...ld like to try implementing one myself. By debugger, I think it means something like gdb, where you can insert breakpoints, run code and observe layout of registers and memory at certain periods of time. If anyone has suggestions as to how this IR debugger should work please let me know. Thanks! Brenda -------------- next part -------------- An HTML attachment was scrubbed...

...e project, : http://blog.llvm.org/2010/04/intro-to-llvm-mc-project.html http://www.keystone-engine.org/ https://www.capstone-engine.org/ In fact, I'm also looking for something similar -- to be able to specify the machine instructions base solely on the IR.

...in it and pass it as an argument to the function that calculates an ordinal from it. I think that there must be some way to use the bitcode language to place byte values at a designated offset. Or use the command line to specify the section and offset for the data.

Thank you so much! What about discovering the instruction pointer value? Also, does anybody know how to embed an artifact as a resource in a binary? I'd like to have two text sections, and have one copied in from another binary.

...one can throw the executable into any debugger and get llvm level debugging. I've started a patch to revive this feature (DebugIR pass).

...r loop will have access to the following functions: http://llvm.org/doxygen/classllvm_1_1Instruction.html Alternatively, you can use the dump() operation to dump the instructions out. Unfortunately I don't know how to address your second question. That's stretching my knowledge in LLVM.

Is there a way to permit ssh sessions while denying sftp with openssh 3.8? In openssh 4.4+ this is possible using the Match directive with Force Command but I don't know how to configure this in older versions. Thanks in advance for any guidance. Brenda

...that one can only obtain the virtual memory address after linking the object files together. So how would the BlockAddress class help me when it's working on the IR level? If BlockAddress class is not the way to go, is there another api function that I can use to obtain the addresses? Thanks!

...he github version of LLVM, it seems like z3 is already incorporated: https://github.com/llvm-mirror/clang/blob/master/lib/StaticAnalyzer/Core/Z3ConstraintManager.cpp I guess my question is, what would the project contribute on top of the z3 manager that is currently implemented for LLVM?

...y easy with the linked guide. (instead of inheriting from Function Pass you can inherit frmo module pass) Afterwards, you can build your new pass against your LLVM source code and run it using the opt functionality.

...weeks it is. For weeks after 20, the value NA or 20, or even 20-30is fine. Thus for week 1: 0-2 week 2: 2-5 week 3: 2-5 week 4: 2-5 week 5: 5-12 ect.... It is not relevant if those intervals are captured in a matrix, in a vector or whatever. I hope that you can help me!

Hi Yuri, When you say code analysis, do you mean checking from source code itself, the intermediate representation, the assembly instructions or the binary?

The function that returns ENOMEM is actually copy_mm. It returns ENOMEM when dup_mm returns 0. copy_mm receives clone_flags and task_struct * tsk. I think tsk is pointing to the new task (the process being forked). copy_mm assigns some values into *tsk, then: tsk->mm = NULL; tsk->active_mm = NULL; then we check if current process has ->mm; if not, return 0 (effectively

Hello, I hope you are all doing well and thanks in advance. I need to program a transformation of a set of llvm bitcode to have some various techniques woven in. In particular, I need to resolve a given computed target address to one of several in the same way that the function of a dynamic library is resolved, but I need this resolution to happen in the binary target of my choice where I tell

There is llvmlite http://llvmlite.readthedocs.io/en/latest/ , but it doesn't seem to support reading individual instructions, based on these docs. I was thinking to make a simple code analysis tool to, for example, find all system calls that have unchecked return codes, but I can't find a binding for any scripting language. And I am averse to writing this in C++. Thanks, Yuri
