[PATCH] D86812: [DebugInstrRef][1/3] Track PHI values through register allocation

[Jeremy Morse via Phabricator via llvm-commits]

jmorse updated this revision to Diff 290943.
jmorse added a comment.

Address comments; add a test for creating DBG_PHIs for PHIs that happen in spill slots.

(I also suggested a test was needed for sub-register inputs; however on further examination, you can't PHI unequal register classes, so subregisters don't enter the picture at that stage).
