<br>
For atomic_ops.c, it seems that the test just needs to ignore or XFAIL<br>
for this target since the test just assumes all targets (except for<br>
hexagon and sparc) will have native atomic load support (ie load<br>
atomic vs call void @__atomic_load).<br>
<br>
For illegal-UTF8.m, I don't know objective C very well, but I think<br>
it's a similar issue where there is an unsupported feature for this<br>
target and it should be ignored/XFAIL'd also.<br>
<br>
And for the go test, I don't know what that is or why it's broken :p.<br>
