◆ 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
funcM5 pseudo op major function number (see utility/m5/m5ops.h)
resultA reference to a uint64_t to store a result in.
Returns
Whether the pseudo instruction was recognized/handled.
