Things that still need to be handled: -*- Text -*-
|
|||
|
|
|
|||
|
|
o - check all the swapping code.
|
|||
|
|
o - change the memory usage to reflect the message which follows the
|
|||
|
|
page break.
|
|||
|
|
o - implement bfd_abort, which should close the bfd but not alter the
|
|||
|
|
filesystem.
|
|||
|
|
o - remove the following obsolete functions:
|
|||
|
|
bfd_symbol_value
|
|||
|
|
bfd_symbol_name
|
|||
|
|
bfd_get_first_symbol
|
|||
|
|
bfd_get_next_symbol
|
|||
|
|
bfd_classify_symbol
|
|||
|
|
bfd_symbol_hasclass
|
|||
|
|
o - update the bfd doc; write a how-to-write-a-backend doc.
|
|||
|
|
o - change reloc handling as per Steve's suggestion.
|
|||
|
|
|
|||
|
|
|
|||
|
|
Changing the way bfd uses memory. The new convention is simple:
|
|||
|
|
|
|||
|
|
o - bfd will never write into user-supplied memory, nor attempt to
|
|||
|
|
free it.
|
|||
|
|
o - closing a bfd may reclaim all bfd-allocated memory associated
|
|||
|
|
with that bfd.
|
|||
|
|
- - bfd_target_list will be the one exception; you must reclaim the
|
|||
|
|
returned vector yourself.
|
|||
|
|
|
|||
|
|
Interface implications are minor (get_symcount_upper_bound will go
|
|||
|
|
away; bfd_cannicalize_symtab will allocate its own memory, etc).
|
|||
|
|
|
|||
|
|
Certain operations consume a lot of memory; for them manual
|
|||
|
|
reclaimation is available:
|
|||
|
|
|
|||
|
|
o - bfd_canonicalize_symtab will return a pointer to a
|
|||
|
|
null-terminated vector of symbols. Subsequent calls may or may
|
|||
|
|
not return the same pointer.
|
|||
|
|
bfd_canonicalize_relocs will do the same; returning a pointer to
|
|||
|
|
an array of arelocs. Calling this function will read symbols in
|
|||
|
|
too.
|
|||
|
|
|
|||
|
|
o - bfd_reclaim_relocs will free the memory used by these relocs.
|
|||
|
|
the symbols will be untouched.
|
|||
|
|
bfd_reclaim_symtab (ne bfd_reclaim_symbol_table) will free the
|
|||
|
|
memory allocated by canonialize_symtab.
|
|||
|
|
Since relocations point to symbols, any relocations obtained by a
|
|||
|
|
call to bfd_canonicalize_relocs will be reclaimed as well.
|
|||
|
|
|
|||
|
|
o - if you don't call the reclaim_ functions, the memory will be
|
|||
|
|
reclaimed at bfd_close time.
