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.

# Generate a test program containing DTrace USDT probes, whose sources
|
|
# are ${srcfile} and ${testfile}.d. The sequence of commands used to
|
|
# generate the test program is:
|
|
#
|
|
# 1. Generate a header file from ${testfile}.d using dtrace -h.
|
|
# 2. Compile ${srcfile}.c.
|
|
# 3. Generate an object file containing a DOF program using dtrace -G.
|
|
# 4. Link everything together to get the test program.
|
|
#
|
|
# Note that if DTrace is not found in the host system then this
|
|
# function uses the pdtrace implementation, which is located at
|
|
# testsuite/lib/pdtrace.
|
|
#
|
|
# This function requires 'testfile', 'srcfile' and 'binfile' to be
|
|
# properly set.
|
|
#
|
|
# This function returns -1 on failure, 0 otherwise
