Often when writing complex instruction definitions in an ad file temporary registers are needed for code generation. KILLs can be use in some cases but this requires having a fixed register for the temporary which overly constrains the regiser allocator resulting in more shuffling of registers than is really necessary. This is particularly noticeable in i486.ad.
