--- Comment #6 from Tobias Burnus <burnus at gcc dot gnu.org> --- Comment on attachment 53362 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=53362 gcc13-pr106449.patch > + t = fold_convert (sizetype, fd->loops[i + 1].n1); > + t = fold_build_pointer_plus (t2, t); I think the first line is not needed, given that fold_build_pointer_plus_loc has: return fold_build2_loc (loc, POINTER_PLUS_EXPR, TREE_TYPE (ptr), ptr, convert_to_ptrofftype_loc (loc, off)); and the convert_to_ptrofftype_loc does: if (ptrofftype_p (TREE_TYPE (off))) return off; return fold_convert_loc (loc, sizetype, off); where the last line matches your first line. Hence, just calling t = fold_build_pointer_plus (t2, fd->loops[i + 1].n1); should gives the same result and is more compact (avoids a line and a 2-character indent).
