Available on (x86 or x86-64) and target feature
sse
and x86 only.Expand description
Stores the lowest 32 bit float of a
repeated four times into aligned
memory.
If the pointer is not aligned to a 128-bit boundary (16 bytes) a general protection fault will be triggered (fatal program crash).
Functionally equivalent to the following code sequence (assuming p
satisfies the alignment restrictions):
let x = a.extract(0);
*p = x;
*p.add(1) = x;
*p.add(2) = x;
*p.add(3) = x;
