(s_weakref): New. * read.h (s_weakref): Declare. * struc-symbol.h (struct symbol): Add sy_weakrefr and sy_weakrefd. * symbols.c (colon): Clear weakrefr. (symbol_find_exact): Rename to, and reimplement in terms of... (symbol_find_exact_noref): ... new function. (symbol_find): Likewise... (symbol_find_noref): ... ditto. (resolve_symbol_value): Resolve weakrefr without setting their values. (S_SET_WEAK): Call hook. (S_GET_VALUE): Follow weakref link. (S_SET_VALUE): Clear weakrefr. (S_IS_WEAK): Follow weakref link. (S_IS_WEAKREFR, S_SET_WEAKREFR, S_CLEAR_WEAKREFR): New. (S_IS_WEAKREFD, S_SET_WEAKREFD, S_CLEAR_WEAKREFD): New. (symbol_set_value_expression, symbol_set_frag): Clear weakrefr. (symbol_mark_used): Follow weakref link. (print_symbol_value_1): Print weak, weakrefr and weakrefd. * symbols.h (symbol_find_noref, symbol_find_exact_noref): Declare. (S_IS_WEAKREFR, S_SET_WEAKREFR, S_CLEAR_WEAKREFR): Declare. (S_IS_WEAKREFD, S_SET_WEAKREFD, S_CLEAR_WEAKREFD): Declare. * write.c (adust_reloc_syms): Follow weakref link. Do not complain if target is undefined. (write_object_file): Likewise. Remove weakrefr symbols. Drop unreferenced weakrefd symbols. * config/obj-coff.c (obj_frob_symbol): Do not force WEAKREFD symbols EXTERNAL. (pecoff_obj_set_weak_hook, pecoff_obj_clear_weak_hook): New. * config/obj-coff.h (obj_set_weak_hook, obj_clear_weak_hook): Define. * doc/as.texinfo: Document weakref. * doc/internals.texi: Document new struct members, internal functions and hooks. gas/testsuite/ChangeLog: * gas/all/weakref1.s, gas/all/weakref1.d: New test. * gas/all/weakref1g.d, gas/all/weakref1l.d: New tests. * gas/all/weakref1u.d, gas/all/weakref1w.d: New tests. * gas/all/weakref2.s, gas/all/weakref3.s: New tests. * gas/all/gas.exp: Run new tests. --- gas/symbols.h | 8 ++++++++ 1 file changed, 8 insertions(+) (limited to 'gas/symbols.h') diff --git a/gas/symbols.h b/gas/symbols.h index c20f4d7330..99fa3c3c47 100644 --- a/gas/symbols.h +++ b/gas/symbols.h @@ -37,7 +37,9 @@ extern int symbols_case_sensitive; char *decode_local_label_name (char *s); symbolS *symbol_find (const char *name); +symbolS *symbol_find_noref (const char *name, int noref); symbolS *symbol_find_exact (const char *name); +symbolS *symbol_find_exact_noref (const char *name, int noref); symbolS *symbol_find_or_make (const char *name); symbolS *symbol_make (const char *name); symbolS *symbol_new (const char *name, segT segment, valueT value, @@ -83,6 +85,8 @@ extern void S_SET_VALUE (symbolS *, valueT); extern int S_IS_FUNCTION (symbolS *); extern int S_IS_EXTERNAL (symbolS *); extern int S_IS_WEAK (symbolS *); +extern int S_IS_WEAKREFR (symbolS *); +extern int S_IS_WEAKREFD (symbolS *); extern int S_IS_COMMON (symbolS *); extern int S_IS_DEFINED (symbolS *); extern int S_FORCE_RELOC (symbolS *, int); @@ -98,6 +102,10 @@ extern void S_SET_EXTERNAL (symbolS *); extern void S_SET_NAME (symbolS *, const char *); extern void S_CLEAR_EXTERNAL (symbolS *); extern void S_SET_WEAK (symbolS *); +extern void S_SET_WEAKREFR (symbolS *); +extern void S_CLEAR_WEAKREFR (symbolS *); +extern void S_SET_WEAKREFD (symbolS *); +extern void S_CLEAR_WEAKREFD (symbolS *); extern void S_SET_THREAD_LOCAL (symbolS *); extern void S_SET_VOLATILE (symbolS *); extern void S_SET_FORWARD_REF (symbolS *); -- cgit v1.2.1
