davezarzycki added a comment to D94656: [libcxx testing] Fix UB in tests for std::lock_guard.

I appreciate that you're trying to make this be defined behavior, but I honestly don't know why this is UB. I can't think of or find a platform where the underlying OS "trylock" routine would have UB when called on the same thread that owns the lock already. Can somebody with access to the C++ standard provide any hint to why the standard wants this to be UB?

The test is just broken. Tests are not allowed to modify the source as they run. I'm sorry but I need to revert this. If you need help testing on a read-only source checkout, please let me know.

davezarzycki added a comment to D91488: Consider reference, pointer, and pointer-to-membber TemplateArguments to be different if they have different types..

Thanks. I just verified that reverting this change fixes the second stage regression and was about to commit the revert.

This change is causing second stage build failures on Fedora 33 (x86-64). I'll probably revert this soon, but in the mean time, here is a snippet of the build output:

Hi @spatel – We can certainly remove the code gen tests that should have been handled by earlier optimization passes. Thanks for working on those. :-)

As to the use case, I have AVX512 machines without BITALG/VPOPCNTDQ and a program that is doing hamming distance checks in critical sections. I.e. lots of low numbered "popcnt(x) < smallNumber" kind of checks that would be more efficiently implemented as a chain of legal "x & (x - 1)" instructions instead of the current/custom POPCNT emulation logic. This is especially true on my Knights Landing test box, which lacks AVX512BW and falling back to AVX2 to emulate VPOPCNTDQ is quite expensive.

Ok - I have no doubts that there are cases we can optimize better. It would be great to see 1 or more reduced examples of these code patterns in source code. That way, we can confirm that we're not still missing any pre-codegen optimizations . Can you file a bug to show that?

Updated CTPOP emulation cost heuristics and test diffs so people can see the fallout. Overall, I tried to aim for the same or fewer number of instructions as before, which should be a win because chains of "x & (x - 1)" don't require memory loads, unlike actual CTPOP emulation.

davezarzycki added a comment to D86354: [ADT] Make Optional a literal type..

This seems to only allow empty optionals to be constexpr. Should the non-default constructor also be constexpr?

The reason I implemented the minimal thing was that I wasn't sure how far I should go. In a Swift PR, @davezarzycki raised the point about constexpr potentially leading to longer compile times even when not used for compile-time computation. I asked some folks internally at Apple and the response I got was along the lines of, "That's surprising... If that's actually the case, it should be reported as a Clang bug". I haven't been able to dedicate time to benchmarking the impact of constexpr on compile time... Since Optional is a currency type, I wasn't sure if people would object to more methods being marked constexpr. In principle, I don't see any reason for any method on Optional to not be constexpr.

That upstream thread doesn't look like it's talking about the impact of constexpr in non-constexpr contexts. Yes, making a variable constexpr when you don't need it to be can have negative compile time consequences - but in Clang I don't believe (again, can be bugs, but it doesn't sound like that swift thread is suggesting the existence of such bugs) a constexpr function called in a non-constexpr context is handled any differently than if it were a non-constexpr function. (GCC is different in this regard and does try to do constexpr things in non-constexpr contexts, though unclear how hard it tries before bailing out to the non-constexpr handling)
