I write a Mesa-IR to SPIR-V Translator, and it's fine on NVIDIA and Adreno driver.
But It's crash on MALI driver, so I found the problem is I lost add gl_Position..
That is, SPIRV-Tools should enforce, for every entrypoint:
Every id listed in the entrypoint is for an OpVariable in the Input or Output storage class.
The static call graph rooted at that entrypoint does not reference any /other/ OpVariables in the Input or Output storage class which are not listed in the entrypoint. (your case)
Hi
I write a Mesa-IR to SPIR-V Translator, and it's fine on NVIDIA and Adreno driver. But It's crash on MALI driver, so I found the problem is I lost add gl_Position..
OpEntryPoint Vertex %6 "main" %13 I lost the %13.
It's crash on MALI Offline Shader Compiler also.
Thanks
