Hello all:
After fix one qemu issue about floating point insns, correct the related
environments (make some symbol links), and reconfig building options (so
support g++), the current gcc testsuite result are:
=== gcc Summary ===
# of expected passes 78156
# of unexpected failures 98
# of unexpected successes 1
# of expected failures 120
# of unresolved testcases 1
# of unsupported tests 1384
=== g++ Summary ===
# of expected passes 83999
# of unexpected failures 78
# of unexpected successes 2
# of expected failures 277
# of unsupported tests 3568
