+* Added --warn-execstack-objects to warn about executable stacks only when an
+ input object file requests one. Also added --error-execstack and
+ --error-rxw-segments options to convert warnings about executable stacks and
+ segments into errors.
+
+ Also added --enable-error-execstack=[yes|no] and
+ --enable-error-rwx-segments=[yes|no] configure options to set the default for
+ converting warnings into errors.
+
+* The ELF linker will now generate a warning message if the stack is made
+ executable. By default this warning is not issued if the user has
+ specifically requested an executable stack via the "-z execstack"
+ command line option, but the warning can be forced via the new
+ "--warn-execstack" option. Alternatively all warnings about creating
+ an executable stack can be suppressed via the "--no-warn-execstack"
+ option.
+
+ In addition the ELF linker will also warn if it creates a memory resident
+ segment with all three of the Read, Write and eXecute permissions set, or
+ if it creates a thread local data segment with the eXecute permission set.
+ These warnings can be disabled via --no-warn-rwx-segments option and
+ re-enabled via the --warn-rwx-segments option.
+
+ New configure options can also control these new features:
+
+ --enable-warn-execstack=no
+ will disable the warnings about creating an executable stack.
+
+ --enable-warn-execstack=yes
+ will make --warn-execstack enabled by default.
+
+ --enable-warn-rwx-segments=no
+ will make --no-warn-rwx-segments enabled by default.
+
+ --enable-default-execstack=no
+ will stop the creation of an executable stack simply because an input file
+ is missing a .note.GNU-stack section, even on architectures where this
+ behaviour is the default.
+
Changes in 2.35:
* X86 NaCl target support is removed.

+@itemx --warn-execstack-objects
+@itemx --no-warn-execstack
+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 the same section, but without the
+executable flag bit set. If an input file does not have a
+@var{.note.GNU-stack} section 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 crafted assembler files.
+
+@kindex --error-execstack
+@item --error-execstack
+@itemx --no-error-execstack
+If the linker is going to generate a warning message about an
+executable stack then the @option{--error-execstack} option will
+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
+behaviour of generating warning messages.
