-exec.ex: Likewise. * gdb.threads/pthreads.c: Likewise. * gdb.threads/staticthreads.exp: Likewise. * lib/future.exp: Likewise. * lib/gdb.exp: Likewise. * gdb.base/so-indr-cl.c: Remove. * gdb.base/so-indr-cl.exp: Likewise. * gdb.base/solib.c: Likewise. * gdb.base/solib.exp: Likewise. * gdb.base/solib2.c: Likewise.
