Fix nightly-run CI and CodeQL CI (#3250) 
- Fix nightly run CI failure which was introduced by PR #3239 and now it must set
  WAMR_BUILD_TARGET when building iwasm for Android platform
- Remove building llvm, wamrc and jit in CodeQL CI, since it will
  do static code analyzing for llvm project and cause CodeQL run
  failed: `Oops! A fatal internal error occurred.
  This particular kind of error most often happens as a side effect of running out of
  disk space.`

Build WAMR | Build AOT Compiler | Embed WAMR | Export Native API | Build Wasm Apps | Samples

WebAssembly Micro Runtime (WAMR) is a lightweight standalone WebAssembly (Wasm) runtime with small footprint, high performance and highly configurable features for applications cross from embedded, IoT, edge to Trusted Execution Environment (TEE), smart contract, cloud native and so on. It includes a few parts as below:

  • VMcore: A set of runtime libraries for loading and running Wasm modules. It supports several execution modes including interpreter, Ahead-of-Time compilation(AoT) and Just-in-Time compilation (JIT). The WAMR supports two JIT tiers - Fast JIT, LLVM JIT, and dynamic tier-up from Fast JIT to LLVM JIT.
  • iwasm: The executable binary built with WAMR VMcore supports WASI and command line interface.
  • wamrc: The AOT compiler to compile Wasm file into AOT file
  • Useful components and tools for building real solutions with WAMR vmcore:
    • App-framework: A framework for supporting APIs for the Wasm applications
    • App-manager: a framework for dynamical loading the Wasm module remotely
    • WAMR-IDE: An experimental VSCode extension for developping WebAssembly applications with C/C++

Key features

Wasm post-MVP features

Supported architectures and platforms

The WAMR VMcore supports the following architectures:

  • X86-64, X86-32
  • ARM, THUMB (ARMV7 Cortex-M7 and Cortex-A15 are tested)
  • AArch64 (Cortex-A57 and Cortex-A53 are tested)
  • RISCV64, RISCV32 (RISC-V LP64 and RISC-V LP64D are tested)
  • XTENSA, MIPS, ARC

The following platforms are supported, click each link below for how to build iwasm on that platform. Refer to WAMR porting guide for how to port WAMR to a new platform.
