FAQPage Schema
How do I add a new API to the .NET JIT-VM interface?▼

To add a new JIT-VM API, modify C++ and C# source files across the .NET runtime codebase. This includes updating header, implementation, and tooling source files to integrate the new function correctly.

What is the JIT-VM interface in the .NET runtime?▼

The JIT-VM interface handles communication between the JIT compiler and the .NET runtime. Extending it involves precise code changes across multiple files to enable new functional capabilities.

Do I need to update SuperPMI when extending the JIT-VM interface?▼

Yes, updating SuperPMI is necessary when extending the JIT-VM interface. This ensures the JIT performance analysis tooling remains compatible with the new API for performance testing.

What programming languages are involved in modifying the JIT-VM interface?▼

Modifying the JIT-VM interface requires changes in C++, C#, and SuperPMI tooling. These modifications span across header files, implementation files, and tooling source files.

Can I automate JIT-VM API integration across multiple .NET runtime files?▼

Yes, this Skill automates the integration of new APIs into the JIT-VM interface. It provides a step-by-step walkthrough to ensure all necessary code changes are made correctly across the codebase.
