Constant Summary

FLAG_LOCAL =

From bfd.h: ‘The symbol has local scope; <<static>> in <<C>>. The value is the offset into the section of the data.’

'LOCAL'

FLAG_GLOBAL =

From bfd.h: ‘The symbol has global scope; initialized data in <<C>>. The value is the offset into the section of the data.’

'GLOBAL'

FLAG_DEBUG =

From bfd.h: ‘The symbol is a debugging record. The value has an arbitrary meaning, unless BSF_DEBUGGING_RELOC is also set.’

'DEBUGGING'

FLAG_FUNC =

From bfd.h: ‘The symbol denotes a function entry point. Used in ELF, perhaps others someday.’

'FUNCTION'

FLAG_WEAK =

From bfd.h: ‘A weak global symbol, overridable without warnings by a regular global symbol of the same name.’

'WEAK'

FLAG_SEC =

From bfd.h: ‘This symbol was created to point to a section, e.g. ELF’s STT_SECTION symbols.‘

'SECTION_SYM'

FLAG_CTOR =

From bfd.h: ‘Signal that the symbol is the label of constructor section.’

'CONSTRUCTOR'

FLAG_INDIRECT =

From bfd.h: ‘Signal that the symbol is indirect. This symbol is an indirect pointer to the symbol with the same name as the next symbol.’

'INDIRECT'

FLAG_FILE =

From bfd.h: ‘BSF_FILE marks symbols that contain a file name. This is used for ELF STT_FILE symbols.’

'FILE'

FLAG_DYNAMIC =

From bfd.h: ‘Symbol is from dynamic linking information.’

'DYNAMIC'

FLAG_OBJ =

From bfd.h: ‘The symbol denotes a data object. Used in ELF, and perhaps others someday.’

'OBJECT'

FLAG_THREAD =

From bfd.h: ‘This symbol is thread local. Used in ELF.’

'THREAD_LOCAL'

FLAGS =

Symbol flags. Defined in /usr/include/bfd.h : typedef struct bfd_symbol. From bfd.h: ‘A normal C symbol would be one of:

<<BSF_LOCAL>>, <<BSF_COMMON>>,  <<BSF_UNDEFINED>> or
<<BSF_GLOBAL>>.'
