@section Architectures

BFD keeps one atom in a BFD describing the

architecture of the data attached to the BFD: a pointer to a

@code{bfd_arch_info_type}.

Pointers to structures can be requested independently of a BFD

so that an architecture's information can be interrogated

without access to an open BFD.

The architecture information is provided by each architecture package.

The set of default architectures is selected by the macro

@code{SELECT_ARCHITECTURES}.  This is normally set up in the

@file{config/@var{target}.mt} file of your choice.  If the name is not

defined, then all the architectures supported are included.

When BFD starts up, all the architectures are called with an

initialize method.  It is up to the architecture back end to

insert as many items into the list of architectures as it wants to;

generally this would be one for each machine and one for the

default case (an item with a machine field of 0).

BFD's idea of an architecture is implemented in @file{archures.c}.

@subsection bfd_architecture

@strong{Description}@*

This enum gives the object file's CPU architecture, in a

global sense---i.e., what processor family does it belong to?

Another field indicates which processor within

the family is in use.  The machine gives a number which

distinguishes different versions of the architecture,

containing, for example, 2 and 3 for Intel i960 KA and i960 KB,

and 68020 and 68030 for Motorola 68020 and 68030.

This structure contains information on architectures for use

within BFD.

  int bits_per_byte;

  enum bfd_architecture arch;

  unsigned long mach;

  const char *arch_name;

  const char *printable_name;

  unsigned int section_align_power;

  /* TRUE if this is the default machine for the architecture.

     The default arch should be the first entry for an arch so that

     all the entries for that arch can be accessed via @code{next}.  */

  const struct bfd_arch_info * (*compatible)

    (const struct bfd_arch_info *a, const struct bfd_arch_info *b);

@strong{Synopsis}

@example

const bfd_arch_info_type *bfd_scan_arch (const char *string);

@end example

@strong{Description}@*

Figure out if BFD supports any cpu which could be described with

the name @var{string}.  Return a pointer to an @code{arch_info}

structure if a machine is found, otherwise NULL.

@findex bfd_arch_list

@subsubsection @code{bfd_arch_list}

@strong{Synopsis}

@example

const char **bfd_arch_list (void);

@end example

@strong{Description}@*

Return a freshly malloced NULL-terminated vector of the names

of all the valid BFD architectures.  Do not modify the names.

@findex bfd_arch_get_compatible

@subsubsection @code{bfd_arch_get_compatible}

@strong{Synopsis}

@example

const bfd_arch_info_type *bfd_arch_get_compatible

   (const bfd *abfd, const bfd *bbfd, bfd_boolean accept_unknowns);

@end example

@strong{Description}@*

Determine whether two BFDs' architectures and machine types

are compatible.  Calculates the lowest common denominator

between the two architectures and machine types implied by

the BFDs and returns a pointer to an @code{arch_info} structure

describing the compatible machine.

@findex bfd_default_arch_struct

@subsubsection @code{bfd_default_arch_struct}

@strong{Description}@*

The @code{bfd_default_arch_struct} is an item of

@code{bfd_arch_info_type} which has been initialized to a fairly

generic state.  A BFD starts life by pointing to this

structure, until the correct back end has determined the real

architecture of the file.

@example

extern const bfd_arch_info_type bfd_default_arch_struct;

@end example

@findex bfd_set_arch_info

@subsubsection @code{bfd_set_arch_info}

@strong{Synopsis}

@example

void bfd_set_arch_info (bfd *abfd, const bfd_arch_info_type *arg);

@end example

@strong{Description}@*

Set the architecture info of @var{abfd} to @var{arg}.

@findex bfd_default_set_arch_mach

@subsubsection @code{bfd_default_set_arch_mach}

@strong{Synopsis}

@example

bfd_boolean bfd_default_set_arch_mach

   (bfd *abfd, enum bfd_architecture arch, unsigned long mach);

@end example

@strong{Description}@*

Set the architecture and machine type in BFD @var{abfd}

to @var{arch} and @var{mach}.  Find the correct

pointer to a structure and insert it into the @code{arch_info}

pointer.

@findex bfd_get_arch

architecture.

@findex bfd_get_mach

@subsubsection @code{bfd_get_mach}

@strong{Synopsis}

@example

Return the long type which describes the BFD @var{abfd}'s

machine.

@findex bfd_arch_bits_per_byte

@subsubsection @code{bfd_arch_bits_per_byte}

@strong{Synopsis}

@example

unsigned int bfd_arch_bits_per_byte (bfd *abfd);

@end example

@strong{Description}@*

Return the number of bits in one of the BFD @var{abfd}'s

architecture's bytes.
