wasm-objdump

wasm-objdump is a command line tool used for inspecting and disassembling WebAssembly (Wasm) binary files. It is a part of the WebAssembly Binary Toolkit (wabt) project, which provides various tools for working with Wasm.

The main purpose of wasm-objdump is to analyze and present the low-level details of a Wasm binary file. It can display information such as the module header, section headers, function bodies, exports, imports, table elements, memory segments, and more.

The tool supports different output formats, including GNU asm-like syntax, Intel-like syntax, and raw instruction bytes. This allows developers to choose their preferred format for disassembled code.

wasm-objdump is particularly useful for understanding how a Wasm module is structured, inspecting the control flow of functions, and analyzing the behavior of imported and exported functions.

By default, the command line tool displays the disassembly of all functions in the Wasm binary file. However, it provides several options for filtering the output, such as specifying particular functions, function indices, sections, or ranges of code.

Developers can leverage the functionalities of wasm-objdump to gain insights into the Wasm binaries they are working with, debug potential issues or optimizations, or simply explore the inner workings of a Wasm module.

Being an open-source tool, wasm-objdump is actively maintained and updated alongside the wabt project. It is available for use on various platforms, including macOS, Linux, and Windows.
