+* arm-symbianelf support removed.
+
+* Add -z report-relative-reloc to x86 ELF linker to report dynamic
+ relative relocations.
+
+* Add -z start-stop-gc to disable special treatment of __start_*/__stop_*
+ references when --gc-sections.
+
+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.
+
+Changes in 2.35:
+
+* X86 NaCl target support is removed.
+
+* Add ELF linker command-line options, --export-dynamic-symbol and
+ --export-dynamic-symbol-list, to make symbols dynamic.
+
+* Add a configure option, --enable-textrel-check=[no|yes|warning|error],
+ to decide what ELF linker should do by default with DT_TEXTREL in an
+ executable or shared library. Default to yes for Linux/x86 targets.
+
+* The -Map=<filename> command line option has been extended so that if
+ <filename> is a directory then <filename>/<output-filename>.map will be
+ created.
+
+* Add a command-line option for ELF linker, --warn-textrel, to warn that
+ DT_TEXTREL is set in a position-independent executable or shared object.
+
+* Add command-line options --enable-non-contiguous-regions and
+ --enable-non-contiguous-regions-warnings.
+
+* Add command-line option --imagic for the pdp11-aout target to output format
+ IMAGIC (0411) for separate instruction and data spaces, and change the
+ default format option for pdp11-aout to be --omagic.
+
+* Relative pathnames in INPUT() and GROUP() directives in linker scripts are
+ searched relative to the directory of the linker script before other search
+ paths.
+
+* Add ELF linker command-line option `-z start-stop-visibility=...' to control
+ the visibility of synthetic `__start_SECNAME` and `__stop_SECNAME` symbols.
+
+* Add command-line option --dependency-file to write a Make-style dependency
+ file listing the input files consulted by the linker, like the files written
+ by the compiler's -M -MP options.
+
+Changes in 2.34:
+
+* The ld check for "PHDR segment not covered by LOAD segment" is more
+ effective, catching cases that were wrongly allowed by previous versions of
+ ld. If you see this error it is likely you are linking with a bad linker
+ script or the binary you are building is not intended to be loaded by a
+ dynamic loader. In the latter case --no-dynamic-linker is appropriate.
+
+* cr16c support removed.
+
+* Add support for z80-elf.
+
+* Add support for relocation of each byte or word of multibyte value to Z80
+ targets.
+
+* Add support for Zilog eZ80 (both ADL and Z80 mode) and Zilog Z180 CPUs.
+
Changes in 2.33:
+* Add command-line option --no-print-map-discarded.
+
+* The Cortex-A53 Erratum 843419 workaround now supports a choice of which
+ workaround to use. The option --fix-cortex-a53-843419 now takes an
+ optional argument --fix-cortex-a53-843419[=full|adr|adrp] which can be
+ used to force a particular workaround to be used. See --help for AArch64
+ for more details.
+
* Add target handlers for AArch64 for ELF GNU program properties.
* Add support for GNU_PROPERTY_AARCH64_FEATURE_1_BTI in ELF GNU program
* Add support for GNU_PROPERTY_AARCH64_FEATURE_1_PAC in ELF GNU program
properties in the AArch64 ELF linker.
-* Add --force-bti for AArch64 to enable GNU_PROPERTY_AARCH64_FEATURE_1_BTI
+* Add -z force-bti for AArch64 to enable GNU_PROPERTY_AARCH64_FEATURE_1_BTI
on output while warning about missing GNU_PROPERTY_AARCH64_FEATURE_1_BTI
on inputs and use PLTs protected with BTI.
-* Add --pac-plt for AArch64 to pick PAC enabled PLTs.
+* Add -z pac-plt for AArch64 to pick PAC enabled PLTs.
Changes in 2.32:
other utilities should work on Risc/Ultrix and Irix.
