std::pair< unsigned, unsigned > GCNSubtarget::computeOccupancy	(	const Function &	F,

Subtarget's minimum/maximum occupancy, in number of waves per EU, that can be achieved when the only function running on a CU is F, each workgroup uses LDSSize bytes of LDS, and each wave uses NumSGPRs SGPRs and NumVGPRs VGPRs.

The flat workgroup sizes associated to the function are a range, so this returns a range as well.

Note that occupancy can be affected by the scratch allocation as well, but we do not have enough information to compute it.

◆ zeroesHigh16BitsOfDest()

bool GCNSubtarget::zeroesHigh16BitsOfDest ( unsigned Opcode ) const

Returns if the result of this instruction with a 16-bit result returned in a 32-bit register implicitly zeroes the high 16-bits, rather than preserve the original value.

This list was mostly derived from experimentation.
