update flang to 11.0.1

[xoviat]

Also, use stock clangdev, llvmdev, and remove flang-meta package.

Hi! This is the friendly automated conda-forge-linting service.

I just wanted to let you know that I linted all conda-recipes in your PR (recipe) and found it was in an excellent condition.

I do have some suggestions for making it better though...

@conda-forge-admin Please rerender.

@isuruf a little help? https://dev.azure.com/conda-forge/feedstock-builds/_build/results?buildId=269656&view=logs&j=a70f640f-cc53-5cd3-6cdc-236a1aa90802&t=f5d15007-a01c-5ad8-c9ce-4d519d3b275f&l=107083

The current scheme creates a new environment, which seems to break the ninja paths.

@isuruf cmake appears to install to "build env" rather than "h env". I tried to fix it, but failed.

[isuruf]

Can you revert to 6c280b5 ? That run failed because llvmdev 11 is not patched to produce a flang.exe.

[xoviat]

@isuruf That's not correct. I reconfigured flang so that it doesn't require a patched clang or llvm. See https://dev.azure.com/conda-forge/feedstock-builds/_build/results?buildId=269696&view=logs&j=a70f640f-cc53-5cd3-6cdc-236a1aa90802&t=f5d15007-a01c-5ad8-c9ce-4d519d3b275f&l=107152, (scroll down to 107180).

That build failed because it copied the files to build_env

[xoviat]

Note: it shouldn't be too difficult to get linux working with this as well, but I don't have a linux box and I'm currently too lazy to install wsl.

[xoviat]

@isuruf before you merge this, I have some minor fixes, so I'd like to update the commit. Let me know if you're okay with this first.

[xoviat]

[xoviat]

anything else?

[xoviat]

Wait libflang needs pgmath as well, maybe

[xoviat]

@isuruf This looks good.

[xoviat]

@isuruf I went ahead an confirmed that this works on OpenBLAS with enhanced testing (OpenMathLib/OpenBLAS#3088).

[isuruf]

Is flang.dll that this produce compatible with the older flang.dll?

[xoviat]

I can say with complete certainty that the flang.dll that this produces is ABI-compatible with the DLL from the official flang project (if one were to be generated). The official flang project extracted some of the math functionality into a new "pgmath.dll" library. This is not a change that I made; I simply have as few changes as possible with the official flang project, while fixing any major bugs.

[xoviat]

see flang-compiler/flang@7a601b0#diff-9ce46d50a39e8b38c4ffebdeebfc08c3f1c7b8c3440cb7efada77fbb1b484829

[xoviat]

I think it would be nice to have a new flang though, because right now the clang version is stuck at 5, and flang is the only fortran compiler in conda-forge for windows.

[xoviat]

@isuruf Is there anything else?

[isuruf]

Thanks
