* If a SCC has a node without a function, then the SCCDuncan Sands2008-09-031-9/+14
| | | | | | | | | | | analysis would bail out without removing function records for other members of the SCC (which may exist if those functions read or wrote global variables). Since these are initialized to "readnone", this resulted in incorrect alias analysis results. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@55714 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | callgraph, when one member of a SCC calls another then the analysis would drop to mod-ref because there is (usually) no function info for the callee yet; fix this. Teach the analysis about function attributes, in particular the readonly attribute (which requires being careful about globals). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@55696 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | into alias analysis. This meant updating the API which now has versions of the getModRefBehavior, doesNotAccessMemory and onlyReadsMemory methods which take a callsite parameter. These should be used unless the callsite is not known, since in general they can do a better job than the versions that take a function. Also, users should no longer call the version of getModRefBehavior that takes both a function and a callsite. To reduce the chance of misuse it is now protected. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@44487 91177308-0d34-0410-b5e6-96231b3b80d8
