//================
// Binaryen C API
//
// The first part of the API lets you create modules and their parts.
//
// The second part of the API lets you perform operations on modules.
//
// The third part of the API lets you provide a general control-flow
//   graph (CFG) as input.
//
// The final part of the API contains miscellaneous utilities like
//   debugging for the API itself.
//
// ---------------
//
// Thread safety: You can create Expressions in parallel, as they do not
//                refer to global state. BinaryenAddFunction is also
//                thread-safe, which means that you can create functions and
//                their contents in multiple threads. This is important since
//                functions are where the majority of the work is done.
//                Other methods - creating imports, exports, etc. - are
//                not currently thread-safe (as there is typically no need
//                to parallelize them).

// ========== CFG / Relooper ==========
//
// General usage is (1) create a relooper, (2) create blocks, (3) add
// branches between them, (4) render the output.
//
// For more details, see src/cfg/Relooper.h and
// https://github.com/WebAssembly/binaryen/wiki/Compiling-to-WebAssembly-with-Binaryen#cfg-api
