Detailed Description

Checks if endianess was detected correctly at compile-time.

Returns

True if endianess defined in GAIA_LITTLE_ENDIAN/GAIA_END_ENDIAN is correct. False otherwise.

Warning

If false is returned, flip the values in GAIA_LITTLE_ENDIAN and GAIA_BIG_ENDIAN.

Enumeration Type Documentation

PrefetchHint

enum gaia::PrefetchHint : int

Enumerator
PREFETCH_HINT_T0	Temporal data — prefetch data into all levels of the cache hierarchy.
PREFETCH_HINT_T1	Temporal data with respect to first level cache misses — prefetch data into L2 cache and higher.
PREFETCH_HINT_T2	Temporal data with respect to second level cache misses — prefetch data into L3 cache and higher, or an implementation-specific choice.
PREFETCH_HINT_NTA	Non-temporal data with respect to all cache levels — prefetch data into non-temporal cache structure and into a location close to the processor, minimizing cache pollution.
