This commit updates all ICHECK macros to TVM_FFI_ICHECK in the Metal runtime implementation to align with the new FFI refactoring.

The changes include updating ICHECK, ICHECK_LT, ICHECK_EQ macros to their TVM_FFI_ICHECK equivalents across the following files:

  • src/runtime/metal/metal_device_api.mm
  • src/runtime/metal/metal_module.mm

This refactoring ensures consistency with the new TVM FFI interface and maintains the same error checking behavior while using the updated macro names.

Summary of Changes

Hello @ballinyouup, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request refactors the Metal runtime implementation to align with recent FFI changes. It systematically updates all instances of the older ICHECK macro family to the new TVM_FFI_ICHECK equivalents, ensuring consistency with the updated FFI interface while preserving the existing error checking logic.

Highlights

  • Macro Renaming: The ICHECK, ICHECK_LT, and ICHECK_EQ macros have been uniformly updated to their TVM_FFI_ICHECK counterparts (TVM_FFI_ICHECK, TVM_FFI_ICHECK_LT, TVM_FFI_ICHECK_EQ) across the Metal runtime files.

🧠 New Feature in Public Preview: You can now enable Memory to help Gemini Code Assist learn from your team's feedback. This makes future code reviews more consistent and personalized to your project's style. Click here to enable Memory in your admin console.
