Nix (nixpkgs) have updated a while back how the e2fsprogs derivation
works and now fuse2fs wasnt being installed with it. It is now needed to
add a new derivation (package) to the dependency list: "fuse2fs". This
fixes the Meta/serenity.sh script not finding the fuse2fs binary for
rootless image building :^)
This is a preparation to check if our users find noticeable bugs in the
x86-64 target, before we can decide if we want to remove the i686 target
for good.
This keeps us from accidentally building toolchains that don't make it
through a clean build if we build them using a populated sysroot, as it
would otherwise detect libpthread and friends and try to pull them in
while LibC is not yet built.
Following the pattern for qemu, mold, and clang, we should install the
host ruby required to build the ruby port into its own install tree
rather than forcing it into the GNU compiler's bindir.
Following the pattern for qemu, mold, and clang, we should install the
host python required to build the python port into its own install tree
rather than forcing it into the GNU compiler's bindir.
Now that the lower pages can be unmapped and more of the virtual
address range is available to us, we can actually use the default
mapping address of x86_64 again.
This reverts commit 292398b585.
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 release brings support for various C++23 constructs like `if
consteval` and multidimensional subscript operators. Vectorization is
now enabled for O2 too, and `-ftrivial-auto-var-init` has been added
which can help us find and prevent security issues coming from
uninitialized variables.
Toolchain/Patches/gcc.patch is now significanly smaller as some unused,
autoconf-generated code has been removed.
Add a patch to let llvm's InstrProfiling modules know serenity supports
all the Unix-y features required to make -fprofile-instr-generate and
-fcoverage-mapping work properly on target.
Besides a version bump, the following changes have been made to our
toolchain infrastructure:
- LLVM/Clang is now built with -march=native if the host compiler
supports it. An exception to this is CI, as the toolchain cache is
shared among many different machines there.
- The LLVM tarball is not re-extracted if the hash of the applied
patches doesn't differ.
- The patches have been split up into atomic chunks.
- Port-specific patches have been integrated into the main patches,
which will aid in the work towards self-hosting.
- <sysroot>/usr/local/lib is now appended to the linker's search path by
default.
- --pack-dyn-relocs=relr is appended to the linker command line by
default, meaning ports take advantage of RELR relocations without any
patches or additional compiler flags.
The formatting of LLVM port's package.sh has been bothering me, so I
also indented the arguments to the CMake invocation.
* x11 package name has changed to xlibsWrapper.
* texinfo is necessary for Makeinfo.
* e2fsprogs was recenty fixed on nicpkgs to include fuse2fs to mount
serenity images without root access but it needed some configuration.
Moves the nix script to setup the build environment from Documentation
into the Toolchain as a callable script. I also modified the script
to accept a "pkgs" argument to make it easy to override the nixpkgs
version from the command-line when calling the script.
