=== Work done during this week ===

* Continue work on TCWG-1428 (Support arithmetic on FileCheck regex variable): external review + finish adding comments + add documentation and testcase + respond to feedback and send email to llvm-dev to discuss best syntax for new feature * Started looking into TCWG-1062 (MCF branch prediction overload due to too many consecutive branches): + figure out what machines to run spec on, where to find spec and how to use Linaro scripts to install/configure and run it (thanks to Christophe Lyon) + try to build a native clang toolchain but throw it away since clang does not link (perhaps due to lack of memory (4G machine)) + learn how to build a cross LLVM toolchain (thanks to Peter Smith) + figure out how to get the right privilege to run perf (thanks to Christophe Lyon) * Misc: + LLVM buildbot babysitting with Peter Smith + attend presentation about Windows on Arm + start a full reorganization of my workflow + finish handover of my Arm tickets

=== Plan for week 28 ===

* DSGHACK-25 (Support arithmetic on FileCheck regex variable): address comments + rework patch once syntax is agreed * Continue looking into MCF branch prediction overload due to too many consecutive branches: + reproduce/confirm issue + start to investigate a solution
