@itemx --no-copy-dt-needed-entries
This option affects the treatment of dynamic libraries referred to
by DT_NEEDED tags @emph{inside} ELF dynamic libraries mentioned on the
-command line. Normally the linker will add a DT_NEEDED tag to the
+command line. Normally the linker won't add a DT_NEEDED tag to the
output binary for each library mentioned in a DT_NEEDED tag in an
-input dynamic library. With @option{--no-copy-dt-needed-entries}
+input dynamic library. With @option{--copy-dt-needed-entries}
specified on the command line however any dynamic libraries that
-follow it will have their DT_NEEDED entries ignored. The default
-behaviour can be restored with @option{--copy-dt-needed-entries}.

This option also has an effect on the resolution of symbols in dynamic
-libraries. With the default setting dynamic libraries mentioned on
-the command line will be recursively searched, following their
-DT_NEEDED tags to other libraries, in order to resolve symbols
-required by the output binary. With
-@option{--no-copy-dt-needed-entries} specified however the searching

+To refine the sections that are included based on the section flags
+of an input section, INPUT_SECTION_FLAGS may be used.
+
+Here is a simple example for using Section header flags for ELF sections:
+
+@smallexample
+@group
+SECTIONS @{
+ .text : @{ INPUT_SECTION_FLAGS (SHF_MERGE & SHF_STRINGS) *(.text) @}
+ .text2 : @{ INPUT_SECTION_FLAGS (!SHF_WRITE) *(.text) @}
+@}
+@end group
+@end smallexample
+
+In this example, the output section @samp{.text} will be comprised of any
+input section matching the name *(.text) whose section header flags
+@code{SHF_MERGE} and @code{SHF_STRINGS} are set. The output section
+@samp{.text2} will be comprised of any input section matching the name *(.text)
+whose section header flag @code{SHF_WRITE} is clear.

You can also specify files within archives by writing a pattern
matching the archive, a colon, then the pattern matching the file,
with no whitespace around the colon.
the veneer. The extra cycles required to call and return from the veneer
are sufficient to avoid the erratum in both the scalar and vector cases.
+@cindex ARM1176 erratum workaround
+@kindex --fix-arm1176
+@kindex --no-fix-arm1176
+The @samp{--fix-arm1176} switch enables a link-time workaround for an erratum
+in certain ARM1176 processors. The workaround is enabled by default if you
+are targetting ARM v6 (excluding ARM v6T2) or earlier. It can be disabled
+unconditionally by specifying @samp{--no-fix-arm1176}.
