[ppc64] ICE building libupc #52

Closed PHHargrove closed 10 years ago

PHHargrove commented 10 years ago

Today's latest code doesn't build on Linux/ppc64. This is the first time I've tried in quite a while.

I am seeing an internal compiler error from the just-built clang when it is trying to compile upc_barrier.upc in the smp runtime.

[ 95%] Built target upc-link-script

Fix in 358cae7 worked for me. Thanks, Nenad.
