[PATCH] D50286: avoid creating conditional cleanup blocks that contain only @llvm.lifetime.end calls

[John McCall via Phabricator via cfe-commits]

rjmccall added inline comments.


================
Comment at: lib/CodeGen/CGExpr.cpp:521
+          CGM.getCodeGenOpts().OptimizationLevel > 0 &&
+          !CGM.getCodeGenOpts().SanitizeAddressUseAfterScope) {
+        OldConditional = OutermostConditional;
----------------
Why only when optimization is enabled?  This seems like a nice improvement 
regardless.

Also, please mention why this is disabled for destructed types in the comment, 
not just the commit message.
