=== Work done during this 4day week ===

* Continued looking into MCF branch prediction overload due to too
many consecutive branches:
  + managed to get reproducible results
    -> was missing --buildid-dir option when invoking perf
    -> above flag seems ignored if a binary with same path exists
where the initial binary was built
  + rerun again sampling only one event to confirm I get # of samples
* sampling freq = run time
  -> conclusion: LLVM as good as GCC for SPEC2006 MCF, profile
different because LLVM inlines one of the hot functions
* GCC PR85434 / CVE-2018-12886: upstream review
+  finish testing and submit for external review
* LLVM PR34170:
  + address comments and commit once approved
     -> most build bot failed to run the test the commit added, got
reverted before I could
  + investigate test failure -> does not fail when LLVM compiled with
GCC or in Debug mode
* Continue work on DSGHACK-25 (Support arithmetic on FileCheck regex variable):
  + hammer out syntax based on upstream feedback about what would be
desirable as FileCheck expressions
* Misc:
  + Linaro LLVM buildbot babysitting
  + upstream code review
* One day off on Friday



=== Plan for week 31 ===

* TCWG-1428 (Support arithmetic on FileCheck regex variable): address comments
  + rework patch once syntax is agreed
* Track down what causes testcase added for patch 2/3 for LLVM PR34170
* Try to reproduce perf issue mentioned above on latest perf
