+Solaris ELF files contain symbol sort sections used by DTrace to
+map addresses in memory to the related function or variable symbols. There
+are two such sections, \fI.SUNW_dynsymsort\fP for
+regular symbols, and \fI.SUNW_dyntlssort\fP for thread
+local symbols. To ensure that the best
+names are shown for each
+such address, and that the same name is given across Solaris releases,
+.I check_rtime
+enforces the rule that only one symbol can appear in the sort sections for
+any given address.
+There are two common ways in which multiple symbols
+or a given address occur in the ON distribution. The first is from
+code written in assembly language. The second is as a
+result of using \fB#pragma weak\fP in C to create weak symbols. The
+best solution to this
+situation is to modify the code to avoid symbol aliasing. Alternatively,
+the \fBNODYNSORT\fP mapfile attribute can be used to eliminate the unwanted
+symbol.
