[aarch64-port-dev ] Errors in aarch64 C1 caught by the Mauve test suite

[Andy Johnson]

I have been running the Mauve test suite on openembedded using the ARM
Foundation_v8 model and the aarch64 port of OpenJDK8.  With a few
exceptions, the results from running the template interpreter (-Xint) match
those from the baseline xi6-64 OpenJDK8 port.  However, I am getting a
number of failures using -Xcomp (C! compiler) that I don't get using
-Xint.  I am excluding test failures that are generic to Mauve (i.e. they
fail on all OpenJDK8 ports, including x86-64).

the x86-64 baseline]

For each of the SIGSEGV errors, I have the corresponding hs_err_pidxxxx.log
files, which I can provide or post as needed.

I am also seeing a large discrepancy between -Xint and -Xcomp on both the
java.awt tests (73 additional failures) and the javax.swing tests (32
additional failures).  I will be filing a more detailed report on these
later.
