+@item --no-ctf-variables
+The CTF debuginfo format supports a section which encodes the names and
+types of variables found in the program which do not appear in any symbol
+table. These variables clearly cannot be looked up by address by
+conventional debuggers, so the space used for their types and names is
+usually wasted: the types are usually small but the names are often not.
+@option{--ctf-variables} causes the generation of such a section.
+The default behaviour can be restored with @option{--no-ctf-variables}.

+@cindex ctf type sharing
+@kindex --ctf-share-types
+@item --ctf-share-types=@var{method}
+Adjust the method used to share types between translation units in CTF.
+
+@table @samp
+@item share-unconflicted
+Put all types that do not have ambiguous definitions into the shared dictionary,
+where debuggers can easily access them, even if they only occur in one
+translation unit. This is the default.
+
+@item share-duplicated
+Put only types that occur in multiple translation units into the shared
+dictionary: types with only one definition go into per-translation-unit
+dictionaries. Types with ambiguous definitions in multiple translation units
+always go into per-translation-unit dictionaries. This tends to make the CTF
+larger, but may reduce the amount of CTF in the shared dictionary. For very
+large projects this may speed up opening the CTF and save memory in the CTF
+consumer at runtime.

When PowerPC64 @command{ld} links input object files containing
relocations used on power10 prefixed instructions it normally creates
-linkage stubs (PLT call and long branch) using power10 instructions.
-In particular for @code{@@notoc} PLT calls where @code{r2} is not
-known the power10 stubs are smaller and faster, so are preferred for
+linkage stubs (PLT call and long branch) using power10 instructions
+for @code{@@notoc} PLT calls where @code{r2} is not known. The
+power10 notoc stubs are smaller and faster, so are preferred for
power10. @option{--power10-stubs} and @option{--no-power10-stubs}
allow you to override the linker's selection of stub instructions.
-For example, when linking a shared library that contains cpu-optimized
-versions of functions for both power9 and power10, you might use
-@option{--no-power10-stubs} so that power9 code making calls doesn't
-attempt to execute power10 instructions.
+@option{--power10-stubs=auto} allows the user to select the default
+auto mode.
