Member Function Documentation

areDenormalsDisabled()

bool JUCE_CALLTYPE juce::FloatVectorOperations::areDenormalsDisabled ( )

staticnoexcept

This method returns true if denormals are currently disabled.

convertFixedToFloat() [1/2]

void JUCE_CALLTYPE juce::FloatVectorOperations::convertFixedToFloat ( float * dest, const int * src, float multiplier, int num )

staticnoexcept

convertFixedToFloat() [2/2]

void JUCE_CALLTYPE juce::FloatVectorOperations::convertFixedToFloat ( float * dest, const int * src, float multiplier, size_t num )

staticnoexcept

disableDenormalisedNumberSupport()

void JUCE_CALLTYPE juce::FloatVectorOperations::disableDenormalisedNumberSupport ( bool shouldDisable = true )

staticnoexcept

On Intel CPUs, this method enables the SSE flush-to-zero and denormalised-are-zero modes. This effectively sets the DAZ and FZ bits of the MXCSR register. On arm CPUs this will enable flush to zero mode. It's a convenient thing to call before audio processing code where you really want to avoid denormalisation performance hits.

enableFlushToZeroMode()

void JUCE_CALLTYPE juce::FloatVectorOperations::enableFlushToZeroMode ( bool shouldEnable )

staticnoexcept

This method enables or disables the SSE/NEON flush-to-zero mode.

getFpStatusRegister()

intptr_t JUCE_CALLTYPE juce::FloatVectorOperations::getFpStatusRegister ( )

staticprivatenoexcept

setFpStatusRegister()

void JUCE_CALLTYPE juce::FloatVectorOperations::setFpStatusRegister ( intptr_t fpsr )

staticprivatenoexcept
