similar to: Building LLVM with VisualStudio 2017

At Arm we are not receiving any build bot mails from llvm.buildmaster at lab.llvm.org. Our IT is a bit in the dark what's going on here (they don't see anything in logs, no failures, no connections), their hunch is that is a "DNS (MX record) issue on llvm.org's end". I don't know who to contact or how to progress this. Anyone perhaps an idea? Cheers, Sjoerd.

the clang 3.5 loop optimizer seems to jump in unintentional for simple loops the very simple example ---- const int SIZE = 3; int the_func(int* p_array) { int dummy = 0; #if defined(ITER) for(int* p = &p_array[0]; p < &p_array[SIZE]; ++p) dummy += *p; #else for(int i = 0; i < SIZE; ++i) dummy += p_array[i]; #endif return dummy; } int main(int argc, char** argv) {

I’ve missed it. I did a quick search and the only thread I found is back from 2013. Could you please provide me with a link to the thread?

>The pdb reading code relies *very heavily* on Windows APIs can you make shure not to have any windows api stuff in the pdb-reader interface so its easy to - if someone wants to - implement an windows-api independent version (support reading under linux etc.) because the pdb format needs to be analysed anyway for writing pdb information on compile/link (in the future) Am 29.01.2015 um 19:20

Hello Lang, so you are part of the "Jitter-Team"? I'm really interested in this whole jitting-process. I wanted to know, is there a way to load other obj-files, than the one created with clang? Could I load - for example - a obj-File from VisualStudio? Or will the namemangeling fail? Kind regards Björn From: Lang Hames <lhames at gmail.com> To: bjoern.gaier at

Hi Lang, I'm using Windows. I was parsing an IR-File and added the Module to the ExectuionEngine. If I than searched for a function, I just got 0. But when the module had a main, I got an address. I solved the problem via a call to "generateCodeForModule". The JIT didn't even called my SymbolResolver in this special case. Could you please tell me, if there is a way to

All, Please help me defend Samba. We are having major performance problems when using VisualStudio to build projects. The source lives on the server, and the intermediate files are dumped locally to try to speed things up. One of the engineers downloaded a demo of NetManage/Chameleon NFS and it was significantly faster. Here are some numbers: samba-1.9.18p8 samba-1.9.18p8

>because with that generator the CMAKE_BUILD_TYPE variable is ignored >because it is a "multi-configuration target". thanks for the link, is that a bug in the CMake configuration (or better not getting any warning) or is there just documentation missing? so i can use --config Debug or --config Release and get the correct results - i hope that works the build takes hours

i want to integrate a C source JITer into my application but the resulting executables are too large is it possible to reduce the resulting libs/exe some way? current VS2017/svn build example: llvm-build\Release\bin\clang-interpreter.exe ~36MB for now (that can change later) - i want to jit simple c-code - no std library or something - x64 only - no deep/full architecture optimization needed -

Hi Bjoern, I’m a bit worried about taking symbols from modules, because some of the > symbols might change later when the code was compiled with the JIT Symbol names shouldn't change from the moment they're added to the JIT (i.e. after being fully mangled). Consistency of symbol names is a requirement for ORC to work. You could try hooking into the orc::Platform API for this:

Nice! Let me try to answer some questions, Before that I have to mention this is ORC version 2 APIs and this is where the project is moving forward. JITDylib is the symbol table, basically for a JIT Symbol it have an associated materializers, (you can think of it like an entity that generate the address for that symbol), Example: compiler are materializers. So to add symbols to your own JIT you

To whomever may be of help, I am a student in a graduate modeling class at the University of North Carolina at Wilmington. I am trying to get a STELLA model converted into R. I am in the process of trying to 're-write' the script into R, but I seem to be missing pieces (i.e. parm values) that are keeping me from being able to replicate this model into R. Does anyone have an idea of a

What does that mean for my code and the idea? I'm a really unexperienced LLVM user... -----Original Message----- From: Tim Northover <t.p.northover at gmail.com> Sent: Dienstag, 15.

Dear R experts, I would really appreciate if you had an idea on how to use more efficiently the aggregate method: More specifically, I would like to calculate the mean of certain values on a data frame,? grouped by various attributes, and then create a new column in the data frame that will have the corresponding mean for every row. I attach part of my code: matchMean <-

Hey Lang, That is really cool :D Is the creation of that table a Windows thingy or is this the way the LLVM handles it? Also… since it is COFF related – the never ending story of “finding my global constructors” first of all: Yes! I tried using the “initialize” function of LLVMJIT – however this only worked when I was loading a Module. When I added the object file (from the same source) the

Hello Alex, This is an interesting approach! Thank you for that! I understand the basic idea but sadly... My skills in handling the IR are not very high, so I can't imagine where and when to replace the calls to b() with the trampoline. The only thing I can handle would be creating that trampoline variable. Also will this approach be a problem for really time critical tasks? Since I replace

I could actually track down the cause of the problem: mainModue->getFunction("puts")->replaceAllUsesWith( llvm::ConstantExpr::getPointerCast( llvm::ConstantInt::get(llvm::IntegerType::get(context, 64), 0xF), mainModue->getFunction("puts")->getType() ) ); The problem is the line where I receive the type of the function "puts", it will crash the application

Hi Bjoern, For single object files you can override the needsToReserveAllocationSpace method that is inherited from llvm::RuntimeDyld::MemoryManager (make it return true) and then implement the reserveAllocationSpace method to allocate memory for all sections up front. There is no easy way to do this for multiple object files. I think you would have to mimic the memory size calculations
