Well, I did run EV4 testing with real hardware recently. As an example
here's the summary of results for the C frontend only:
=== gcc Summary ===
# of expected passes 149119
# of unexpected failures 134
# of expected failures 1117
# of unresolved testcases 3
# of unsupported tests 3176
(I ran testing across the board). If non-BWX is known to be broken with
LRA, then perhaps let's only make the switch for BWX for the time being?
