Adjust comment. * tree.h (SWITCH_LABELS): Remove. * gimplify.c (gimplify_switch_expr): Don't test SWITCH_LABELS, assert SWITCH_BODY is non-NULL. * tree-pretty-print.c (dump_generic_node): Remove SWITCH_LABELS handling. * tree.c (block_may_fallthru): Always return true; for SWITCH_EXPR. c/ * c-typeck.c (c_start_case): Build SWITCH_EXPR using build2 instead of build3. cp/ * cp-gimplify.c (genericize_switch_stmt): Build SWITCH_EXPR using build2_loc instead of build3_loc. ada/ * gcc-interface/trans.c (Case_Statement_to_gnu): Build SWITCH_EXPR using build2 instead of build3. jit/ * jit-playback.c (add_switch): Build SWITCH_EXPR using build2 instead of build3. Formatting fixes. Adjust funciton comment. fortran/ * trans-decl.c (gfc_trans_entry_master_switch): Build SWITCH_EXPR using fold_build2_loc instead of fold_build3_loc. * trans-io.c (io_result): Likewise. * trans-stmt.c (gfc_trans_integer_select, gfc_trans_character_select): Likewise. go/ * go-gcc.cc (Gcc_backend::switch_statement): Build SWITCH_EXPR using build2_loc instead of build3_loc. brig/ * brigfrontend/brig-branch-inst-handler.cc (brig_branch_inst_handler::operator): Build SWITCH_EXPR using build2 instead of build3.
