When I tried to use tryTrack()
in PHINode::setIncomingValue()
I realized that PHISetIncoming
's constructor was taking a copy of the the instruction, rather than a reference, which would cause a crash when reverting. So I disabled copies here and I also reverted back to the original tracking code for setIncomingValue()
. I will address those in a separate patch.

hmm, at a first glance this seems a bit too magical, it's not clear that tryTrack
is basically make_unique
. it's hard to suggest something that isn't so magical though...
True. We could perhaps rename it to something like |
I would call it |
Renamed |
bool emplaceIfTracking(ArgsT... ChangeArgs) { | ||
if (!isTracking()) | ||
return false; | ||
track(std::make_unique<ChangeT>(ChangeArgs..., *this)); |

I'm not a fan of the implicit Tracker
argument at the end, it's very not obvious. I'd make the caller pass it in. (It looks like most tracker objects don't actually need it aside from debugging purposes)

An alternative would be to remove the Tracer argument from the constructors and set the parent within track(). This is not as ugly as it seems at first glance because the change objects are only created within the track() function. And btw their constructors should be made private since the user won't create these objects directly.
Wdyt?

@aeubanks I removed the Parent
member variable from IRChangeBase
. Instead I am passing it to revert(Tracker &)
because it was used by EraseFromParent::revert()
.
How do you like this version?

ah very interesting, I like this a lot!
This patch introduces Tracker::emplaceIfTracking(), a wrapper of Tracker::track() that will conditionally create the change object if tracking is enabled. This patch also removes the `Parent` member field of `IRChangeBase`.
