-DESCRIPTION
- These macros as used for reading and writing raw data in
- sections; each access (except for bytes) is vectored through
- the target format of the BFD and mangled accordingly. The
- mangling performs any necessary endian translations and
- removes alignment restrictions. Note that types accepted and
- returned by these macros are identical so they can be swapped
- around in macros---for example, @file{libaout.h} defines <<GET_WORD>>
- to either <<bfd_get_32>> or <<bfd_get_64>>.
-
- In the put routines, @var{val} must be a <<bfd_vma>>. If we are on a
- system without prototypes, the caller is responsible for making
- sure that is true, with a cast if necessary. We don't cast
- them in the macro definitions because that would prevent <<lint>>
- or <<gcc -Wall>> from detecting sins such as passing a pointer.
- To detect calling these with less than a <<bfd_vma>>, use
- <<gcc -Wconversion>> on a host with 64 bit <<bfd_vma>>'s.
