Propose two enhancements: - Shared heap created from preallocated memory buffer: The user can create a shared heap from a pre-allocated buffer and see that memory region as one large chunk; there's no need to dynamically manage it(malloc/free). The user needs to make sure the native address and size of that memory region are valid. - Introduce shared heap chain: The user can create a shared heap chain, from the wasm app point of view, it's still a continuous memory region in wasm app's point of view while in the native it can consist of multiple shared heaps (each of which is a continuous memory region). For example, one 500MB shared heap 1 and one 500 MB shared heap 2 form a chain, in Wasm's point of view, it's one 1GB shared heap. After these enhancements, the data sharing between wasm apps, and between hosts can be more efficient and flexible. Admittedly shared heap management can be more complex for users, but it's similar to the zero-overhead principle. No overhead will be imposed for the users who don't use the shared heap enhancement or don't use the shared heap at all. |

Build wamrc AOT compiler
Both wasm binary file and AOT file are supported by iwasm. The wamrc AOT compiler is to compile wasm binary file to AOT file which can also be run by iwasm. You can execute following commands to build wamrc compiler:
For Linux(Ubuntu 20.04 as an example):
First, make sure necessary dependency are installed:
sudo apt-get install git build-essential cmake g++-multilib libgcc-9-dev lib32gcc-9-dev ccache
cd wamr-compiler
./build_llvm.sh (or "./build_llvm_xtensa.sh" to support xtensa target)
mkdir build && cd build
cmake .. (or "cmake .. -DWAMR_BUILD_PLATFORM=darwin" for MacOS)
make
# wamrc is generated under current directory
For Windows：
cd wamr-compiler
python build_llvm.py
mkdir build && cd build
cmake ..
cmake --build . --config Release
# wamrc.exe is generated under .\Release directory
