chao an 4f11f38c38 interpreters/wamr: add compile role of WebAssembly
Add compilation rules to support WebAssembly(WASM/WAMR):

1. Compile Toolchain
 1> Download WASI sdk and export the WASI_SDK_PATH path:

$ wget https://github.com/WebAssembly/wasi-sdk/releases/download/wasi-sdk-19/wasi-sdk-19.0-linux.tar.gz
$ tar xf wasi-sdk-19.0-linux.tar.gz
Put wasi-sdk-19.0 to your host WASI_SDK_PATH environment variable, like:
$ export WASI_SDK_PATH=`pwd`/wasi-sdk-19.0

 2> Download Wamr "wamrc" AOT compiler and export to the PATH:
$ mkdir wamrc
$ wget https://github.com/bytecodealliance/wasm-micro-runtime/releases/download/WAMR-1.1.2/wamrc-1.1.2-x86_64-ubuntu-20.04.tar.gz
$ tar xf wamrc-1.1.2-x86_64-ubuntu-20.04.tar.gz
$ export PATH=$PATH:$PWD

2. Configuring and running

 1> Configuring sim/wamr and compile:

nuttx$ ./tools/configure.sh  sim/wamr
nuttx$ make
...
Wamrc Generate AoT: /home/archer/code/nuttx/n5/apps/wasm/hello.aot
Wamrc Generate AoT: /home/archer/code/nuttx/n5/apps/wasm/coremark.aot
LD:  nuttx

 2> Copy the generated wasm file(Interpreter/AoT)

nuttx$ cp ../apps/wasm/hello.aot .
nuttx$ cp ../apps/wasm/hello.wasm .
nuttx$ cp ../apps/wasm/coremark.wasm .

 3> Run iwasm

nuttx$ ./nuttx
NuttShell (NSH) NuttX-10.4.0
nsh> iwasm /data/hello.wasm
Hello, World!!
nsh> iwasm /data/hello.aot
Hello, World!!
nsh> iwasm /data/coremark.wasm

Interpreters

This apps/ directory is set aside to hold interpreters that may be incorporated into NuttX.

Ficl

This is DIY port of Ficl (the Forth Inspired Command Language). See http://ficl.sourceforge.net/. It is a DIY port because the Ficl source is not in that directory, only an environment and instructions that will let you build Ficl under NuttX. The rest is up to you.

Lua

Fetch and build a Lua interpreter. Versions 5.2 through 5.4 are supported. The lua command will be added to NSH. Lua can run a script for a given path, execute a string of code, or open a readline compatible REPL on the NSH console. The <lua.h> and <lauxlib.h> headers are available to start a new embedded interpreter or extend Lua with C modules. See the luamod_hello example for how to include a built-in module.

A math library is required to build. Enable the LIBM config or use a toolchain provided math library.

The following configs are recommended for a full featured Lua interpreter:

  • LIBC_FLOATINGPOINT
  • SYSTEM_READLINE
