@defmac MAX_INTEGER_COMPUTATION_MODE
Define this to the largest integer machine mode which can be used for
operations other than load, store and copy operations.
You need only define this macro if the target holds values larger than
@code{word_mode} in general purpose registers. Most targets should not define
this macro.

Define this macro as a C string constant for the linker argument to link
