Storage Image Multisample when ingesting SPIR-V is unsupported #8269
Description
When writing a simple resolve shader, that resolved a multi sampled texture (example in Slang):
#language slang 2026
[[vk::binding(0, 0)]] var texture: Texture2DMS;
[[shader("pixel")]]
func fs_main(float4 position : SV_Position) -> float4 {
let pixel_coord = int2(position.xy);
var color: float4;
for (var index: int = 0; index < 8; index++) {
color += texture.Load(pixel_coord, index);
}
color = color / 8.0;
return color;
}Then naga throws this error:
UnsupportedCapability(StorageImageMultisample)
I will write PR to solve this issue, since it seems that naga is actually implementing loading from multi samples textures just fine.
