Daniel Bertalan e88ca09609 Ports: Upgrade LLVM to version 13.0.0 
With this update, we now use our custom `serenity` Clang target, which
means that all system-specific compilation options (e.g. default PIE,
header search paths) will be handled automatically.

This port has been tested to build `Source/little` on all 4
toolchain-architecture pairs. Furthermore, `lib(std)c++` headers are
picked up correctly and our AK headers can be included without any
issues.

Due to recent kernel fixes related to memory-mapped files, the LLD
linker can now be used by default, so there's no need to also build the
GCC port alongside this.

Although our patches cover building libLLVM as a shared library, this is
currently not enabled by default, as DynamicLoader is very slow in
dealing with such a large number of relocations.

Patches for LLVM on SerenityOS

build-crt.patch

This patch lets us use LLVM's crtbegin.o/crtend.o implementation.

Status

  • Local?
  • Should be merged to upstream?
  • Resolves issue(s) with our side of things
  • Hack

insert-ifdef-serenity.patch

This patch adds several defines in order to omit things not supported by SerenityOS.

Status

  • Local?
  • Should be merged to upstream?
  • Resolves issue(s) with our side of things
  • Hack

remove-version-script.patch

Instructs the linker to not build LLVM shared libraries (libclang.so, libLTO.so, etc.) with symbol versioning, which our dynamic linker does not support.

Status

  • Local?
  • Should be merged to upstream?
  • Resolves issue(s) with our side of things
  • Hack

remove-wstring.patch

Removes std::wstrings from the source code, as our libstdc++ does not support it.

Status

  • Local?
  • Should be merged to upstream?
  • Resolves issue(s) with our side of things
  • Hack

toolchain.patch

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 building position-independent executables by default.
