[llvm-dev] Understanding CallInst::Create

[Arnamoy Bhattacharyya via llvm-dev]

Hello;

I am working on porting a tool written for LLVM3.5 to LLVM10.  There
used to be a call instruction with the signature
static CallInst * Create (Value *F, Value *Actual, const Twine
&NameStr="", Instruction *InsertBefore=0)

Can anyone please explain what it supposed to do?  What was F and Actual?

Thank you so much.
