fixed_offset
Represent an integer based offset whose
value specified at compile time.
#include
<sdlt/fixed_offset.h>
Syntax
template <int OffsetT> fixed_offset;
Arguments
- int OffsetT
- The value the fixed_offset will represent
Description
fixed_offset is a deprecated feature.
If we can tell the compiler that we know an offset at compile time, then
when combined with a loop index inside a SIMD loop, the compiler can use that
information to maintain aligned access (should the offset be aligned) when
accessing underlying data layout. When multiple accesses are happening near
each other, the compiler will have the opportunity to detect which accesses
occur in the same cache lines and potentially avoid prefetching the same cache
line repeatedly. Whenever possible, a fixed_offset should be used over an
aligned_offset or integer based offset.
