What Hacker News says
3 sourcesIt's clear that vendors do have a serious interest in supporting SPIR-V as specified, not just SPIR-V as produced by glslang. I can assure you that I have reliable sources for that, though obviously it's up to you whether you want to believe a random internet person.
Also, the Vulkan Conformance Test Suite is open source.[0] Contributions of better SPIR-V tests would certainly be accepted, so Google (or anybody else, really) has an easy path towards forcing better support in drivers if they care sufficiently.

In Introducing Zink: OpenGL on Vulkanhttps://people.freedesktop.org/~nh/piglit/ is an extensive open conformance test suite for opengl. Khronos has their own (https://github.com/KhronosGroup/VK-GL-CTS, used to be proprietary), but judging by the amount of bugs and piglit failures in drivers which supposedly pass it, I think it's probably not very useful.
