Since the previous commit 6924c00c8710ec95834e21f8d68b10f2d09a8680 ("xtensa:
Make all memory constraints special"), it has been discovered that the
definition of TARGET_DIFFERENT_ADDR_DISPLACEMENT_P, which was previously
introduced to obtain appropriate memory reference displacements (commit
211459e12147e9ed42c0a0947b1b95b551e03ef3), is no longer necessary. In other
words:
- The order of the movsi_internal MD pattern alternatives has been re-
arranged so that memory references with shorter displacements take
precedence
- Furthermore, since all memory constraints are now "special," address
reload operations that explicitly add the displacement to the base
register and then adopt a 0-displacement reference are no longer
performed and are simply skipped
Therefore, this patch removes the definition of
TARGET_DIFFERENT_ADDR_DISPLACEMENT_P.
gcc/ChangeLog:
