Hi! I committed the following in r221362:
commit 5121139d0e8b22290fc9e752b07752d8a1b70182
Author: tschwinge <tschwinge@138bc75d-0d04-0410-961f-82ee72b054a4>
Date: Wed Mar 11 21:42:50 2015 +0000
No libstdc++ for nvptx.
The C++ front end insists to link against libstdc++ -- which we don't build:
$ < build-gcc/gcc/testsuite/g++/g++.log grep -o 'error opening
[^[:cntrl:]]*' | sort | uniq -c
2 error opening libasan.a
2 error opening libssp.a
12075 error opening libstdc++.a
Based on GCC trunk r220892:
=== g++ Summary ===
