[LLVMdev] globals in DS graph
I have some questions regarding how globals are represented in DS graph.
Specifically, I wrote the following simple program:
List *g;
void alloc_func(){
g = ( List* ) malloc( sizeof( List ) );
}
void free_func(){
free( g );
}
int main(){
alloc_func();
free_func();
}
I noticed that the DSnode for g in alloc_func is different from that of
free_func and NEITHER of them had GlobalNode

[LLVMdev] DSGraph::mergeInGraph usage?
...t Functions, but i'm
not going anywhere. For a Function F and DSGraph G, I tried this
(assumming no SCC in the callgraph):
vector<DSCallSite> CSV = G->getAuxFunctionCalls();
for (vector<DSCallSite>::iterator I = CSV.begin(), E = CSV.end();
I != E; I++) {
Value *V = I->getCallInst().getOperand(0);
Function &SF = cast<Function>(*V);
if (!SF.isExternal()) {
DSGraph *SFG = new DSGraph(SF, GG);
G->mergeInGraph(*I, *SFG, 0);
}
}
but the resulting graph has no new merged DSNodes, even though in my
test case there is a DSNode pointed by the CallInst in F...
