Description
Supplies the low-level ABI support library needed by the LLVM C++ standard library for WASI targets. It helps C++ WebAssembly programs handle runtime details such as exceptions, type support, and standard-library integration where supported.
This is a supporting development library rather than a tool users run directly. It is normally installed as part of a WASI C++ toolchain or pulled in when building C++ code for WebAssembly.
