using CpuFeatures::BitWord = Support::BitWord[¶]
A word that is used to represents feature bits.
using CpuFeatures::Iterator = Support::BitVectorIterator<BitWord>[¶]
Iterator that can iterate all CPU features set.
bool CpuFeatures::is_empty() constnoexcept[¶]
Returns true if there are no features set.
template<typename T = Data>T& CpuFeatures::data()noexcept[1/2][¶]
Casts this base class into a derived type T.
template<typename T = Data>const T& CpuFeatures::data() constnoexcept[2/2][¶]
Casts this base class into a derived type T (const).
X86& CpuFeatures::x86()noexcept[1/2][¶]
Returns CpuFeatures::Data as CpuFeatures::X86.
const X86& CpuFeatures::x86() constnoexcept[2/2][¶]
Returns CpuFeatures::Data as CpuFeatures::X86 (const).
ARM& CpuFeatures::arm()noexcept[1/2][¶]
Returns CpuFeatures::Data as CpuFeatures::ARM.
const ARM& CpuFeatures::arm() constnoexcept[2/2][¶]
Returns CpuFeatures::Data as CpuFeatures::ARM (const).
BitWord* CpuFeatures::bits()noexcept[1/2][¶]
Returns all features as array of bitwords (see Support::BitWord).
const BitWord* CpuFeatures::bits() constnoexcept[2/2][¶]
Returns all features as array of bitwords (const).
size_t CpuFeatures::bit_word_count() constnoexcept[¶]
Returns the number of BitWords returned by bits().
Iterator CpuFeatures::iterator() constnoexcept[¶]
Returns Support::BitVectorIterator, that can be used to iterate over all features efficiently.
template<typename FeatureId>bool CpuFeatures::has(const FeatureId& feature_id) constnoexcept[¶]
Tests whether the feature feature_id is present.
template<typename... Args>bool CpuFeatures::has_any(Args&&... args) constnoexcept[¶]
Tests whether any of the features is present.
bool CpuFeatures::has_all() constnoexcept[¶]
Tests whether all features as defined by other are present.
void CpuFeatures::reset()noexcept[¶]
Clears all features set.
template<typename... Args>void CpuFeatures::add(Args&&... args)noexcept[¶]
Adds the given CPU feature_id to the list of features.
template<typename... Args>void CpuFeatures::add_if(bool condition, Args&&... args)noexcept[¶]
Adds the given CPU feature_id to the list of features if condition is true.
template<typename... Args>void CpuFeatures::remove(Args&&... args)noexcept[¶]
Removes the given CPU feature_id from the list of features.
bool CpuFeatures::equals() constnoexcept[¶]
Tests whether this CPU features matches other.
