   <title>ABI Variables</title>
 
+  <para os="a">On the ARM architecture, there are two major ABI types to choose
+  from: EABI and OABI.  There is also a Thumb ABI and an Intel IWMMX specific
+  ABI.</para>
+
+  <para os="b">The EABI (Embedded ABI) is newer and supports additional
+  features, faster software floating point operations, and Thumb interworking,
+  but is only compatible with ARMv4t and newer cores.  The EABI has
+  sub-ABIs of: aapcs-linux and aapcs.  aapcs-linux has standard Linux 4 byte
+  enums while aapcs has variable length enums.</para>
+
+  <para os="c">The OABI (old ABI) is called apcs-gnu and supports ARMv4 and 
+  older cores.</para>
