VkRunner test showing crash
When compiling a geometry shader with double inputs and outputs I get an LLVM
fatal error:
LLVM ERROR: Cannot select: 0x55de91ee9320: v2i32 = bitcast 0x55de91ee9048

In function: main
with this geometry shader:
#version 450 core
layout(triangles) in;
layout(triangle_strip, max_vertices = 3) out;
layout(location = 0) in double InDouble[3];
layout(location = 0) out double OutDouble;
void main() {
gl_Position = vec4(0);
for(int i = 0; i < 3; i++) {
OutDouble = InDouble[i];
EmitVertex();
}
EndPrimitive();
}
I've attached a VkRunner test which shows the crash.</pre>
