# 1.27.0[−][src]Function core::arch::x86::_mm_store1_ps

    pub unsafe fn _mm_store1_ps(p: *mut f32, a: __m128)

This is supported on x86 and target feature `sse` only.

Store 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.offset(1) = x;
    *p.offset(2) = x;
    *p.offset(3) = x;

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)

Search multiple things at once by splitting your query with comma (e.g. `str,u8` or `String,struct:Vec,test`)
