Hi Bin,
No, that's a mistake on my part -- thanks for the report! That first
added line was not intended to be part of the patch:
+/* vect_hw_misalign && { ! vect64 } */
Please try removing that line and verify that the patch succeeds again
for ARM. Assuming so, I'll prepare a patch to fix this.
It looks like this mistake was introduced only in this particular test,
but please let me know if you see any other anomalies.
Thanks very much!
Bill
