   <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 but these are generally not recommended for most uses.</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.  aapcs-linux is recommended over
-  aapcs.</para>
-
-  <para os="c">The OABI (old ABI) is called apcs-gnu and supports ARMv4 and 
-  older cores.  Generally the OABI is not used by modern ARM processors.</para>
+  <para os="b">The EABI (Embedded ABI) is the recommended ABI to use for ARM.
+  The EABI has sub-ABIs of: aapcs-linux and aapcs.  aapcs-linux has standard
+  Linux 4 byte enums and thus is recommended.  EABI supports armv4t and newer
+  processors.</para>
