Most of Last week spent on internal AMD work.

== Progress == * AArch64 LTO and PGO support. LTO run for coremark and ran coremark on V8 model with and without the patch. Ran perf on the model against the both the coremark binaries. For non LTO, retired instructions seems to be less than the LTO one. And PGO run for coremark did not emit any gcda file. Need to drill down further.

* AAarch64 testing GCC runs still on going. Experimenting on spawning subtarget tests to more than one V8 model.

== Plan == * Complete gcc testsuite with runs with trunk and trunk+gprof GCC patches. * Continue LTO and PGO runs for AArch64

==issues== * libssp support for AArch64 This work is currently in hold. Needed frame layout changes before restarting.
