Hello,

I am trying to use a shader that is causing the adreno shader compiler to segfault. I have published a reproduction example with both the wgsl and compiled spirv vertex shaders. The shader has an entry point called "vertex_fn"

Please let me know if I can provide any more information to help debug this.

Thanks!

Kevin

What is the shader compiler issue details?

What platform? what GFX driver/Compiler version? what exact shader code?

Thanks
Bob Du

In my post I link to a GitHub with both the wgsl and spirv that crashes the compiler (the compiler segfaults). We had a discussion on a development discord about what seems to be triggering the issue in the compiler https://discord.com/channels/691052431525675048/829769375618826251/10074...

Please let me know if I can provide any additional information.

Thank you,

Kevin

Dear Customer

Can you post your discussion in this forum, then we can easiy check the discussion history?

Also can you check what is your current driver/compiler version on your device?

adb shell dumpsys SurfaceFlinger | grep GLES

or you can provide one complete logcat log when you reproduce the issue.

Thanks
Bob Du
