Using wamrc for target aarch64 throws an error

[schorg]

I have a C application, compiled with wasi-sdk to wasm.
When I try to aot compile for target architecture aarch64 I get the following error:

➜ wamrc --target=aarch64 -o demo_io.aot demo_io.wasm
Create AoT compiler with:
  target:        aarch64v8
  target cpu:    
  cpu features:  
  opt level:     3
  size level:    1
  output format: AoT file
LLVM ERROR: Only small, tiny and large code models are allowed on AArch64
[1]    69636 abort      wamrc --target=aarch64 -o demo_io.aot demo_io.wasm

Any idea, how to fix this? Thanks for any hints.

yes, medium code model is not supported on AArch64 (and it's apparently the default one for MacOS and Windows). You can try experimenting with different models by passing --size-level= parameters to wamrc

I'll try again to aot-compile on Linux, if this helps.

[loganek]

you can also try it on macos/windows by setting --size-level parameter (e.g. --size-level=3 will set the code model to Small, which is supported on AArch64 IIRC)

I am working on a Mac M1, but I have also a VM with Ubuntu running. I compiled wamrc on the VM and it worked.
I will later try your proposal on MacOS. But for now my problem is solved.
Thank you very much.

If you change the size level you'll be able to compile on your Mac M1, but then you'll have problems running it #1365. I usually use my Linux machine for AOT.
