# 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
