* Added doc comments for `std.Target.ObjectFormat` enum
* `std.Target.oFileExt` is removed because it is incorrect for Plan-9
targets. Instead, use `std.Target.ObjectFormat.fileExt` and pass a
CPU architecture.
* Added `Compilation.Directory.joinZ` for when a null byte is desired.
* Improvements to `Compilation.create` logic for computing `use_llvm`
and reporting errors in contradictory flags. `-femit-llvm-ir` and
`-femit-llvm-bc` will now imply `-fLLVM`.
* Fix compilation when passing `.bc` files on the command line.
* Improvements to the stage2 LLVM backend:
- cleaned up error messages and error reporting. Properly bubble up
some errors rather than dumping to stderr; others turn into panics.
- properly call ZigLLVMCreateTargetMachine and
ZigLLVMTargetMachineEmitToFile and implement calculation of the
respective parameters (cpu features, code model, abi name, lto,
tsan, etc).
- LLVM module verification only runs in debug builds of the compiler
- use LLVMDumpModule rather than printToString because in the case
that we incorrectly pass a null pointer to LLVM it may crash during
dumping the module and having it partially printed is helpful in
this case.
- support -femit-asm, -fno-emit-bin, -femit-llvm-ir, -femit-llvm-bc
- Support LLVM backend when used with Mach-O and WASM linkers.
A general-purpose programming language and toolchain for maintaining robust, optimal, and reusable software.

License
The ultimate goal of the Zig project is to serve users. As a first-order effect, this means users of the compiler, helping programmers to write better software. Even more important, however, are the end-users.
Zig is intended to be used to help end-users accomplish their goals. Zig should be used to empower end-users, never to exploit them financially, or to limit their freedom to interact with hardware or software in any way.
However, such problems are best solved with social norms, not with software licenses. Any attempt to complicate the software license of Zig would risk compromising the value Zig provides.
Therefore, Zig is available under the MIT (Expat) License, and comes with a humble request: use it to make software better serve the needs of end-users.
This project redistributes code from other projects, some of which have other licenses besides MIT. Such licenses are generally similar to the MIT license for practical purposes. See the subdirectories and files inside lib/ for more details.
