| The file @code{aoutf1.h} contains the code for BFD's |
| a.out back end. Control over the generated back end is given by these |
| two preprocessor names: |
| @table @code |
| @item ARCH_SIZE |
| This value should be either 32 or 64, depending upon the size of an |
| int in the target format. It changes the sizes of the structs which |
| perform the memory/disk mapping of structures. |
| |
| The 64 bit backend may only be used if the host compiler supports 64 |
| ints (eg long long with gcc), by defining the name @code{BFD_HOST_64_BIT} in @code{bfd.h}. |
| With this name defined, @emph{all} bfd operations are performed with 64bit |
| arithmetic, not just those to a 64bit target. |
