You're right. I thought this test was *unintentionally* testing the case where
we have two hardware watchpoint register watching the same doubleword of
memory. But that was actually the point of the test (v.
https://reviews.llvm.org/D77173 ). I'm not sure how thrilled I am about this
test, it seems to be encoding the behavior of the cpu with multiple watchpoint
registers on the same doubleword and I don't know how universal that is - if a
CPU might only evaluate the first watchpoint on a doubleword and ignore the
second.
This is very much in the wheelhouse of the work I need to do on large
watchpoints where a single WatchpointResource should be used for both
watchpoints, expanded to include the byte range of both, and then reduced back
down again when one is disabled or deleted. I'll be adding tests like this one
as part of that work. I'll revert my change here.
