1016,Avoidance of unaligned loads is overly conservative,igloo,,"On alpha, mips, mipsel and arm we do loads in a way that is safe even if they are unaligned (see `cLoad` in `compiler/cmm/PprC.hs`). We need this when, for example, we read things with `indexInt16OffAddr#` from `Addr#`s in alex-generated lexers, but most of the time we know that the address is aligned appropriately so loads are slower than they need be.

A better way to do this would be to make Load a `MachOp` parameterised by whether it's known to be aligned or not. Likewise, Store should be a `CallishMachOp`.",task,new,lowest,7.6.2,Compiler,6.6,,,,Unknown/Multiple,Unknown/Multiple,,Unknown,N/A,,,
