This only affects targets which use target_version (aarch64 and riscv).
gcc/c-family/ChangeLog:
* c-pretty-print.cc (pp_c_function_target_version): New function.
(pp_c_function_target_clones): New function.
* c-pretty-print.h (pp_c_function_target_version): New function.
(pp_c_function_target_clones): New function.
gcc/c/ChangeLog:
* c-objc-common.cc (c_tree_printer): Add printing of target_clone and
target_version in decl diagnostics.
gcc/cp/ChangeLog:
* cxx-pretty-print.h (pp_cxx_function_target_version): New macro.
(pp_cxx_function_target_clones): Ditto.
* error.cc (dump_function_decl): Add printing of target_clone and
target_version in decl diagnostics.
