pseudoInstWork()

template<typename ABI , bool store_ret>

bool gem5::pseudo_inst::pseudoInstWork	(	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.
