[PATCH] D68633: fix debug info affects output when opt inline

[Bjorn Pettersson via Phabricator via llvm-commits]

I do not understand how this helps. The code is written in a way that it skips any instruction, but moves contigous blocks of allocas in one splice (not sure exactly why, is that really faster?). Maybe the difference is that the check for AI->useEmpty() only is done for the first alloca in a sequence of alloca instructions? Or can't we just remove the loop at line 1847 (only moving one alloca at a time).
