What does dynamic_vector_bytes
represent in TargetIsa
? All targets seem to have it set to constant 16 yet it takes value types as a parameter. Is it for SIMD support? What is intended if SIMD is not supported?
That's part of the "dynamic vector types" support, which is a way to support scalable-vector extensions (like SVE on aarch64) with a vector width that's configurable either as a setting on the compiler (target ISA level) or dynamically at runtime
for now you can just stub it with whatever the other backends are doing and it should be fine
