## Cmm layer
Our `CmmType` representation for vectors differs slightly from the proposal. See [cmm/CmmType.hs](/ghc/ghc/tree/master/compiler/cmm/CmmType.hs?rev=e42746d07239888c74e937046fadf93655b44b65#L42)[](/trac/ghc/export/HEAD/ghc/compiler/cmm/CmmType.hs#L42).

The implementation differs from the proposal in its naming scheme. We wanted to avoid overloading the term "vector," so, e.g., a 4-wide SIMD vector of `Float#`s is a `FloatX4#`.

Not everything in the proposal is implemented, but we do have a useful subset.
