dsymutil cannot process static libraries (.a files), causing the build to fail when building tvm_runtime as a static library for iOS. Only run dsymutil on tvm_runtime when building the shared library variant.

Summary of Changes

Hello @MasterJH5574, 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 addresses a specific build issue encountered on Apple platforms when compiling tvm_runtime as a static library. By introducing a conditional check in the CMake configuration, the dsymutil tool, which is incompatible with static libraries, is now correctly bypassed in this scenario, ensuring successful compilation.

Highlights

  • Build Fix for Apple Platforms: Resolved a build failure on Apple platforms that occurred when tvm_runtime was configured as a static library. The dsymutil tool, which is incompatible with static libraries, was being incorrectly applied, leading to compilation errors.
  • Conditional dsymutil Application: Modified the CMakeLists.txt to conditionally apply dsymutil to tvm_runtime. It will now only run when tvm_runtime is built as a shared library, by checking if(NOT BUILD_STATIC_RUNTIME).

🧠 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.

Changelog
  • CMakeLists.txt
    • Added a conditional if(NOT BUILD_STATIC_RUNTIME) block around the tvm_ffi_add_apple_dsymutil(tvm_runtime) call. This prevents dsymutil from being executed when tvm_runtime is built as a static library.

Code Review

This pull request addresses a build failure on Apple platforms when tvm_runtime is configured as a static library. The dsymutil tool fails on static archives, and this change correctly adds a condition to only execute dsymutil for tvm_runtime when it's being built as a shared library. The fix is straightforward, correct, and aligns with the project's build logic. No issues were found.
