--- Comment #4 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Author: jakub Date: Thu Nov 23 11:26:32 2017 New Revision: 255095 URL: https://gcc.gnu.org/viewcvs?rev=255095&root=gcc&view=rev Log: PR middle-end/82253 * expr.c (expand_assignment): For CONCAT to_rtx, complex type from and bitpos/bitsize covering the whole destination, use store_expr only if the complex mode is the same. Otherwise, use expand_normal and if it returns CONCAT, subreg each part separately instead of trying to subreg the whole result. * gfortran.dg/pr82253.f90: New test. Added: trunk/gcc/testsuite/gfortran.dg/pr82253.f90 Modified: trunk/gcc/ChangeLog trunk/gcc/expr.c trunk/gcc/testsuite/ChangeLog
