[LLVMdev] Is there pass to break down <4 x float> to scalars
Hi, Richard,
I think we are solving a same problem. I am working on shader language
too. I am not satisfied with current binaries because vector operations
are kept in llvm opt.
glsl shader language has an operation called "swizzle". It can select
sub-components of a vector. If a shader only takes components "xy" for a
vec4. it's certainly wasteful to generate 4
