30 SECTION
31 Architectures
33 BFD keeps one atom in a BFD describing the
34 architecture of the data attached to the BFD: a pointer to a
35 <<bfd_arch_info_type>>.
37 Pointers to structures can be requested independently of a BFD
38 so that an architecture's information can be interrogated
39 without access to an open BFD.
41 The architecture information is provided by each architecture package.
42 The set of default architectures is selected by the macro
43 <<SELECT_ARCHITECTURES>>. This is normally set up in the
44 @file{config/@var{target}.mt} file of your choice. If the name is not
45 defined, then all the architectures supported are included.
47 When BFD starts up, all the architectures are called with an
48 initialize method. It is up to the architecture back end to
49 insert as many items into the list of architectures as it wants to;
50 generally this would be one for each machine and one for the
51 default case (an item with a machine field of 0).
53 BFD's idea of an architecture is implemented in @file{archures.c}.

61 DESCRIPTION
62 This enum gives the object file's CPU architecture, in a
63 global sense---i.e., what processor family does it belong to?
64 Another field indicates which processor within
65 the family is in use. The machine gives a number which
66 distinguishes different versions of the architecture,
67 containing, for example, 2 and 3 for Intel i960 KA and i960 KB,
68 and 68020 and 68030 for Motorola 68020 and 68030.

1081 const bfd_arch_info_type *bfd_get_arch_info (bfd *abfd);
1083 DESCRIPTION
1084 Return the architecture info struct in @var{abfd}.

1095 bfd_lookup_arch
1097 SYNOPSIS
1098 const bfd_arch_info_type *bfd_lookup_arch
1099 (enum bfd_architecture arch, unsigned long machine);
1101 DESCRIPTION
1102 Look for the architecture info structure which matches the
1103 arguments @var{arch} and @var{machine}. A machine of 0 matches the
1104 machine/architecture structure which marks itself as the
1105 default.

1131 SYNOPSIS
1132 const char *bfd_printable_arch_mach

1135 DESCRIPTION
1136 Return a printable string representing the architecture and
1137 machine type.

1153 FUNCTION
1154 bfd_octets_per_byte
1156 SYNOPSIS
1157 unsigned int bfd_octets_per_byte (bfd *abfd);
1159 DESCRIPTION
1160 Return the number of octets (8-bit quantities) per target byte
1161 (minimum addressable unit). In most cases, this will be one, but some
1162 DSP targets have 16, 32, or even 48 bits per byte.
