sin-ack 910bff9e94 Ports: Update the Zig port's Serenity type definitions After `b98f537`, the Zig port's types for Serenity no longer matched what Serenity actually returned from LibC; this caused weird errors due to stat() not returning valid values anymore.		2023-06-04 05:39:32 +02:00

Patches for zig on SerenityOS

`0001-Add-support-for-building-LLVM-on-SerenityOS.patch`

Add support for building LLVM on SerenityOS

Adds SerenityOS #ifdefs for platform-specific code.

We stub out wait4, as SerenityOS doesn't support querying a child process's resource usage information.

`0002-Add-triple-for-SerenityOS.patch`

Add triple for SerenityOS

`0003-Add-support-for-SerenityOS.patch`

Add support for SerenityOS

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.

`0004-Default-to-ftls-model-initial-exec-on-SerenityOS.patch`

Default to -ftls-model=initial-exec on SerenityOS

This is a hack to make Clang use the initial-exec TLS model instead of the default local-exec when building code for Serenity.

This patch should be removed when we implement proper TLS support.

`0005-Add-support-for-SerenityOS.patch`

Add support for SerenityOS

This commit teaches libc++ about what features are available in our LibC, namely:

We do not have locale support, so no-op shims should be used in place of the C locale API.
The number of errno constants defined by us is given by the value of the ELAST macro.
Multithreading is implemented though the pthread library.
Use libc++'s builtin character type table instead of the one provided by LibC as there's a lot of extra porting work to convince the rest of locale.cpp to use our character type table properly.

This commit is an adaptation of the LLVM patch by Daniel Bertalan to fit the layout of the zig-bootstrap project.

`0006-Allow-undefined-symbols-on-SerenityOS.patch`

Allow undefined symbols on SerenityOS

Allow undefined symbols in LLVM libraries, which is needed because only stubs are available for SerenityOS libraries when libc++ and libunwind are built.

`0007-Support-building-shared-libLLVM-and-libClang-for-Ser.patch`

Support building shared libLLVM and libClang for SerenityOS

This patch tells CMake that the --whole-archive linker option should be used for specifying the archives whose members will constitute these shared libraries.

Symbol versioning is disabled, as the SerenityOS loader doesn't support it, and the ELF sections that store version data would just waste space.

`0008-Add-SerenityOS-to-config.guess.patch`

Add SerenityOS to config.guess

`0009-Prevent-the-use-of-POSIX-shm-on-SerenityOS.patch`

Prevent the use of POSIX shm on SerenityOS

POSIX shm is not supported by SerenityOS yet, so this causes a compilation error.

`0010-llvm-Implement-bigint-to-LLVM-int-for-32-bit-compile.patch`

llvm: Implement bigint-to-LLVM int for 32-bit compiler builds

The conversion to DoubleLimb is necessary due to LLVM only accepting 64-bit limbs for big integers. Since we need some space to store it, we also have to allocate. This is an unfortunate penalty that 32-bit compiler builds have to take.

`0011-Add-SerenityOS-target.patch`

Add SerenityOS target

Named "serenity" within the code to match what LLVM says.

`0012-Implement-SerenityOS-support-in-std.patch`

Implement SerenityOS support in std

`0013-build-Adjust-build-process-for-SerenityOS.patch`

build: Adjust build process for SerenityOS
