55 | The file @code{aoutf1.h} contains the code for BFD's | |
56 | a.out back end. Control over the generated back end is given by these | |
57 | two preprocessor names: | |
58 | @table @code | |
59 | @item ARCH_SIZE | |
60 | This value should be either 32 or 64, depending upon the size of an | |
61 | int in the target format. It changes the sizes of the structs which | |
62 | perform the memory/disk mapping of structures. | |
63 | ||
64 | The 64 bit backend may only be used if the host compiler supports 64 | |
ce6821a5 | 65 | ints (eg long long with gcc), by defining the name @code{BFD_HOST_64_BIT} in @code{bfd.h}. |
3f2255e7 SG |
66 | With this name defined, @emph{all} bfd operations are performed with 64bit |
67 | arithmetic, not just those to a 64bit target. | |
