unresolved external symbols when building OpenBLAS with OpenMP and DYNAMIC arch

[xoviat]

unknown where these symbols may originate from, or if they should have been generated.

Those symbols are the parallel routines from the parallel regions starting at line *_F1L<NUMBER>_1_

[xoviat]

Are they defined in the runtime somewhere?

[d-parks]

They should be defined in the corresponding .obj file (for example I'd expect _nv_zhetrd_hb2st__F1L467_1 to be defined in zhetrd_hb2st.F.obj)

Do you have flang installed on linux? Can you give me the ILM and IR files for https://github.com/xianyi/OpenBLAS/blob/develop/lapack-netlib/SRC/ssytrd_sb2st.F so that I can compare them to mine?

Here's my ILM file: https://gist.github.com/xoviat/7f365836c4984d1ce3338d5f64efa016
