bool boring_symbol ( op_bfd_symbol const &  first,
op_bfd_symbol const &  second 
)

return true if the first symbol is less interesting than the second symbol boring symbol are eliminated when multiple symbol exist at the same vma

References op_bfd_symbol::hidden(), op_bfd_symbol::name(), and op_bfd_symbol::weak().

bfd* fdopen_bfd ( std::string const &  file,
int  fd 
)

open the given BFD from the fd

linenr_info const find_nearest_line ( bfd_info const &  ibfd,
op_bfd_symbol const &  sym,
bfd_vma  offset,
bool  anon_obj 
)

Attempt to locate a filename + line number for the given symbol and offset.

The bfd object is either the object associated with the binary or the once associated with the separated debug info file so find_nearest_line() can't lookup the section contents of code section etc. The filepos of debuginfo symbols are different from the original file but we fixed symbol filepos earlier.

bool find_separate_debug_file ( bfd *  ibfd,
std::string const &  filepath_in,
std::string &  debug_filename,
extra_images const &  extra 
)
bool interesting_symbol ( asymbol *  sym  ) 

Return true if the symbol is worth looking at.

bfd* open_bfd ( std::string const &  file  ) 

open the given BFD

bfd* spu_open_bfd ( std::string const   name,
int  fd,
uint64_t  offset_to_spu_elf 
)

Return a BFD for an SPU ELF embedded in PPE binary file.
