endloopX jumps always jump to loopX start. Not to the value in the SA register.

[Rot127]

endloop instructions jump to the value in the SA0/SA1 register (if LC0/LC1 are greater than 0).

The values in SA0/SA1 can change during loop execution. Regardless of that, the jump targets of endloop instructions are always set to the original loop start. They will not change if the SA register is set again. This is technically incorrect.

We can't fix this because we can not emulate the code yet and it can't be detected during static analysis anyways.
So this will not be fixed but should be noted by anyone using this plugin.

This pattern often happens if multiple endloopX instructions belong to a single loopX instruction.

If you haven't done already you can check out the chapter about hardware loops in the programmers reference manual for a more in depth explanation of loop behavior.
