-@command{nlmconv} converts the relocatable @samp{i386} object file

-@var{infile};
-@ifclear man
-see @ref{BFD,,BFD,ld.info,Using LD}, for more information.
-@end ifclear
-
-@command{nlmconv} can perform a link step. In other words, you can list
-more than one object file for input if you list them in the definitions

+@command{elfedit} updates the ELF header and program property of ELF
+files which have the matching ELF machine and file types. The options
+control how and which fields in the ELF header and program property
+should be updated.
@var{elffile}@dots{} are the ELF files to be updated. 32-bit and
64-bit ELF files are supported, as are archives containing ELF files.
The long and short forms of options, shown here as alternatives, are
equivalent. At least one of the @option{--output-mach},
-@option{--output-type} and @option{--output-osabi} options must be given.
+@option{--output-type}, @option{--output-osabi},
+@option{--enable-x86-feature} and @option{--disable-x86-feature}
+options must be given.
@table @env
Change the ELF OSABI in the ELF header to @var{osabi}. The
supported ELF OSABI are the same as @option{--input-osabi}.
+@item --enable-x86-feature=@var{feature}
+Set the @var{feature} bit in program property in @var{exec} or @var{dyn}
+ELF files with machine types of @var{i386} or @var{x86-64}. The
+supported features are, @var{ibt} and @var{shstk}.
+
+@item --disable-x86-feature=@var{feature}
+Clear the @var{feature} bit in program property in @var{exec} or
+@var{dyn} ELF files with machine types of @var{i386} or @var{x86-64}.
+The supported features are the same as @option{--enable-x86-feature}.
+
+Note: @option{--enable-x86-feature} and @option{--disable-x86-feature}
+are available only on hosts with @samp{mmap} support.
