New features:
* Functions can have parameters in semantic analysis. Codegen
is not implemented yet.
* Support for i8, i16, i32, i64, u8, u16, u32, u64 primitive
identifiers.
* New ZIR instructions: arg, block, and breakvoid
Implementation details:
* Move Module.Body to ir.Body
* Scope.Block gains a parent field and an optional Label field
* Fix bug in integer type equality comparison.
Here's the test case I'm working towards:
```
@void = primitive(void)
@i32 = primitive(i32)
@fnty = fntype([@i32, @i32], @void)
@0 = str("entry")
@1 = export(@0, "entry")
@entry = fn(@fnty, {
%0 = arg(0)
%1 = arg(1)
%2 = add(%0, %1)
%3 = int(7)
%4 = block("if", {
%neq = cmp(%2, neq, %3)
%5 = condbr(%neq, {
%6 = unreachable()
}, {
%7 = breakvoid("if")
})
})
%11 = returnvoid()
})
```
$ ./zig-cache/bin/zig build-obj test.zir
test.zir:9:12: error: TODO implement function parameters for Arch.x86_64
That's where I left off.

Building from Source
Note that you can download a binary of master branch.
Stage 1: Build Zig from C++ Source Code
Dependencies
POSIX
- cmake >= 2.8.5
- gcc >= 5.0.0 or clang >= 3.6.0
- LLVM, Clang, LLD development libraries == 10.x, compiled with the same gcc or clang version above
- Use the system package manager, or build from source.
Windows
- cmake >= 3.15.3
- Microsoft Visual Studio. Supported versions:
- 2015 (version 14)
- 2017 (version 15.8)
- 2019 (version 16)
- LLVM, Clang, LLD development libraries == 10.x
- Use the pre-built binaries or build from source.
Instructions
POSIX
mkdir build
cd build
cmake ..
make install
MacOS
brew install cmake llvm
brew outdated llvm || brew upgrade llvm
mkdir build
cd build
cmake .. -DCMAKE_PREFIX_PATH=$(brew --prefix llvm)
make install
You will now run into this issue: homebrew and llvm 10 packages in apt.llvm.org are broken with undefined reference to getPollyPluginInfo
Please help upstream LLVM and Homebrew solve this issue, there is nothing Zig can do about it. See that issue for a workaround you can do in the meantime.
Windows
See https://github.com/ziglang/zig/wiki/Building-Zig-on-Windows
