Dear Tianwei, You can use the -analyze option to the opt tool to tell the DSA passes to store their results in files. When you use the -analyze option, the DSA passes will create a separate file for each function (and possible one file to hold the globals graph). For this reason, I recommend running opt...

..."ds."); } .......... how these functions can be used in gdb? furthermore, are there any options which i can type in command line for DSA?, such as: opt -load=xxxxxx -print_the_local_analysis_result list.bc -o list-opt.bc also any suggestions for how to debug DSA efficiently?

..../configure make sudo make After that I run the program in the development guide. But it seems that the program is stuck in the function of virConnectOpenReadOnly. When I tried the command: virsh list --all, it is also stuck. So could anyone tell me what's wrong with this?

Hi, It would be nice if it were easier for relative novices to build whole-program bitcodes for large, complex applications with hairy build systems. Several readers of this list have been trying various approaches for a few months but as far as I know we haven't yet found a good general solution. Approaches that have been tried include 1) placing wrappers for the usual tools (gcc, ar, as,

...following instruction: %i = alloca i32, align 4 ; <i32*> [#uses=2] the following isa is true: isa<PointerType>(II->getType()) is that the type of a instruction is decided by the type of the result operand? and it has nothing to do with the opcode for a instruction? thanks. tianwei -------------- next part -------------- An HTML attachment was scrubbed...
