Changelog:
General Improvements
Fixed LTO link-time performance problems caused by an overflow in the
partitioning algorithm while building large binaries.
Language Specific Changes
C++
GCC 8.2 fixed a bug introduced in GCC 8.1 affecting passing or returning of
classes with a deleted copy constructor and defaulted trivial move constructor
(bug c++/86094). GCC 8.2 introduces -fabi-version=13 and makes it the default,
ABI incompatibilities between GCC 8.1 and 8.2 can be reported with -Wabi=12.
See C++ changes for more details.
Target Specific Changes
IA-32/x86-64
-mtune=native performance regression PR84413 on Intel Skylake processors
has been fixed.
Changelog:
2.31.1
This release also contains a fix for gold/23409 where the gold
linker could end up creating duplicate copies of some symbols.
2.31
This release contains numerous bug fixes, and also the
following new features:
* Direct linking with DLLs for Cygwin and Mingw targets is now faster.
* The linker now defaults to enabling -z separate-code for Linux
targets, although a configure time option can change this.
This option can increase disk and memory size of executables, but
it does help to improve security.
* The disassembler supports Netronome Flow Processor (NFP) firmware
files.
* The AArch64 disassembler supports showing disassembly notes which
are emitted when inconsistencies are found with the instruction that
may result in the instruction being invalid. It also emits warnings
when a combination of an instruction and a named register could be
invalid.
* The AR archive manager now supports an "O" modifier to display
member offsets inside an archive.
* The ADR and ADRL pseudo-instructions supported by the ARM assembler
now only set the bottom bit of the address of thumb function symbols
if the -mthumb-interwork command line option is active.
* The MIPS assembler supports the Global INValidate (GINV) and
Cyclic Redudancy Check (CRC) architecture extensions.
* Support has been added for the Freescale S12Z architecture.
* The assembler has a new --generate-missing-build-notes=[yes|no]
option to create (or not) GNU Build Attribute notes if none are
present in the input sources.
* The -mold-gcc command-line option has been removed for x86 targets.
* The x86 assembler now supports a -O[2|s] command-line options to
enable alternate shorter instruction encodings.
* The gold linker has a new --debug=plugin option for easier debugging
of plugin-related problems.
* The gold linker now supports the -z keep_text_section_prefix option.
* The gold linker now has support for .note.gnu.property sections
(from Linux ABI extensions).
* Add gold linker now has support for Intel's Indirect Branch Tracking
(IBT) and Shadow Stack instructions.

This release contains numerous bug fixes, and also the
following new features:
In the assembler:
* Add support for location views in DWARF debug line information.
In the BFD linker:
* Add -z separate-code to generate separate code PT_LOAD segment.
* Add "-z undefs" command line option as the inverse of the "-z defs" option.
* Add -z globalaudit command line option to force audit libraries to be run
for every dynamic object loaded by an executable - provided that the loader
supports this functionality.
* Tighten linker script grammar around file name
specifiers to prevent the use of SORT_BY_ALIGNMENT and
SORT_BY_INIT_PRIORITY on filenames. These would
previously be accepted but had no effect.
* The EXCLUDE_FILE directive can now be placed within any
SORT_* directive within input section lists.
In the GOLD linker:
* Add support for .MIPS.options sections (MIPS only).
* Add support for compound relocations (MIPS only).
* Add --emit-stub-syms, --no-tls-optimize, --tls-get-addr-optimize
options (PowerPC only).
* Add -z text-unlikely-segment option.
* Add plugin support for adding new input files
(LDPT_REGISTER_NEW_INPUT_HOOK).
In the utilities:
* Add --debug-dump=links option to readelf and
--dwarf=links option to objdump which displays the
contents of any .gnu_debuglink or .gnu_debugaltlink
sections.
* Add a --debug-dump=follow-links option to readelf and a
--dwarf=follow-links option to objdump which causes indirect
links into separate debug info files to be followed when
dumping other DWARF sections.
Performing substitutions during post-patch breaks tools such as mkpatches,
making it very difficult to regenerate correct patches after making changes,
and often leading to substituted string replacements being committed.

This switch is meant to be used by packages requiring an implementation of the
former libusb (as in devel/libusb). The original implementation can be
chosen by setting LIBUSB_TYPE to "native".
The alternative implementation libusb-compat (as in devel/libusb-compat) wraps
libusb1 (in devel/libusb1). This implementation can be chosen by setting
LIBUSB_TYPE to "compat". On NetBSD, it has the advantage of not requiring root
privileges to locate and use USB devices without a kernel driver.
This second part switches packages using libusb to this framework. It does not
change compilation options or dependencies at this point.
Compile-tested on most packages affected and available on NetBSD/amd64.
