--- Comment #23 from Thomas Koenig <tkoenig at gcc dot gnu.org> 2010-12-03 10:35:16 UTC --- Author: tkoenig Date: Fri Dec 3 10:35:12 2010 New Revision: 167413 URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=167413 Log: 2010-12-02 Thomas Koenig <[email protected]> PR fortran/45159 * dependency.c (check_section_vs_section): Pre-calculate the relationship between the strides and the relationship between the start values. Use an integer constant one for that purpose. Forward dependencies for positive strides apply for where the lhs start <= rhs start and lhs stride <= rhs stride and vice versa for negative stride. No need to compare end expressions in either case (assume no bounds violation). 2010-12-02 Thomas Koenig <[email protected]> PR fortran/45159 * gfortran.dg/dependency_38.f90: New test.
