-On ELF platforms this option controls how the linker generates warning
-messages when it creates an output file with an executable stack. By
-default the linker will not warn if the @command{-z execstack} command
-line option has been used, but this behaviour can be overridden by the
-@option{--warn-execstack} option.
-
-On the other hand the linker will normally warn if the stack is made
-executable because one or more of the input files need an execuable
-stack and neither of the @command{-z execstack} or @command{-z
-noexecstack} command line options have been specified. This warning
-can be disabled via the @command{--no-warn-execstack} option.

+On ELF platforms the linker may generate warning messages if it is
+asked to create an output file that contains an executable stack.
+There are three possible states:
+@enumerate
+@item
+Do not generate any warnings.
+@item
+Always generate warnings, even if the executable stack is requested
+via the @option{-z execstack} command line option.
+@item
+Only generate a warning if an object file requests an executable
+stack, but not if the @option{-z execstack} option is used.
+@end enumerate
+
+The default state depends upon how the linker was configured when it
+was built. The @option{--no-warn-execstack} option always puts the
+linker into the no-warnings state. The @option{--warn-execstack}
+option puts the linker into the warn-always state. The
+@option{--warn-execstack-objects} option puts the linker into the
+warn-for-object-files-only state.
+
+Note: ELF format input files can specify that they need an executable
stack by having a @var{.note.GNU-stack} section with the executable
bit set in its section flags. They can specify that they do not need
-an executable stack by having that section, but without the executable
-flag bit set. If an input file does not have a @var{.note.GNU-stack}
-section present then the default behaviour is target specific. For
-some targets, then absence of such a section implies that an
-executable stack @emph{is} required. This is often a problem for hand

+If the linker is going to generate a warning message about an

+instead change that warning into an error. Note - this option does
+not change the linker's execstack warning generation state. Use
+@option{--warn-execstack} or @option{--warn-execstack-objects} to set
+a specific warning state.
+
+The @option{--no-error-execstack} option will restore the default
