Hi Jakub,
So, either we'd need to add e.g. preprocessing support for gfortran.map or some other way how to make certain symbols appear conditionally at different symbol versions, or another option would be to choose different symbol names for those for the powerpc64le-linux cases (e.g._gfortran_transfer_{real,complex}ieee128{,_write}). Any preferences?
My personal preference would be the ieee128 variant, it would be cleaner that way, but I have no strong opinion either way. So, that variant is OK from my side, but maybe you could wait for a day or so for anybody else to chime in. Best regards Thomas
