The latter is problematic as it may be contained in the username (e.g.
email address-like) and thus the $SRC_ROOT path. This would cause an
invalid sed command to be created, breaking both of these scripts.

`-D` doesn't exist on macOS. Just call `mkdir -p` instead.
|
|
|
|
We just need to pass -disable-werror, otherwise Clang will complain a
lot.

macOS ventura no longer comes with makeinfo. binutils has already been
fixed - see https://github.com/SerenityOS/serenity/pull/15932
This patch does the same for GDB.

This is necessary to build on MacOS. As discussed in #15530, Serenity
no longer appears to build on MacOS Ventura. This attempts to fix that
by enforcing it at the command level.
|
|
Neither are we changing any of our documentation files, nor do we need
any of the documentation that is likely being built.
With macOS potentially removing makeinfo from the default Xcode lineup,
SerenityOS not being able to install it at all currently due to a lack
of perl, and it otherwise just being a dependency that has to be
installed to make the build system happy, lets just stub it out.
|
|
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 brings the behaviour in line with Clang, which already does this
since a few revisions.
|
|
This makes binutils compatible with `./package.sh dev`, so that we can
regenerate patches more easily, and neatly stack (temporary) patches on
top.

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.

We currently don't really populate most of the fields, but that can
wait :^)

This version comes with general fixes and, more importantly, introduces
support for the packed RELR relocation format.

This commit adds support for building the SerenityOS userland with the
new [mold linker].
This is not enabled by default yet; to link using mold, run the
`Toolchain/BuildMold.sh` script to build the latest release of mold, and
set the `ENABLE_MOLD_LINKER` CMake variable to ON. This option relies on
toolchain support that has been added just recently, so you might need
to rebuild your toolchain for mold to work.
[mold linker]: https://github.com/rui314/mold

The `-fuse-ld=mold` flag was only added in the not-yet-released GCC 12.
Cherry-picked from the following upstream commit:
https://gcc.gnu.org/git/?p=gcc.git;a=commit;h=ad964f7eaef9c03ce68a01cfdd7fde9d56524868

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.

Our build of LLVM's objcopy now supports the single missing feature
(--update-section) that previously forced us to use the one from GNU
Binutils. This means that there is no reason anymore to build Binutils
alongside LLVM's tools.

OpenBSD gzip does not have the -k flag to keep the original after
extraction. Work around this by copying the original gzip to the dest
and then extracting. A bit of a hack, but only needs to be done for the
first-time or rebuilds
OpenBSD provides crypt in libc, not libcrypt. Adjust if/else to check
for either and proceed accordingly
Remove outdated OpenBSD checks when building the toolchain

I used "git grep -FIn http://" to find all occurrences, and looked at
each one. If an occurrence was really just a link, and if a https
version exists, and if our Browser can access it at least as well as the
http version, then I changed the occurrence to https.
I'm happy to report that I didn't run into a single site where Browser
can't deal with the https version.

This contains all the bits and pieces necessary to build a Clang binary
that will correctly compile SerenityOS.
I had some trouble with getting LLVM building with a single command, so
for now, I decided to build each LLVM component in a separate command
invocation. In the future, we can also make the main llvm build step
architecture-independent, but that would come with extra work to make
library and include paths work.
The binutils build invocation and related boilerplate is duplicated
because we only use `objdump` from GNU binutils in the Clang toolchain,
so most features can be disabled.

This is no longer necessary now that the kernel doesn't use libsupc++
anymore.
|
|
Turns out we don't need that after all.
|
|
Rather than having the toolchain build fail half-way through we should
check whether the user has installed all the required tools and
libraries early on.
|
|
Previously the buildstep function would obscure error codes because
the return value of the function was the exit code for the sed command
which caused us to continue execution even though one of the build
steps had failed.
With set -o pipefail the return value of the buildstep function is
the real command's exit code.

This ensures inter-machine compatibility by not emitting any processor
specific instructions. This fixes the issue raised by the non AVX-512
supporting GitHub actions runners.
|
|
-march=native specializes the binaries for the CPU features available on
the CPU the binary is being compiled on. This matches the needs of the
Toolchain, as it's always built and used on that machine only.
This should be safe for the github actions VMs as well, as they all run
on a standard VM SKU in "the cloud".
I saw small but notable improvements in end-2-end build times in my
local testing. Each compilation unit is on average around a second
faster on my Intel(R) Core(TM) i7-8705G CPU @ 3.10GHz.

BuildIt.sh had a bunch of SC2086 errors, where we were not quoting
variables in variable expansions. The logic being:
Quoting variables prevents word splitting and glob expansion,
and prevents the script from breaking when input contains spaces,
line feeds, glob characters and such.
Reference: https://github.com/koalaman/shellcheck/wiki/SC2086
As bcoles noticed in #6772, shellcheck actually found a real bug here,
where the user's build directory included spaces.
Close: #6772

Make this stuff a bit easier to maintain by using the
root level variables to build up the Toolchain paths.
Also leave a note for future editors of BuildIt.sh to
give them warning about the other changes they'll need
to make.

This enables POSIX threads for GCC and makes the -pthread
argument available.

Previously debug symbols were produced and then stripped.

MacOS's sed doesn't support "\x1b" expansion unlike GNU sed, but we can
still use bash's $'\x1b' to expand it.
