Building on Issue#61, this merge request proposes to add configurable cache-replacement policies to Olympia.

@govardhnn Can you add the missing files that are preventing CI from running?

[govardhnn]

Will fix this by the Monday(Jan 20) TG meeting. Apologies for the delayed response!

Hi, I have borrowed the missing cache/ files from Sparta, which I implicitly assumed would be picked up form Map for the includes.
Not sure if this is right, but the regress target works in the release/ directory locally

• make -j4 regress

  100% tests passed, 0 tests failed out of 102
  
  Total Test time (real) =  40.33 sec
  [100%] Built target regress

You are correct that the missing cache files should be picked up from the sparta install. I cloned your branch locally, removed the core/cache directory and olympia built cleanly for me.

Yep @knute-mips, I'll try to replicate the same commands from Ubuntu-Release-gcc to see if the issue is in the CI.
Meanwhile let me also look into other areas to contribute in Olympia.

@knute-mips looks like the Branch-Pedictor test BranchPred_test_Run seg-faulted. Can you please rerun the CI tests?
I could not join the meeting today, apologies.

99% tests passed, 1 tests failed out of 109

Total Test time (real) =  80.96 sec
