[vulkan] Fix Vulkan SIMT mappings for GPU loop vars. #8259
Conversation
accidentally used the fully qualified var name rather than the categorized vulkan intrinsic name.

Sadly, we missed this regression since we disabled the Vulkan backend from running on the build bots due to spurious errors when we were getting the last release out the door. With all the recent Vulkan fixes, perhaps we should reconsider turning them back on? @steven-johnson |

Confirmed that the SPIRV binary that's created during CodeGen when the generator is run, does not match the SPIRV binary that's passed to the runtime during the execution of the test. There's a semi regular pattern of bytes that have been overwritten (all binary values of |

Ah, that seems likely. But I'm not sure where this is coming from ... the binary gets injected into a buffer that's exposed through the |

Aha! Found it ... the host-side CodeGen that invokes the GPU runtime uses CodeGen_C to encode the GPU kernel source into a formatted string. I'll disable this formatting for Vulkan to avoid the text translation. |

Should we backport this to the 17.x release? |

Yes … I think both the GPU Vars and CodeGen_C string formatting are in v17.x |
