pseudoInst()

template<typename ABI >

bool PseudoInst::pseudoInst	(	ThreadContext *	tc,
		uint8_t	func,
		uint64_t &	result
	)

Execute a decoded M5 pseudo instruction.

The ISA-specific code is responsible to decode the pseudo inst function number and subfunction number. After that has been done, the rest of the instruction can be implemented in an ISA-agnostic manner using the ISA-specific getArguments functions.

Parameters

func	M5 pseudo op major function number (see utility/m5/m5ops.h)
result	A reference to a uint64_t to store a result in.

Returns

Whether the pseudo instruction was recognized/handled.
