Allow self-assignment for absolute symbols defined in a linker script Modifies ld machinery tracking linker script assignments to notice all assignments, not just those symbols mentioned in DEFINED(). ld/ PR ld/14962 * ldlang.h (struct lang_definedness_hash_entry): Add by_object and by_script. Make iteration a single bit field. (lang_track_definedness, lang_symbol_definition_iteration): Delete. (lang_symbol_defined): Declare. * ldlang.c (lang_statement_iteration): Expand comment a little. (lang_init <lang_definedness_table>): Make it bigger. (lang_track_definedness, lang_symbol_definition): Delete. (lang_definedness_newfunc): Update. (lang_symbol_defined): New function. (lang_update_definedness): Create entries here. Do track whether script definition of symbol is valid, even when also defined in an object file. * ldexp.c (fold_name <DEFINED>): Update. (fold_name <NAME>): Allow self-assignment for absolute symbols defined in a linker script. ld/testsuite/ * ld-scripts/pr14962-2.d, * ld-scripts/pr14962-2.t: New test. * ld-scripts/expr.exp: Run it.

.text TOTO :

x = ABSOLUTE(TOTO);
Correct script input section pattern We don't want this to match .rela.text or similar. * testsuite/ld-scripts/pr14962-2.t: Match .text, not *.text. * testsuite/ld-scripts/rgn-at5.t: Similarly, .sec not *.sec. * testsuite/ld-scripts/section-match-1.t: Likewise.
