Wasp is a C++ library designed to make it easy to work with WebAssembly modules. Unlike tools like wabt, it is designed to be used as a library.
It also includes the wasp tool, which has the following commands:
wasp dump: Dump the contents of a WebAssembly modulewasp callgraph: Generate a dot graph of the module's callgraphwasp cfg: Generate a dot graph of a function's control-flow graphwasp dfg: Generate a dot graph of a function's data-flow graph
Disassemble all functions in a module:
$ wasp dump -d mod.wasmDisplay all sections in a module:
$ wasp dump -h mod.wasmDisplay the contents of the "import" section:
$ wasp dump -j import -x mod.wasmWrite the callgraph as a DOT file to stdout.
$ wasp callgraph mod.wasmWrite the callgraph as a DOT file to file.dot.
$ wasp callgraph mod.wasm -o file.dotWrite the CFG of function 0 as a DOT file to stdout.
$ wasp cfg -f 0 mod.wasmWrite the CFG of function foo as a DOT file to file.dot.
$ wasp cfg -f foo mod.wasm -o file.dotWrite the DFG of function 0 as a DOT file to stdout.
$ wasp dfg -f 0 mod.wasmWrite the DFG of function foo as a DOT file to file.dot.
$ wasp dfg -f foo mod.wasm -o file.dot
