Hi Michael,
Thanks I'll have another look at the regression tests today. We should be
enabling new tests now by supporting DWARF, but I don’t think my
last run with a microblaze-xilinx-linux-gnu was giving me as many
failures as you see;
=== g++ Summary ===
# of expected passes 26617
# of unexpected failures 17
# of unexpected successes 2
# of expected failures 167
# of unresolved testcases 3
# of unsupported tests 433
thanks,
David
