[PATCH] D47655: [MachineOutliner] Don't outline sequences where x16/x17/nzcv are live across

Mon Jun 25 10:08:49 PDT 2018

paquette updated this revision to Diff 152716.
paquette added a comment.

Updated diff to actually fix the LRU stuff (oops).

Also updated the test because the change makes a couple (safe) cases that worked with the (wrong) fix no longer work. Added a comment explaining what's going on to the test to keep note of the fact that there are a few more cases we can probably catch.
