Can WAMR work in a bare-metal environment (a physical machine without OS and other software)? about wasm-micro-runtime HOT 2 CLOSED

Hi, WAMR is supposed to be able to run in some resource limited environments, may be you can build WAMR with some features enabled or disabled:

• Use global heap: initialize a global byte buffer as a heap allocator and allocate memory from it, so as not to call system malloc/free - cmake -DWAMR_BUILD_GLOBAL_HEAP_POOL=1.
• Disable libcwasi: cmake -DWAMR_BUILD_LIBC_WASI=0, and even disable libc-builtin if needed: cmake -DWAMR_BUILD_LIBC_BUILTIN=0
• Disable some other features: cmake -DWAMR_DISABLE_WAKEUP_BLOCKING_OP=1 -DWAMR_DISABLE_HW_BOUND_CHECK=1 -DWAMR_DISABLE_WRITE_GS_BASE=1 -DWAMR_BUILD_QUICK_AOT_ENTRY=0

For the above options, please refer to: https://github.com/bytecodealliance/wasm-micro-runtime/blob/main/doc/build_wamr.md#wamr-vmcore-cmake-building-configurations

• Add a new platform and implement the vmcore APIs

Thanks a lot!
Let me have a try :)
