This makes sense from an organizational point of view, as explained by this new doc comment at the top of the new file: //! Semantic analysis of ZIR instructions. //! This file operates on a `Module` instance, transforming untyped ZIR //! instructions into semantically-analyzed IR instructions. It does type //! checking, comptime control flow, and safety-check generation. This is the //! the heart of the Zig compiler. //! When deciding if something goes into this file or into Module, here is a //! guiding principle: if it has to do with (untyped) ZIR instructions, it goes //! here. If the analysis operates on typed IR instructions, it goes in Module. Before: 4009 src-self-hosted/Module.zig After: 2776 src-self-hosted/Module.zig 1128 src-self-hosted/zir_sema.zig This should be sufficient to avoid the situation we have in stage1 where ir.cpp is 32,516 lines.

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brew outdated llvm || brew upgrade llvm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
or
error: unable to create target: 'Unable to find target for this triple (no targets are registered)',
in which case try -DZIG_WORKAROUND_4799=ON
Hopefully this will be fixed upstream with LLVM 10.0.1.
Windows
