The code to access the target section table can be made more const, so lets do that. There should be no user visible changes after this commit. gdb/ChangeLog: * gdb/bfd-target.c (class target_bfd) <get_section_table>: Make return type const. * gdb/exec.c (struct exec_target) <get_section_table>: Likewise. (section_table_read_available_memory): Make local const. (exec_target::xfer_partial): Make local const. (print_section_info): Make parameter const. * gdb/exec.h (print_section_info): Likewise. * gdb/ppc64-tdep.c (ppc64_convert_from_func_ptr_addr): Make local const. * gdb/record-btrace.c (record_btrace_target::xfer_partial): Likewise. * gdb/remote.c (remote_target::remote_xfer_live_readonly_partial): Likewise. * gdb/s390-tdep.c (s390_load): Likewise. * gdb/solib-dsbt.c (scan_dyntag): Likewise. * gdb/solib-svr4.c (scan_dyntag): Likewise. * gdb/target-debug.h (target_debug_print_target_section_table_p): Rename to... (target_debug_print_const_target_section_table_p): ...this. * gdb/target-delegates.c: Regenerate. * gdb/target.c (target_get_section_table): Make return type const. (target_section_by_addr): Likewise. Also make some locals const. (memory_xfer_partial_1): Make some locals const. * gdb/target.h (struct target_ops) <get_section_table>: Make return type const. (target_section_by_addr): Likewise. (target_get_section_table): Likewise.
