This patch adds some simple tests testing the support for DTrace USDT probes. The testsuite will be skipped as unsupported in case the user does not have DTrace installed on her system. The tests included in the test suite test breakpointing on DTrace probes, enabling and disabling probes, printing of probe arguments of several types and also breakpointing on several probes with the same name. gdb/ChangeLog: 2015-02-17 Jose E. Marchesi <jose.marchesi@oracle.com> * lib/dtrace.exp: New file. * gdb.base/dtrace-probe.exp: Likewise. * gdb.base/dtrace-probe.d: Likewise. * gdb.base/dtrace-probe.c: Likewise. * lib/pdtrace.in: Likewise. * configure.ac: Output variables with the transformed names of the strip, readelf, as and nm tools. AC_SUBST lib/pdtrace.in. * configure: Regenerated.
