------- Comment #22 from dje at gcc dot gnu dot org 2006-01-03 15:22 ------- Is it possible for backends to inquire how many reciprocals were discovered? PowerPC and IA-64 have reciprocal instructions and could benefit by choosing to generate reciprocal earlier with additional information about the number of divides calculated. For PowerPC, it is effective to use the instruction if there are multiple divides, such as the three divisions mentioned above. The IBM XLC compiler propagates the reciprocal and numerator pair through its equivalent to RTL.
