Make wamrc normalize "arm64" to "aarch64v8". Previously the only way to make the "arm64" target was to not specify a target on 64 bit arm-based mac builds. Now arm64 and aarch64v8 are treated as the same. Make aot_loader accept "aarch64v8" on arm-based apple (as well as accepting legacy "arm64" based aot targets). This also removes __APPLE__ and __MACH__ from the block that defaults size_level to 1 since it doesn't seem to be supported for aarch64: `LLVM ERROR: Only small, tiny and large code models are allowed on AArch64`
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
