<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.
