similar to: [GSoC 2018] Integrate with Z3 SMT solver to reduce false positives.

Hi all, Currently studying the impact of SMT solvers on Clang SA. Can anyone help in telling more about the SMT solvers use in clang SA ? ( Have already tested Z3 SMT solver implemented in GSoC 2018 , also looking for other SMT solvers if possible ) Thanks, Siddharth -------------- next part -------------- An HTML attachment was scrubbed...

We are currently implementing the backends for other solvers (you can follow the progress here: https://github.com/mikhailramalho/clang). So far we got Boolector, MathSAT and Yices ready. CVC4 should be done soon. When used to refute bugs, they all give roughly the same results: a ~5% speedup if there are refuted bugs or a ~5% slowdown if no bug is refuted. I've only tried to analyze one

Hi I am looking at open projects that LLVM want to implement and it seems to be a suggestion to write an LLVM IR level debugger. Is there any existing LLVM projects out there that already does such a thing? If not, I would 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

Program counter - EIP, RIP for x86/64. I need to obtain 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.

You are not

I created a loadable optimization following the tutorial at http://llvm.org/docs/WritingAnLLVMPass.html. I want to use the Z3 library, installed in my system, in my optimization. When I include z3++.h (the name of the library) in the code and use its classes, it compiles well, but when I try to run it it says: > opt: symbol lookup error: /home/giacomo/llvm/Debug+Asserts/lib/Acsl.so: >

The bitcode is only a representation of the IR, which is in SSA form. And SSA form assumes an infinite amount of registers, which is not offered by x86. When bitcode gets assembled/compiled to machine language, it breaks down the SSA form into non-SSA format. Personally I don't know how to use bitcode language to achieve what you want to do. The closest thing I can think of is the llvm-MC

I think I am in the first case, but I don't understand something, the -load option during which command? opt? and which file should I load? libz3.so?

I _think_ there is a problem with the license as well: Z3 is MIT, so clang would have to be released with Z3's license.

Anyone had any experience of using this phone with asterisk ? Trying to find out if I can provision it using tftp / http Thanks Julian -- Follow "Ode To Politics" by HB Tasker at http://twitter.com/HBTasker

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.

Hi All, About a month ago APC announced they were including MODBUS protocol support in their new APC UPSes. The technical note on this is here: http://www.apcmedia.com/salestools/MPAO-98KJ7F/MPAO-98KJ7F_R0_EN.pdf "Application Note #176 Modbus Implementation in APC Smart-UPS" The APC "announcement" appeared on their site in their user blogs by an APC employee, here:

If you can write what you want to output in C with asm statements, clang can show you what the IR should look like.

You can attach debug info to the Llvm module about LLVM IR, at which point one can throw the executable into any debugger and get llvm level debugging. I've started a patch to revive this feature (DebugIR pass). I've been sidetracked the past month, but I'll come back to it soon :) https://reviews.llvm.org/D40778 Cheers, Siddharth On Thu 4 Jan, 2018, 09:23 Brenda So via llvm-dev,

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

Hi all, I have a question concerning block address class in LLVM. I am currently working on a project where I need to obtain and manipulate basic block virtual addresses. I was searching the web and found the llvm::BlockAddress class (http://llvm.org/doxygen/classllvm_1_1BlockAddress.html). With this class I was able to obtain a printout like this: i8* blockaddress(@func_name, %bb_label) How do

Hi Kenneth, Can you elaborate what you mean by instruction pointer value? Like the actual instruction with opcode and operands? With the sample code that I showed you, the instrucrtion pointer in the innermost for 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.

Hi there.I''m Brenda from the Australia,I wanna work on a project relating to VOIP QoS.I wanna evaluate IP over ATM against IP over Ethernet on the following parameters relating to voice and video traffic; bandwidth consumption packet loss packet delay(latency) jitter traffic thoroughput Is this project feasible?Can I use NS to simulate the models?I hope you reply.Thanks.
