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.

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.

Hi, You can write it as if you are writing an optimization pass: http://llvm.org/docs/ProgrammersManual.html It sounds like your highest level is a module, hence you should write a module pass. There is example code on LLVM Programmer's Manual on how to do a function pass: Function* targetFunc = ...; class OurFunctionPass : public FunctionPass { public: OurFunctionPass():

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.

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

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

Hi, I have some basic questions. I'd appreciate if you can help me with them. 1. In the LLVM programmer manual, section "Finding call sites: a slightly more complex example", there is such piece of code: ------------------------------------------------- class OurFunctionPass : public FunctionPass { public: OurFunctionPass(): callCounter(0) { } virtual

Hi, I want to convert a function pointer call in the IR of MPlayer to a function call. For example, I have the following line: ... %10 = tail call i32 %7(%struct.demuxer* nonnull %0, i32 %1, i8* %2) #7, !dbg !863222 ... I want to set the target which is stored in %7 to a real function called "demux_lavf_control()" with the following definition: ... define internal i32

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

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 all, I am a fourth year EE bachelors student who is very interested in compilers. I have taken the only compilers course offered in my school and did an independent study with my CS professor. Although I'll begin to work in a couple of months, I definitely want to pursue my interest in compiler design and optimization as a PhD in the future. I am very interested in the z3 SMT solver

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. Best regards.

I am running asterisk 1.6.2.6 and have configured hints for our extensions and have a couple of Aastra 6755i test phones. The phones register fine but 'core show hints' shows the lines as idle even if they are in use. I read the wiki and see mention about needing to set call-limit in asterisk 1.4 but that has been depreciated in 1.6 so what is the way it should be done in 1.6?

interesting ... just curious, why did they delete "-debug-ir" to begin with ? Also, it's extremely interesting that gdb and lldb can be used to debug LLVM IR. How does your code work (on a high level)? A high level explanation will help me understand what you've done better. >From first glance, my idea is slight different because your code interfaces with gdb and lldb while
