ld: Add '--require-defined' command line option. Add a new command line option '--require-defined' to the linker. This option operates identically to the '--undefined' option, except that if the symbol is not defined in the final output file then the linker will exit with an error. When making use of --gc-section, or just when trying to pull in parts of a library, it is not uncommon for a user to use the '--undefined' command line option to specify a symbol that the user then expects to be defined by one of the object files supplied to the link. However, if for any reason the symbol is not satisfied by an object provided to the link the user will be left with an undefined symbol in the output file, instead of a defined symbol. In some cases the above behaviour is what the user wants, in other cases though we can do better. The '--require-defined' option tries to fill this gap. The symbol passed to the '--require-defined' option is treated exactly as if the symbol was passed to '--undefined', however, before the linker exits a check is made that all symbols passed to '--require-defined' are actually defined, if any are not then the link will fail with an error. ld/ChangeLog: * ld.texinfo (Options): Document --require-defined option. * ldlang.c (struct require_defined_symbol): New structure. (require_defined_symbol_list): New variable. (ldlang_add_require_defined): New function. (ldlang_check_require_defined_symbols): New function.

ld: Extend options for altering orphan handling behaviour. Replace the options --warn-orphan and --no-warn-orphan with a single option --orphan-handling=MODE, where mode can be place, warn, error, and discard. Mode 'place' is the default, and is the current behaviour, placing the orphan section into a suitable output section. Mode 'warn' is the same as '--warn-orphan'. The orphan is also placed using the same algorithm as for 'place'. Mode 'error' is the same as '--warn-orphan' and '--fatal-warnings'. Mode 'discard' assigns all output sections to the /DISCARD/ section. ld/ChangeLog: * ld.h (enum orphan_handling_enum): New. (ld_config_type): Remove warn_orphan, add orphan_handling. * ldemul.c (ldemul_place_orphan): Remove warning about orphan sections. * ldlang.c (ldlang_place_orphan): New function.

(parse_args): Remove handling for OPTION_WARN_ORPHAN and OPTION_NO_WARN_ORPHAN, add handling for OPTION_ORPHAN_HANDLING. * NEWS: Replace text about --warn-orphan with --orphan-handling. * ld.texinfo (Options): Remove --warn-orphan entry and add entry on --orphan-handling. (Orphan Sections): Add reference to relevant command line options. ld/testsuite/ChangeLog: * ld-elf/elf.exp: Switch to rely on run_dump_test. * ld-elf/orphan-5.l: Update expected output. * ld-elf/orphan-5.d: New file. * ld-elf/orphan-6.d: New file. * ld-elf/orphan-6.l: New file. * ld-elf/orphan-7.d: New file. * ld-elf/orphan-7.map: New file. * ld-elf/orphan-8.d: New file. * ld-elf/orphan-8.map: New file.
