Hi,
after the merge of nvidia OpenMP implementation, the normal parallel
outline functions were also marked as "omp declare target" which lead
to them being cloned and compiled to HSA which is not only unnecessary
but often leads to a lot of useless HSA warning noise. The following
patch deal with this issue by making sure they are not considered
callable from HSA.
Bootstrapped and tested on x86_64-linux. I will commit it to trunk in
a few moments (it is already part of my most recent merge from trunk
to the hsa branch.
Thanks,
Martin
