Use rtx_expr_list for expr_status.x_forced_labels
gcc/
2014-08-27 David Malcolm <dmalcolm@redhat.com>
* function.h (struct expr_status): Strengthen field
"x_forced_labels" from rtx to rtx_expr_list *.
* cfgbuild.c (make_edges): Split local "x" into two locals,
strengthening one from rtx to rtx_expr_list *, and using methods
of said class.
* dwarf2cfi.c (create_trace_edges): Split local "lab" out; within
loop over forced_labels, introduce strengthen it from rtx to
rtx_expr_list *, using methods to clarify the code.
* jump.c (rebuild_jump_labels_1): Strengthen local "insn" from rtx
to rtx_expr_list *, using methods of said class to clarify the
code.
* reload1.c (set_initial_label_offsets): Split local "x" into two
per-loop variables, strengthening the first from rtx to
rtx_expr_list * and using methods.
