  79. <h3 class="section">2.13 Architectures</h3>

  80. <p>BFD keeps one atom in a BFD describing the

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

  82. <code>bfd_arch_info_type</code>.

  83. </p>

  84. <p>Pointers to structures can be requested independently of a BFD

  85. so that an architecture&rsquo;s information can be interrogated

  86. without access to an open BFD.

  87. </p>

  88. <p>The architecture information is provided by each architecture package.

  89. The set of default architectures is selected by the macro

  90. <code>SELECT_ARCHITECTURES</code>.  This is normally set up in the

  91. <samp>config/<var>target</var>.mt</samp> file of your choice.  If the name is not

  92. defined, then all the architectures supported are included.

  93. </p>

  94. <p>When BFD starts up, all the architectures are called with an

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

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

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

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

  99. </p>

  100. <p>BFD&rsquo;s idea of an architecture is implemented in <samp>archures.c</samp>.

  101. </p>

  106. <p><strong>Description</strong><br>

  107. This enum gives the object file&rsquo;s CPU architecture, in a

  108. global sense&mdash;i.e., what processor family does it belong to?

  109. Another field indicates which processor within

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

  111. distinguishes different versions of the architecture,

  112. containing, for example, 68020 for Motorola 68020.
