This is a minor bugfix release, which to my knowledge contains nothing
of importance to us. However, there is one QoL change to our patches.
We no longer force `-fpic` in the compiler driver, and instead use the
`--enable-default-pie` configure option to generate position-independent
code suitable for executables. For building shared libraries, the
`-fpic` flag must be specified explicitly.
This is a mostly straight-forward rebase of our patches on top of
13.1.0. The spec files needed a change, as GCC no longer supports STABS
debug information, but we were building GCC with support for it.
Highlights of this release include static `operator()`, The Equality
Operator You Are Looking For and extended `constexpr` support.
This shouldn't cause any breaking changes, so a toolchain rebuild is not
required.
As per Hendiadyoin's request, math errno is disabled by default, which
should enable some extra compiler optimizations in LibGL and LibSoftGPU
code that uses math functions heavily.

This hash format offers faster symbol lookup than the System V hash.
We've been using it in all our shared libraries for a long time, but did
not have it enabled by default in our toolchain, so ports couldn't make
use of it.
Before this change, our dynamic linker's global constructor handler
relied on the GNU linker implicitly including the content of `.ctors`
section inside `.init_array`. The mold linker does not do this, so
global constructors would fail to be called in the mold-built userland.
There is no point in sticking to `.ctors`, as most other systems already
use the superior `.init_array` scheme. This commit changes the kernel
linker script to not discard this new section, and enables it by default
in our toolchain.
The `aarch64/t-aarch64` makefile fragment needs to be included for the
aarch64-specific parts of GCC to be built. Before 738e52da5, this was
done implicitly, but now it is not. This caused the following error when
building the toolchain: "aarch64-builtins.o: No such file or directory".
We may need entries with spaces in makeopts, installopts, and
configopts, and at that point we should also convert depends and
auth_opts to avoid confusion.
CMake specifies -arch arm64 for our toolchain. Unfortunately that's an
option GCC only understands when built for macOS. This causes the build
to fail.
I haven't been able to get CMake to not specify that option so this adds
a dummy option to GCC.
This makes stdlib.h and stdio.h functions available in the std
namespace for C++.
libstdc++v3's link tests can fail if you don't have an up-to-date
build directory, for example:
1. Have libc with missing _Exit symbol because you haven't done
a build since that was added.
2. Run toolchain rebuild. libstdc++v3's configure script will
realize that it can do link tests in general but will fail
later on when it tries to link a program that tests for _Exit.
Even though this is a toolchain patch this does not necessarily
require rebuilding the toolchain right away. This is only required
once we start using any of these new members in the std namespace,
e.g. for ports.
This updates the way we verify signatures for the gcc
port because we were previously downloading the keychain
from the mirror which defeats the point of doing signature
checks.
- Replaced /Root with
- Improved documentation.
- Removed a few typos.
- Replaced with
- Added brackets in some cases.
Most of the changes were reviewed and applied manually.
Our TLS implementation relies on the TLS model being "initial-exec".
We previously enforced this by adding the '-ftls-model=initial-exec'
flag in the root CmakeLists file, but that did not affect ports - So
now we put that flag in the gcc spec files.
Closes#5366
- Remove superfluous function overrides and use makeopts instead
- Remove superfluous installopts
- Use run rather than cd'ing manually
- Ensure empty line between functions
* Use ${version} instead of explicit version numbers in urls/filenames
* Move -L option to port script, as this is always good
* Fix some various other stuff
