911 A macro to update M and UNSIGNEDP when an object whose type is
912 TYPE and which has the specified mode and signedness is to be
913 stored in a register. This macro is only called when TYPE is a
914 scalar type.
915
916 On most RISC machines, which only have operations that operate on
917 a full register, define this macro to set M to `word_mode' if M is
918 an integer mode narrower than `BITS_PER_WORD'. In most cases,
919 only integer modes should be widened because wider-precision
920 floating-point operations are usually more expensive than their
921 narrower counterparts.
922
923 For most machines, the macro definition does not change UNSIGNEDP.
924 However, some machines, have instructions that preferentially
925 handle either signed or unsigned quantities of certain modes. For
926 example, on the DEC Alpha, 32-bit loads from memory and 32-bit add
927 instructions sign-extend the result to 64 bits. On such machines,
928 set UNSIGNEDP according to which kind of extension is more
929 efficient.
930
