Dear llvm, I just tried to compile a simple file hello.c. But each time I used llvmgcc hello.c, it gave me the following error: xli3|csil-suna33|~/cs426|[13]% llvmgcc hello.c as: error opening '/var/tmp//ccapglpE.o': file exists! Use -f command line argument to force output I really got confused. Could you please let me know what's wrong? thanks, Jerry

When I tried to run the previous .bc code with lli, I got the following errors: xli3|csil-suna33|~/cs426|[48]% lli he2.bc Unresolvable reference found: <long>:1! Unresolvable reference found: <long>:1! Unresolvable reference found: <long>:2! Error parsing 'he2.bc': No module loaded: Error resolving method values! So right now, I cannot do anything. Could you please l...

When I check out llvm this morning. I got this error, so I couldn't check out. Looks like the disk is full.. Please let me know how to fix this problem.

Dear LLVM, I was wondering what's the difference between BasicBlock and MachineBasicBlock in LLVM. If I want to solve a data flow equation problem, which one should I use? Thanks, Jerry

Dear LLVM, Is there any simple way to decide whether there is a control path from one Basic Block to another Basic Block? thanks, Jerry

Acutally I mean whether we can start from a node in the graph and follow a path which might be very long, to reach another node. Is there a quick way to do that? thanks, xiaodong On Mon, 11 Nov 2002, Chris Lattner wrote: > > > Is there any simple way to decide whether there is a control path from one > > Basic Block to another Basic Block? > > No efficient way, but you

Dear LLVM, If I have a DSGraph dsg, I want to duplicate a DSgraph which is exactly the same with dsg. How should I do that? Should I use DSGraph dsg2 = dsg; or use some other methods? Thanks, xiaodong

Dear LLVM, I need to do interprocedural analysis for my project. I was wondering if you can tell me how to create Bottom Up DSGraph and Call Graph in the program. I know DSGraph *dsg = new DSGraph( F ) can create a DSGraph, but looks like that's only local DSGraph. I also need to know how to create the call graph for the whole module in the program. Thanks, xiaodong

When I tried to compile the program, I got this error: ../../../include/llvm/Analysis/DSGraph.h: In member function `virtual bool <unnamed>::GlobalMemLeakage::run(Module&)': ../../../include/llvm/Analysis/DSGraph.h:38: `void DSGraph::operator=(const DSGraph&)' is private MemLeakage.cpp:87: within this context gmake: *** [Debug/MemLeakage.o] Error 1 I don't
