Metallic

A try to build a C runtime library for WebAssembly

This name is from Gary Bernhardt "The Birth & Death of JavaScript", where a world of metal web applications is conceived. This library is aimed to be a building block of early metal applications, whose performance is near native.

To achieve this goal, this library is written from scratch, including math functions. The math functions, especially float ones, take advantage of modern architectures to achieve both speed and accuracy. Most of them produce faithfully rounded results (error < 1 ulp) in reasonable time.

Dependencies

Compiler requirements

Currently only clang meet these requirements.

• WebAssembly backend
• GCC-compatible builtins
• ILP32 or LP64 data model

Internal dependency

• dlmalloc - Doug Lea's malloc with other memory management routines
