Changes in 2.36:
* Add libdep plugin, for linking dependencies of static libraries that
were recorded by ar in the __.LIBDEP archive member.
* Add --error-handling-script=<NAME> command line option to allow a helper
script to be invoked when an undefined symbol or a missing library is
encountered. This option can be suppressed via the configure time
switch: --enable-error-handling-script=no.
* Add -z lam-u48 to x86-64 ELF linker to generate LAM_U48 property.
* Add -z lam-u57 to x86-64 ELF linker to enerate LAM_U57 property.
* Add -z lam-u48-report=[none|warning|error] to report missing LAM_U48
property.
* Add -z lam-u57-report=[none|warning|error] to report missing LAM_U57
property.
* Add -z lam-report=[none|warning|error] to report missing LAM_U48 and
LAM_U57 properties.
* Add -z x86-64-{baseline|v[234]} to the x86 ELF linker to mark
x86-64-{baseline|v[234]} ISA level as needed.
* Add -z unique-symbol to avoid duplicated local symbol names.
* The creation of PE format DLLs now defaults to using a more secure set
of DLL
characteristics.
* The linker now deduplicates the types in .ctf sections. The new
command-line option --ctf-share-types describes how to do this:
its default value, share-unconflicted, produces the most compact
output.
* The linker now omits the "variable section" from .ctf sections by
default, saving space. This is almost certainly what you want
unless you are working on a project that has its own analogue
of symbol tables that are not reflected in the ELF symtabs.
* Add support for the SHF_GNU_RETAIN ELF section flag.
This flag specifies that the section should not be garbage collected by
the
linker.
