Total bytes used in stage1 std lib tests: 3.418 -> 3.198 GiB (saving 225 MiB) There's still this from pass 1 not getting freed: Const: 6909049 items, 72 bytes each, total 474.407 MiB This is due to 2 things hanging on to references to IrAnalyze pointers: * ZigVar->owner_exec->analysis * LazyValue->ira The LazyValue one could be solved by memoizing the results after the lazy value is resolved, and then it could unref the IrAnalyze. ZigVars that are determined to be comptime const, could have their const_value set to that value, instead of using the mem_slot_index mechanism. This would prevent an IrAnalyze ref in some cases.

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 == 9.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 == 9.x
- Use the pre-built binaries or build from source.
Instructions
POSIX
mkdir build
cd build
cmake ..
make install
MacOS
brew install cmake llvm@9
brew outdated llvm@9 || brew upgrade llvm@9
mkdir build
cd build
cmake .. -DCMAKE_PREFIX_PATH=$(brew --prefix llvm)
make install
Windows

Stage 2: Build Self-Hosted Zig from Zig Source Code
Note: Stage 2 compiler is not complete. Beta users of Zig should use the Stage 1 compiler for now.
Dependencies are the same as Stage 1, except now you can use stage 1 to compile Zig code.
bin/zig build --prefix $(pwd)/stage2
This produces ./stage2/bin/zig which can be used for testing and development.
Once it is feature complete, it will be used to build stage 3 - the final compiler
binary.
Stage 3: Rebuild Self-Hosted Zig Using the Self-Hosted Compiler
Note: Stage 2 compiler is not yet able to build Stage 3. Building Stage 3 is not yet supported.
Once the self-hosted compiler can build itself, this will be the actual compiler binary that we will install to the system. Until then, users should use stage 1.
Debug / Development Build
./stage2/bin/zig build --prefix $(pwd)/stage3
Release / Install Build
./stage2/bin/zig build install -Drelease
