Dear Prof. Adve, Now I can use llvmgcc to compile a .c file into .bc file. But I still have trouble simply run the .bc code. Below is the sequence I got when I tried. I really don't know what's going on here. Please let me know how can I fix it.

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

Dear LLVM: I wrote a small testcase and I can compiler and run it with gcc, But with llvm, I got weird error like the following. I really don't know what's going on. Could you explain?

Sorry I got really overwhelmed by so many classes and member functions in LLVM. So would you please clarify some problems I have? 1. If I see this instruction in the function. %S.i = alloca %struct.SimpleStruct Suppose SimpleStruct is as following: struct.SimpleStruct = type { int, double } When I read the instruction, how can I know the type of simplstruct, should I use 'getType'

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!

1. What is the difference between DSNodeHandle and DSNode? What do the functions getLink() and getSize() do? 2. In the previous email, you mentioned that we can use DSNode::getPointerSize() to get the number of links, But I checked the doxygen documentation, there is no such member for DSNode. 3. Previously I use the following code: for( df_iterator<DSNode*> I = df_begin(pnode),

Hi, I have some basic questions. I'd appreciate if you can help me with them. 1.

Finally lli and llvmgcc can work under my directory. I wrote the following simple program and compiled it using gcc and then run it without any problem. But when I tried to compile it using llvmgcc and lli, llvmgcc gave me the following error message which I cannot understand: xli3|csil-suna37|~/cs426|[181]% llvmgcc test.c -o test test.c: In function `init': test.c:10: warning: cast to pointer from integer of different size When I run it using lli, it even gave me the following segmentation fault: EXCEPTION OCCURRED [Segmentation Fault]: >#0. int "main"()...

Hi, I have a question about the modify of instruction: Say I want to modify %a = getelementptr %struct %S, long 0, ubyte 1 into %a.f0 = getelementptr int* %S.f0, long 0 There are 3 ways I can think of to implement, but I'm not sure what should I do. 1. I can use new GetElementPtr to create a new instruction and use ReplaceInstWithInst() function to replace the old one. 2. I can use new

In the section expaining "dyn_cast" There are following lines of code: if (AllocationInst *AI = dyn_cast<AllocationInst>(Val)) { ... } I cannot understand how you take a operand, a value, and cast it into a Instruction. Can you explain it for me? Another common example is: // Loop over all of the phi nodes in a basic block BasicBlock::iterator BBI =
