PV or HVM guest for OpenBuildServices Host (OpenSUSE based)
...nt. I thought about which guest type I should use. I am not that familiar with for example compiler optimization algorithms and so I asked my self the question would it be better to build up an PV or an HVM OpenSUSE DomU. What would be better? Does it matter if it is a PV or HVM guest for compiler optimazations and so on? Would be great when someone could give me an answer.

[LLVMdev] Pass Question
...into the LLVM optimizer so to insert functions for optimization before and after every function call.For example, I create a test file test.c. There is  a function f1() just printing out "Print f1", which is called in the main function. That's all the test.c do. Now I want to insert optimazation function opt_begin() before f1() and opt_end() after by adding the command line of my pass in the compilation option of llvm-gcc. Does anyone  have any idea about how to implement this? I would really appreciate if anyone can help me out, since I was stuck by this question for really  a long...

Otherwise you are going to have to send in your programs along with an explanation of how you compiled them exactly (exact sequence of commands) both for gcc and LLVM. Ciao, Duncan.
