Cleanup GlobalsModRef a bit. When analysing the 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 2008-09-03 12:55:42 +00:00
Modify the LLVM assembly output so that it uses references to represent function attributes. This makes the LLVM assembly look better. E.g.: define void @foo() #0 { ret void } attributes #0 = { nounwind noinline ssp } git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175605 91177308-0d34-0410-b5e6-96231b3b80d8 2013-02-20 07:21:42 +00:00			`; CHECK: define i32 @f() #0`
