* The 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.
* TYPE=<type> is now supported in an output section description to set the
section type value.

@ -2653,6 +2653,33 @@ Warn if any global constructors are used. This is only useful for a few
object file formats. For formats like COFF or ELF, the linker can not
detect the use of global constructors.
@kindex --warn-execstack
@cindex warnings, on exectuable stack
@cindex executable stack, warnings on
@item --warn-execstack
@itemx --no-warn-execstack
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} comman line options have been specified. This warning
can be disabled via the @command{--no-warn-execstack} option.
Note: ELF format input files 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.
@kindex --warn-multiple-gp
@item --warn-multiple-gp
Warn if multiple global pointer values are required in the output file.
