================
Comment at: llvm/include/llvm/Transforms/IPO/FunctionSpecialization.h:51
+// To compute the codesize increase, we first estimate the initial codesize of
+// the function as [number of instructions] + [number of inline candidates] x
+// [small function size]. The "small function size" corresponds to the minimum
----------------
Thanks for adding these descriptions, that is very helpful.
Just trying to understand the initial code size calculation better, the last part:
[number of inline candidates] x [small function size]
why is that not the [number of instructions] for each inline candidate?
