Convert the dtrace(1) man page to mdoc and fix up some aspects of it that
don't make sense on FreeBSD. In particular, - remove the ATTRIBUTES section, - remove references to the Solaris Dynamic Tracing Guide, except in the SEE ALSO section, - update the description of the -A option for FreeBSD's implementation, - remove references to Solaris-specific programs and configuration files, and replace them with FreeBSD equivalents where possible. The content has not changed aside from this. Approved by: re (joel) MFC after: 1 week

The following options are supported:

-\fB\fB-32\fR | \fB-64\fR\fR
-.ad
-.sp .6
-.RS 4n
-The D compiler produces programs using the native data model of the operating system kernel. You can use the \fBisainfo\fR \fB-b\fR command to determine the current operating system data model. If the \fB-32\fR option is specified, \fBdtrace\fR forces
-the D compiler to compile a D program using the 32-bit data model. If the \fB-64\fR option is specified, \fBdtrace\fR forces the D compiler to compile a D program using the 64-bit data model. These options are typically not required as \fBdtrace\fR selects the
-native data model as the default. The data model affects the sizes of integer types and other language properties. D programs compiled for either data model can be executed on both 32-bit and 64-bit kernels. The \fB-32\fR and \fB-64\fR options also determine the ELF file format
-(ELF32 or ELF64) produced by the \fB-G\fR option.
-.RE
-
-.sp

-.mk

-\fB\fB-a\fR\fR
-.ad
-.sp .6
-.RS 4n
-Claim anonymous tracing state and display the traced data. You can combine the \fB-a\fR option with the \fB-e\fR option to force \fBdtrace\fR to exit immediately after consuming the anonymous tracing state rather than continuing to wait for new
-data. See the \fISolaris Dynamic Tracing Guide\fR for more information about anonymous tracing.
-.RE

-.sp
-.ne 2
-.mk
-.na
-\fB\fB-A\fR\fR
-.ad
-.sp .6
-.RS 4n
-Generate \fBdriver.conf\fR(4) directives for anonymous tracing. This option constructs a set of \fBdtrace\fR(7D) configuration file directives to enable the specified probes for anonymous tracing and then exits. By default, \fBdtrace\fR attempts to store the directives to the file \fB/kernel/drv/dtrace.conf\fR. You can modify this behavior if you use the \fB-o\fR option to specify an alternate output file.
-.RE

-.sp
-.ne 2
-.mk
-.na
-\fB\fB-b\fR \fIbufsz\fR\fR
-.ad
-.sp .6
-.RS 4n
-Set principal trace buffer size (\fIbufsz\fR). The trace buffer size can include any of the size suffixes \fBk\fR, \fBm\fR, \fBg\fR, or \fBt\fR. If the buffer space cannot be allocated, \fBdtrace\fR attempts
-to reduce the buffer size or exit depending on the setting of the \fBbufresize\fR property.
-.RE

-.mk
-.na
-\fB\fB-c\fR \fIcmd\fR\fR
-.ad
-.sp .6
-.RS 4n
-Run the specified command \fIcmd\fR and exit upon its completion. If more than one \fB-c\fR option is present on the command line, \fBdtrace\fR exits when all commands have exited, reporting the exit status for each child process as it
-terminates. The process-ID of the first command is made available to any D programs specified on the command line or using the \fB-s\fR option through the \fB$target\fR macro variable. Refer to the \fISolaris Dynamic Tracing Guide\fR for more information
-on macro variables.

-.ne 2
-.mk
-.na
-\fB\fB-C\fR\fR
-.ad
-.sp .6
-.RS 4n
-Run the C preprocessor \fBcpp\fR(1) over D programs before compiling them. You can pass options to the C preprocessor using the \fB-D\fR, \fB-U\fR, \fB-I\fR, and \fB-H\fR options. You can select the degree of C standard conformance if you use the \fB-X\fR option. For a description of the set of tokens defined by the D compiler when invoking the C preprocessor, see \fB-X\fR.

-Define \fIname\fR when invoking \fBcpp\fR(1) (enabled using the \fB-C\fR option). If you specify the equals sign (\fB=\fR)
-and additional \fIvalue\fR, the name is assigned the corresponding value. This option passes the \fB-D\fR option to each \fBcpp\fR invocation.
-.RE

-.mk
-.na
-\fB\fB-e\fR\fR
-.ad
-.sp .6
-.RS 4n
-Exit after compiling any requests and consuming anonymous tracing state (\fB-a\fR option) but prior to enabling any probes. You can combine this option with the \fB-a\fR option to print anonymous tracing data and exit. You can also combine this option with D
-compiler options. This combination verifies that the programs compile without actually executing them and enabling the corresponding instrumentation.
