PR c/34668
* gimplify.c (fold_indirect_ref_rhs): Rename to ...
(gimple_fold_indirect_ref_rhs): ... this.
(gimple_fold_indirect_ref): New function with foldings
that preserve lvalueness.
(gimplify_modify_expr_rhs): Call gimple_fold_indirect_ref_rhs.
* tree-flow.h (gimple_fold_indirect_ref): Declare.
* tree-inline.c (copy_body_r): Use gimple_fold_indirect_ref
to fold an INDIRECT_REF, fall back to the old use of
fold_indirect_ref_1.
* gcc.dg/pr34668-1.c: New test.
* gcc.dg/pr34668-2.c: Likewise.
