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

Fri Jan 22 01:45:28 PST 2021

Hi Michal,

I have created an issue (
https://github.com/flang-compiler/classic-flang-llvm-project/issues/11 )
with a test case.

> Are the issues you mention a regression compared to branch_100 of
classic-flang-llvm-project?
Do you mean
https://github.com/flang-compiler/classic-flang-llvm-project/tree/release_100 ?
It was working fine for this branch.

>  Do you know if f18 (
https://github.com/llvm/llvm-project/tree/release/11.x/flang) does any
better?
I haven't checked.

Thanks,
Vinay
