/* This header files provides an abstraction for the various implementations
|
38 |
|
|
* of vector literal construction. The two formats are:
|
39 |
|
|
*
|
40 |
|
|
* 1) Altivec styled using parenthesis
|
41 |
|
|
* 2) C grammer friendly styled using curly braces
|
42 |
|
|
*
|
43 |
|
|
* The macro, VEC_LITERAL has been developed to provide some portability
|
44 |
|
|
* in these two styles. To achieve true portability, user must specify all
|
45 |
|
|
* elements of the vector being initialized. A single element can be provided
|
46 |
|
|
* but only the first element guarenteed across both construction styles.
|
47 |
|
|
*
|
48 |
|
|
* The VEC_SPLAT_* macros have been provided for portability of vector literal
|
49 |
|
|
* construction when all the elements of the vector contain the same value.
