2012-12-21Don't eagerly emit a global static merged with a local extern.Rafael Espindola
When we are visiting the extern declaration of 'i' in static int i = 99; int foo() { extern int i; return i; } We should not try to handle it as if it was an function static. That is, we must consider the written storage class. Fixing this then exposes that the assert in EmitGlobalVarDeclLValue and the if leading to its call are not completely accurate. They were passing before because the second decl was marked as having external storage. I changed them to check the linkage, which I find easier to understand. Last but not least, there is something strange going on with cuda and opencl. My guess is that the linkage computation for these languages needs to be audited, but I didn't want to change that in this patch so I just updated the storage classes to keep the current behavior. Thanks to Reed Kotler for reporting this. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@170827 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-21[analyzer] Traverse the Call Graph in topological order.Anna Zaks
Modify the call graph by removing the parentless nodes. Instead all nodes are children of root to ensure they are all reachable. Remove the tracking of nodes that are "top level" or global. This information is not used and can be obtained from the Decls stored inside CallGraphNodes. Instead of existing ordering hacks, analyze the functions in topological order over the Call Graph. Together with the addition of devirtualizable ObjC message sends and blocks to the call graph, this gives around 6% performance improvement on several large ObjC benchmarks. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@170826 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-21[analyzer] Add blocks and ObjC messages to the call graph.Anna Zaks
This paves the road for constructing a better function dependency graph. If we analyze a function before the functions it calls and inlines, there is more opportunity for optimization. Note, we add call edges to the called methods that correspond to function definitions (declarations with bodies). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@170825 91177308-0d34-0410-b5e6-96231b3b80d8
