--- Comment #6 from Paul Thomas <pault at gcc dot gnu.org> --- Author: pault Date: Mon Oct 26 17:25:03 2015 New Revision: 229386 URL: https://gcc.gnu.org/viewcvs?rev=229386&root=gcc&view=rev Log: 2015-10-26 Paul Thomas <pa...@gcc.gnu.org> PR fortran/67177 PR fortran/67977 * primary.c (match_substring): Add an argument 'deferred' to flag that a substring reference with null start and end should not be optimized away for deferred length strings. (match_string_constant, gfc_match_rvalue): Set the argument. * trans-expr.c (alloc_scalar_allocatable_for_assignment): If there is a substring reference return. * trans-intrinsic.c (conv_intrinsic_move_alloc): For deferred characters, assign the 'from' string length to the 'to' string length. If the 'from' expression is deferred, set its string length to zero. If the 'to' expression has allocatable components, deallocate them. 2015-10-26 Paul Thomas <pa...@gcc.gnu.org> PR fortran/67177 * gfortran.dg/move_alloc_15.f90: New test * gfortran.dg/move_alloc_16.f90: New test PR fortran/67977 * gfortran.dg/deferred_character_assignment_1.f90: New test Added: branches/gcc-5-branch/gcc/testsuite/gfortran.dg/deferred_character_assignment_1.f90 branches/gcc-5-branch/gcc/testsuite/gfortran.dg/move_alloc_15.f90 branches/gcc-5-branch/gcc/testsuite/gfortran.dg/move_alloc_16.f90 Modified: branches/gcc-5-branch/gcc/fortran/ChangeLog branches/gcc-5-branch/gcc/fortran/primary.c branches/gcc-5-branch/gcc/fortran/trans-expr.c branches/gcc-5-branch/gcc/fortran/trans-intrinsic.c branches/gcc-5-branch/gcc/testsuite/ChangeLog
