wamrc --help
Usage: wamrc [options] -o output_file wasm_file
--target=<arch-name> Set the target arch, which has the general format: <arch><sub>
<arch> = x86_64, i386, aarch64, arm, thumb, xtensa, mips.
<arch> = x86_64, i386, aarch64, arm, thumb, xtensa, mips,
riscv64, riscv32.
Default is host arch, e.g. x86_64
<sub> = for ex. on arm or thumb: v5, v6m, v7a, v7m, etc.
Use --target=help to list supported targets
--target-abi=<abi> Set the target ABI, e.g. gnu, eabi, gnueabihf, etc. (default: gnu)
--target-abi=<abi> Set the target ABI, e.g. gnu, eabi, gnueabihf, msvc, etc.
Default is gnu if target isn't riscv64 or riscv32
For target riscv64 and riscv32, default is lp64d and ilp32d
Use --target-abi=help to list all the ABI supported
--cpu=<cpu> Set the target CPU (default: host CPU, e.g. skylake)
Use --cpu=help to list all the CPU supported
