[flang-dev] F95 intrinsics status

[Jean Perier via flang-dev]

Hi Diana,

When the cells are empty, it means I did not check yet what was the runtime status for the intrinsic. If the related lowering cell is OK, then it means no runtime is needed to implement the intrinsic. Regarding ADJUSTL/ADJUSTR, lowering was not added yet, but you are right, the runtime is here. I have updated the spreadsheet to reflect this as well as other intrinsic for which there were recent changes (like DOT_PRODUCT). For F95, I think the missing runtime part is mainly the time related functions (CPU_TIME/SYSTEM_CLOCK).
OK in "Library status" does not mean it is thoroughly tested, so if you want to add a "Library unit tests" column and start gathering a status for this and adding more tests when needed, go for it, I think it will always be valuable.

To coordinate in live, I think we can start by using flang-compiler general slack channel [2], if the traffic regarding this topic turns out too big, we can always create an f18-intrinsics channel later.

Hello everyone,

I was looking at the intrinsic status spreadsheet that was shared in the call yesterday [1] and I'm a bit confused about some of the intrinsics. For instance, there's not much information about ADJUSTL / ADJUSTR, but as far as I can tell there already is some support for them in the runtime and also in folding (and I think I also recently saw support for DOT_PRODUCT landing in the runtime). Does this just mean that the spreadsheet isn't up to date, or is there some other requirement that isn't met (e.g., not enough tests)?

In any case, I'd like to help with this but I'm not entirely sure who I should be coordinating with. Should we maybe have a slack channel for this? Any pointers appreciated :)

Thanks,
Diana
