similar to: Parsing llvm IR

Hello All, I would like your help to learn how to traverse an LLVM DAG and perform some analysis. I know that llc can be used to view a DAG, but I would like to manipulate them. In particular I'm interested in the instruction selection and the scheduling DAGs. I have read the documentation about writing an analysis pass and I know how to traverse a basic block on a LLVM IR assembly file, but

Hi All, Is this possible to generate LLVM IR from any static/dynamic link library? I have some static and dynamic link library and I want to generate LLVM IR as I want to obfuscate these libraries. Is there any way to do the same. Please give me some pointers on this. Thanks, Deep -------------- next part -------------- An HTML attachment was scrubbed... URL:

Dear Raul, Instruction selection and instruction scheduling is, to the best of my knowledge, done at the MachineInstr (MI) IR level. The documentation you've read is on the target independent LLVM IR. You will probably need to read the documentation on LLVM's code generator. The documents on Writing an LLVM Backend, the LLVM Target Independent Code Generator, and Machine IR Format

Hi, I am a graduate student in computer science.I have taken a programming languages course this semester and I am having great fun building interpreters.I am planning to build toy compilers in the winter.I would love to participate in GSOC 2016 contributing to LLVM.Could anyone let me know desirable skills should be developed to contribute to LLVM ? Also I would like to know the open projects

​Hi. I want to change order of code basic blocks in memory. I visited " http://llvm.org/docs/ExtendingLLVM.html" page and it advised me to ask it before any effort. What parts of LLVM help me and how? I am a newbie on LLVM. Thanks. -------------- next part -------------- An HTML attachment was scrubbed... URL:

I am trying to compile llvm-tv as per the instructions from the link - http://llvm.org/svn/llvm-project/television/trunk/README.txt The poolalloc doesn't seem to be in synch with the llvm svn version mentioned (78786). It is giving lot of errors during compilation. I fixed a few of them by bringing in functions/header files etc. wherever required from the mainline llvm. But this exercise

Thanks John. I verified that and poolalloc builds with LLVM 3.0. I used clang for compiling wxWidgets, LLVM 3.0 and poolalloc. But llvm-tv build still gives build error. I take it that llvm-tv is still incompatible with these versions of poolalloc and LLVM 3.0. I think the code is manageable - couple of files in lib,include and some 30 odd small files in tools directory. I'll have a look at

Hi, Diego, Thanks for your quick reply. Inserting a copy instruction may not work here because I have a limitation of virtual register number. I need to assign registers with ssa form to registers without ssa form. I will look the source code you point out.

Thank you very much John. With an environment variable I need to take some special care, but it looks like the only way to go.

I believe the file you want to modify

I fixed all the other build errors. This is the only one pending.

Thanks John. Does this solve the problem of analysis availability though? If I still have to run the function analyses manually, I might as well keep rolling with the CallGraphSCCPass. (I probably should have mentioned that this is what I’m using right now.) Félix > Le 2015-05-19 à 10:12:32, John Criswell <jtcriswel at gmail.com> a écrit : > > On 5/18/15 10:45 PM, Félix Cloutier

John, Yes, I'm taking care about application as usual.

Sir, I am interested in adding a new analysis or optimization pass and building the getting started guide as a project for gsoc.

John, thanks for your helpful advice. My ultimate goal is to construct a full instruction-level program dependence graph for a given IR file. The hard point is how to establish the correct data dependence edges when some function arguments are multi-level pointers. To solve this problem I hope to check the point-to level for each pointer variable. I think the data dependence through pointers can

Sir, I am interested in add a new pass. I have read about analysis, transformation passes. Can you help me with some example ideas?

Hi, I am wondering if anyone could run ArrayBoundChecks located in SafeCode-llvm37 (https://github.com/jtcriswell/safecode-llvm37) on llvm-3.8? Thanks. Syed -- Rafi

Thanks John. I guess I will use a ModulePass, so when I am implementing the “runOnModule” function, do I have to loop through all the functions, for each functions all the BasicBlocks and for each BasicBlock all the instructions or given the Module I have to call the CallGraph directly? Is there an example out there? I can’t find anything. Thanks. Simone > On Feb 24, 2015, at 13:29, John
