The copy propagation algorithm is very simple at the moment and can only
handle COPY instructions (it calls MachineInstr::isCopy to check if an
instruction is a "copy"). It could easily be extended (via target
hooks) to recognize more advanced examples (such as reg+imm(0), for
example, or "combine" instructions in case of Hexagon). It also does
not update the DFG, which is the biggest issue right no...

[LLVMdev] Usability of phabricator review threads for non-phab-users
Alp noted that the current setup on how phab reviews land on the list are

whether there are more widespread problems. If this is more widely
perceived as a problem, please speak up, and I'll make sure to prioritize
the fixes (note that this is unrelated to the "lost email" problem - those
