The Absurdity of Error Handling: Finding a Purpose for Errors in Safety-Critical SYCL

Explore the complexities of error handling in safety-critical SYCL systems through this 32-minute CppCon conference talk. Delve into the challenges of combining C++, error handling, and safety-critical software as Erik Tomusk, Senior Safety Architect at Codeplay Software, shares insights from the SYCL SC working group. Examine the technical and philosophical questions surrounding deterministic error handling in safety-critical contexts, and challenge your understanding of what constitutes an error. Gain a fresh perspective on C++ error handling beyond RTTI and stack unwinding, focusing on the differing concepts of safety in programming language design versus safety-critical systems. Apply these insights to improve error handling in general C++ software development and reconsider expected behaviors in the presence of errors.
