I can confirm the same assert failure on Haswell.
I've also found a workaround that could point to the root cause.
================ CRASH ====================
#version 310 es
precision highp float;
in vec3 color;
layout(location = 0) out vec4 fragcolor;
void main()
{
fragcolor = vec4(color, 0.5);
}
===========================================
============== NO CRASH ===================
#version 310 es
precision highp float;
in vec4 color;
layout(location = 0) out vec4 fragcolor;
void main()
{
fragcolor = vec4(color.xyz, 0.5);
}
===========================================
Something about a non-vec4 input upsets the compiler. The same crash happens for vec2.
You may want to retest it. I had the same issue and if I remember correctly it was caused and fixed by this: https://github.com/LunarG/VulkanSamples/pull/73 I tried the 1.0.11 vulkan sdk download and it includes this fix so Hologram works for me, albeit very slow (Ivy Bridge, known issue). Apparently there is no binary distribution anymore, so: ./build_samples.sh cd samples/build/Sample-Programs/Hologram ./Hologram Right, 1.0.11 woks here on SKL too. |
