• Great Flexibility• Expensive to rewrite

large amounts of code

• Greatest breadth and impact

• Sensitive to quality and performance

Tremendous leverage!

Observations

▪ Vulkan and SPIR-V today are sufficient to host compute shaders written in novel languages

▪ In the App+Driver+Compiler triad, the compiler has huge advantages!

▪ Clspv has allowed us to compile several hundred thousand lines of OpenCL C code to SPIR-V (graphics) with minimal changes

▪ The Clspv experience revealed coverage gaps in Vulkan CTS

▪ We have improved CTS coverage

▪ Compilers are remarkably agile for working around bugs in drivers

▪ Clspv is today an insanely useful prototype with which I’m building a commercial Android product
