The indexes are stored separately using an array of uint8_t, uint16_t, uint32_t, or size_t, depending on the number of entries in the map. Entries only contain a key and a value, no longer have distance_from_start_index or is_used. In theory this should be both faster and use less memory. In practice it seems to have little to no effect. For the standard library tests, vs master branch, the time had no discernable difference, and it shaved off only 13 MiB of peak rss usage.
A general-purpose programming language and toolchain for maintaining robust, optimal, and reusable software.

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
Need help? Troubleshooting Build Issues
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brew outdated llvm || brew upgrade llvm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
