[LLVMdev] Inlining in LLVM

[J Nelson Amaral]

Duncan:

I am only superficially familiar with LLVM structure.

What I am trying to find out is if functions that have a single invocation
are still found in the code during the compilation.

In Open64 and other compilers, there is an early inlining pass that inlines
all procedures that have a single invocation site. The reasoning is that if
there is a single call to a procedure, then there is not downside to
inlining it.

Does LLVM usually does that? Or would that be left to whatever front-end is
being used?
