From 9ad1cb59deda265441c1614fee5ec7f7dea7625d Mon Sep 17 00:00:00 2001 From: Nick Lewycky Date: Mon, 3 Jan 2011 03:19:35 +0000 Subject: Add spliceFunction to the CallGraph interface. This allows users to efficiently update a callGraph when performing the common operation of splicing the body to a new function and updating all callers (such as via RAUW). No users yet, though this is intended for DeadArgumentElimination as part of PR8887. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@122728 91177308-0d34-0410-b5e6-96231b3b80d8 --- include/llvm/Analysis/CallGraph.h | 11 ++++++++++- 1 file changed, 10 insertions(+), 1 deletion(-) (limited to 'include/llvm/Analysis/CallGraph.h') diff --git a/include/llvm/Analysis/CallGraph.h b/include/llvm/Analysis/CallGraph.h index 9dfe89416a..089f322e4a 100644 --- a/include/llvm/Analysis/CallGraph.h +++ b/include/llvm/Analysis/CallGraph.h @@ -138,6 +138,13 @@ public: /// not already exist.
