Hi, I am newbie for LLVM. I need some help, I want to disassemble ARM binaries and perform some operation on LLVM IR and again back to generate ARM binary from modified ARM LLVM IR. How I can proceed for the same. Any tool or document will be highly appreciated. Thanks and Regards, Deep -------------- next part -------------- An HTML attachment was scrubbed... URL:

There's plenty of variations on the idea: Revgen/S2E, Fracture, Dagger (my own), libcpu, several closed-source ones used by pentest shops, some that use another representation before going to IR (say llvm-qemu), and probably others still I forgot about.

Hi, Is decompilation possible in general to the SSA form for binaries? I assume one has to make certain assumptions about code in general to get tools like these to work. For example if code like with dlsym or jit heap allocated functions can be incorporated at runtime it would seem that in general it is quite difficult to ascertain the boundaries of a basic block and insert the correct phi

> Here is my problem: > what does instrinsic / intrinsic function really means? You probably need to look at http://llvm.org/docs/ExtendingLLVM.html. Simply put, when you want to extend LLVM IR, say adding a new LLVM instruction, you have better try to add a intrinsic function [1] which has the same effect as the instruction you want to add. I don't think they are the same

Hi all, I have the file which is assemble, I want to convert it to IR. Are there some tools to do this in LLVM? Thanks, Yao -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.llvm.org/pipermail/llvm-dev/attachments/20130503/d7fd4741/attachment.html>

Does there exist a tool that could lift a binary (assembly for some supported target) to LLVM IR? If there isn't, does this seem like something that would be feasible? -------------- next part -------------- An HTML attachment was scrubbed...

Hello, I want to convert the following SAS code in S-plus script. I'm using S-Plus 2000 in Windows 95. PROC nlmixed data=dat cov df=39; PARMS A=-1.5 A1=0.5 B=1.1 C=.1 D=.7; IF SAMPLE="s" THEN I=0; ELSE I=1; Y=A+B*lconc + A1*I; F1=C+(D-C)/(1+EXP(-Y)); MODEL OD ~ normal(F1,s2e); Does anyone have any advice as to how to do this?

Hi,all. I've been reading the llvm source code for some days. Here is my problem: what does instrinsic / intrinsic function really means? Are these "the function belong to llvm and just belong to llvm"? Thanks. -------------- next part -------------- An HTML attachment was scrubbed... URL:

I want to transform elf binary to llvm IR, and do some instrumentation based on llvm. Is there any tool which can do the transformation?
