<Lynne> IndecisiveTurtle: you need that extension to "properly" support debugprintf
<Lynne> the extension literally says the driver can handle spirv it doesn't recognize, which any sanely written driver does

<IndecisiveTurtle> Lynne: I see, but well I can't use debugprintf on my system at all because of it, when it did work fine before. I guess the question would be if it is acceptable to have the old "non-proper" debugprintf support when a driver doesnt expose this extension
<Lynne> IndecisiveTurtle: just apply https://0x0.st/XUVQ.diff
<Lynne> or update drivers? its been 4 months or so, with how fast everything moves its been a while
<IndecisiveTurtle> I was hoping for a solution that would avoid a local patch, but I guess compiling mesa from source is better, since the arch package is months old

<thardin> didn't know vulkan could do such things
<Lynne> its not about vulkan, its about glsl
<Lynne> these days you have I-can't-believe-its-not-a-pointer but its pretty hard to use
<Lynne> I looked into slang and I'll definitely port ALL the vulkan code we have to slang once its reasonably stable
