[PATCH] D78659: Add nomerge function attribute to supress tail merge optimization in simplifyCFG

[Roman Lebedev via Phabricator via cfe-commits]

lebedev.ri added inline comments.


================
Comment at: llvm/include/llvm/IR/Attributes.td:106
 
+/// Disable tail merge for this function
+def NoMerge : EnumAttr<"nomerge">;
----------------
Elsewhere we seem to be preventing any kind of movement,
not just disabling inlining of such functions if the call is a tailcall.
