[flang-dev] [Classic flang] RFC: Adding release_110 branch to flang-compiler/classic-flang-llvm-project

Fri Jan 22 00:16:00 PST 2021

Hi Vinay,

Thanks a lot for taking time to check this and let us know!
The branch_11x was already pulled to the origin repo, just 15 minutes
before your e-mail.

Are the issues you mention a regression compared to branch_100 of
classic-flang-llvm-project? Do you know if f18 (
https://github.com/llvm/llvm-project/tree/release/11.x/flang) does any
better?

If these are important, perhaps you could report them as issues in the
github repository (
https://github.com/flang-compiler/classic-flang-llvm-project/issues)? I do
not have access to the SPEC benchmark and I think much of the community
might not have it, so it would be great if you could provide some minimal
reproducers.

I will try to determine if we have the bandwidth to work on them and let
you know by Monday.

Best regards,
