<title>Errata</title>
<para>The following sections of version 1.0 of the POWER Vector Intrinsics
Programming Reference are modified as specified.</para>
<section>
  <title>Section 4.2, Built-In Vector Functions</title>
  <para>
    <emphasis role="underline">Problem</emphasis>: For intrinsics that
    represent vector load and store operations, the arguments that
    represent offsets from a pointer are listed as having type "signed
    long long."  Although this is correct for 64-bit code, and this is
    a 64-bit specification, it is recognized that this is not
    compatible with existing 32-bit implementations.  This can be
    resolved using the type "signed long" instead, which is 64 bits on
    a 64-bit system and 32 bits on a 32-bit system.
