42 | The file @code{aoutf1.h} contains the code for BFD's |
43 | a.out back end. Control over the generated back end is given by these | |
4f8b8627 | 44 | two preprocessor names: |
6f715d66 | 45 | @table @code |
4f8b8627 | 46 | @item ARCH_SIZE |
6f715d66 SC |
47 | This value should be either 32 or 64, depending upon the size of an |
48 | int in the target format. It changes the sizes of the structs which | |
49 | perform the memory/disk mapping of structures. | |
50 | ||
51 | The 64 bit backend may only be used if the host compiler supports 64 | |
4f8b8627 JG |
52 | ints (eg long long with gcc), by defining the name @code{HOST_64_BIT} in @code{bfd.h}. |
53 | With this name defined, @emph{all} bfd operations are performed with 64bit | |
6f715d66 SC |
54 | arithmetic, not just those to a 64bit target. |

56 | @item TARGETNAME | |
