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 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
|
||||
|
||||
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.
|
||||
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
|
||||
crafted assembler files.

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.
