/*** Load Linked and Store Conditional logic ***
A 32-bit register keeps track of the address for atomic Load Linked / Store Conditional
operations. This register can be updated during stalls since it is not visible to
forward stages. It does not need to be flushed during exceptions, since ERET destroys
the atomicity condition and there are no detrimental effects in an exception handler.
The atomic condition is set with a Load Linked instruction, and cleared on an ERET
instruction or when any store instruction writes to one or more bytes covered by
the word address register. It does not update on a stall condition.
The MIPS32 spec states that an ERET instruction between LL and SC will cause the
atomicity condition to fail. This implementation uses the ERET signal from the ID
stage, which means instruction sequences such as "LL SC" could appear to have an
ERET instruction between them even though they don't. One way to fix this is to pass
the ERET signal through the pipeline to the MEM stage. However, because of the nature
of LL/SC operations (they occur in a loop which checks the result at each iteration),
an ERET will normally never be inserted into the pipeline programmatically until the
LL/SC sequence has completed (exceptions such as interrupts can still cause ERET, but
they can still cause them in the LL SC sequence as well). In other words, by not passing
ERET through the pipeline, the only possible effect is a performance penalty. Also this
may be irrelevant since currently ERET stalls for forward stages which can cause exceptions,
which includes LL and SC.
