+ * In order to let the DTrace fasttrap provider trace processes before libc
+ * is initialized, we place this structure in the thread pointer register.
+ * This is communicated to the kernel (in the elfexec() function) by
+ * placing the address of this structure in the PT_SUNWDTRACE program
+ * header with the -zdtrace_data=<object> option to ld(1).
+ *
+ * Besides DTrace use, the initialization sequence carried out for the
+ * PT_SUNWDTRACE data is an essential step required for the correct
+ * initialization of any process.  Therefore, PT_SUNWDTRACE data must
+ * exist in any interpretor available on Solaris.
+ *
+ * ld.so.1 is the standard interpretor on all Solaris platforms.  However,
+ * for ABI compliance, 32-bit executables are able to identify libc.so.1
+ * as their interpretor.  Therefore, this data file is used to build all
+ * instances of ld.so.1, and the 32-bit versions of libc.so.1.  Note,
+ * although libc.so.1 can act as an interpretor for 32-bit applications,
+ * libc.so.1 only provides a bootstrap mechanism to load and jump to
+ * ld.so.1.
+ *
+ * The fields of the program header are set as follows:
+ *	p_type:         PT_SUNWDTRACE
+ *	p_vaddr:        address of dtrace_data
+ *	p_memsz:        size of dtrace_data
+ *	p_flags:        flags of segment dtrace_data is assigned to
+ *	p_paddr:        <reserved>
+ *	p_filesz:       <reserved>
+ *	p_offset:       <reserved>
+ *	p_align:        <reserved>
+ *
+ * See the comment in fasttrap.h for information on how to safely change
+ * this data structure and the other places that need to be kept in sync.
