Worked on the espressif/llvm-project repository to enhance the SPIR-V backend, focusing on both feature development and stability improvements over a two-month period. Addressed floating-point precision and code generation reliability by implementing SPIR-V FP controls and the SPV_INTEL_float_controls2 extension using C++ and LLVM IR. Improved parsing logic for floating-point decorations and modernized the translation API to simplify usage and avoid global variable writes. Fixed issues with global variable handling, module translation, and debug info generation to satisfy the SPIR-V verifier and prevent crashes. Updated the test suite for better environment targeting, ensuring robust validation across Vulkan and OpenCL workflows.

Jan 1, 2025January 2025: Stability and portability improvements to the SPIR-V backend in espressif/llvm-project. This sprint focused on correctness fixes to SPIR-V global variable handling, module translation, and debug info generation to satisfy the SPIR-V verifier and prevent crashes, along with test harness refinements and environment targeting. The translation API was modernized to simplify usage, and extension handling was adjusted to avoid unintended global writes. An optimization was introduced in extension selection to align with Intel tooling. Tests were aligned with the correct SPIR-V environments (spv1.4/spv1.5) and Vulkan/OpenCL differences, improving reliability across CI.
