serenity/Toolchain/Patches/llvm/0001-clang-Add-support-for-SerenityOS.patch
Dan Klishch fa1eef8bbe Toolchain: Update LLVM to 18.1.3 
Apart from bumping the toolchain Clang's and port's version, this commit
completely overhauls the way LLVM toolchain is built.

First, it gets rid of a complicated two-stage process of first compiling
clang and compiler-rt builtins and then building libunwind, libc++abi,
and libc++ -- it is possible to create a complete cross-compilation
toolchain in a single CMake invocation with a modern LLVM. Moreover, the
old method was inherently unsupported and subtly broken.

Next, it utilizes full potential of the Stubs "framework". Now we are
even able to compile Clang with -Wl,-z,defs which makes one of the
patches obsolete and the whole installation less error-prone. Note that
it comes at a cost of complicating the bootstrap process on a completely
novel architecture but this hopefully won't happen often.

Lastly, it fixes handling of the -no*lib* family of flags in the
Serenity LLVM driver and correctly uses -nostartfiles in conjunction
with stubs to make necessary CMake configure-time checks succeed.

Subject: [PATCH] [clang] Add support for SerenityOS
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Adds support for the `$arch-pc-serenity` target to the Clang front end.
This makes the compiler look for libraries and headers in the right
places, and enables some security mitigations like stack-smashing
protection and position-independent code by default.
