* Core mark benchmark and report for PGO and PGO + LTO (TCWG-544) (6/10)
Going by CPU cycles adding LTO gains in x86 and degrades in Aarch64 .

Looked at hot functions and examining assembly the code generation seems to be same. X86_64 does alignment of code. Also branch misses decreased in X86_64 compared to Aarch64 with -flto + -O3. 

  

Also profiled for instruction counts on Aarch64 with linaro compiler. These profiles say that we are executing less instructions with LTO and PGO for Aarch64. 

* PR 63173-  Reproduced the issue and changed the test case to work with trunk. Now Looks like someone else has a patch for it. (1/10).  so will work on other bugs.

* Misc [3/10]
   Internal work, emails, AMD meetings and 1-1 with inline manger.
   1-1 with Maxim, christophe and 1-1 with ryan

* Coremark benchmark and profiling.

Investigate trunk degradation  for O3+  PGO + LTO and report.
