vec_xst_len
Purpose
Stores a given byte length of a vector to a given address.
Note: This built-in function
is valid only when both of the following conditions are met:
- The -mcpu option is set to target POWER9 processors or higher.
- The compiler mode is 64-bit.
Syntax
void vec_xst_len(a, b, c)Argument types
The following table describes the types of the function arguments.
| a | b | c |
|---|---|---|
| vector signed char | signed char * | size_t |
| vector unsigned char | unsigned char * | size_t |
| vector signed short | signed short * | size_t |
| vector unsigned short | unsigned short * | size_t |
| vector signed int | signed int * | size_t |
| vector unsigned int | unsigned int * | size_t |
| vector signed long long | signed long long * | size_t |
| vector unsigned long long | unsigned long long * | size_t |
| vector float | float * | size_t |
| vector double | double * | size_t |
Result
No value is returned. The specified bytes of a are stored into an address. The number of bytes to be stored is specified
by c and the address is
specified by b.
The behavior is undefined if the value of c is outside of 0-255. The behavior is implementation defined if the value
of c is not a multiple of
the vector element size.
