Hi 陳韋任,

Sorry for the late response.

I'm not particularly happy about the failures here. We need to get to the
bottom of them. In the previous email, you tried setting CFLAGS and CXXFLAGS to
-fno-strict-aliasing during configuration. Try setting them during the
'make' command:

	$ make ... CFLAGS=-fno-strict-aliasing CXXFLAGS=-fno-strict-aliasing

etc.

If you get failures with that, then try one of the test cases and see how
it's failing. If it's a crash, then see if you can figure out why
it's crashing. :-) You may have to compile and run things by hand to really
dig into this...

  As you can see, the result of cross and native compile is quit different.
Although currently I do both, I think we should decide we should count on
cross or native compile result. Any suggestion on which one I should look into?

  Status update:

  With "CFLAGS=-fno-strict-aliasing CXXFLAGS=-fno-strict-aliasing",
the cross
build still has the same failures before.

Hi Bill,

  James told me that regression tests aren't really set up to run cross.
Maybe that's why cross build has more failures than native build. Anyone
can help to confirm this?

Hi Bill,

  I forgot to do Phase2/Phase3 build. Here is the Phase3 regression test
result,

  http://people.cs.nctu.edu.tw/~chenwj/tmp/phase3-regression-test.txt

Most LLVM failures are gone. As for ExecutionEngine, I guess ARM JIT is
not at a good shape at this moment, right? Perhaps we should focus on Clang
failures?

Hi chenwj,

Thanks for the report. Yeah, it's probably best to track down what's
happening with clang. Could you investigate this further?
