--- Comment #1 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Iain Buclaw <ibuc...@gcc.gnu.org>: https://gcc.gnu.org/g:c77230856eac2d28eb7bf10985846885c3c8727b commit r12-1993-gc77230856eac2d28eb7bf10985846885c3c8727b Author: Iain Buclaw <ibuc...@gdcproject.org> Date: Sat Jul 3 00:13:29 2021 +0200 d: RHS value lost when a target_expr modifies LHS in a cond_expr To prevent the RHS of an assignment modifying the LHS before the assignment proper, a target_expr is forced so that function calls that return with slot optimization modify the temporary instead. This did not work for conditional expressions however, to give one example. So now the RHS is always forced to a temporary. PR d/101282 gcc/d/ChangeLog: * d-codegen.cc (build_assign): Force target_expr on RHS for non-POD assignment expressions. gcc/testsuite/ChangeLog: * gdc.dg/torture/pr101282.d: New test.
