similar to: Crashes when adding VisualStduio generated object files to the JIT process

Hello, I append another clue I found out: The problem is definitely not caused by "__ImageBase" the problem comes with the "OFFSET". I generated another object file which crashed. The commonality: mov edx, DWORD PTR ?normalPlanschbecken@@3HA ; normalPlanschbecken lea rcx, OFFSET FLAT :??_C at _0CC@LCMJAIPO at Reading?5?$CCnormalPlanschbecken?$CC?5?$CFi@

I wouldn't be surprised if JITing COFF files on Windows doesn't work so well, since the object file format assumes most symbols are dllimport or within the local 2GB module address range. I'm not familiar with the current JIT state of the art, though. On Thu, Mar 22, 2018 at 1:45 AM via llvm-dev <llvm-dev at lists.llvm.org> wrote: > Hello, > > I append another clue I

Hey Lang and Stefan, Using dllimport on my “planschiValue” actually worked! But I have no idea why, because the relocation is still a REL32 if I use dumpbin… So how is it possible for that to work? However… when I load an COFF object file, am I able to change the relocations to dllimport somehow? I honestly can’t imagine how this would work since the machine code is probably already adjusted to

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

Hi Björn I made a workaround for this specific issue a long time ago for the Projucer C++ JIT Engine. It basically forwards the call to another stub that provides enough space to encode a full 64-bit address. The patch is based on LLVM 3.9, so I guess it won't work out-of-the-box on a recent release, but it may give you enough hints to figure it out on your own:

Hi Folks! Just started using the gamlss package and I tried a simple code example (see below). Why the negative sigma?

Hi Nico, Reid, and Anton, I missed the discussion when I implemented dllexport/dllimport for our local tree. I essentially implemented your approach#1. I was trying to avoid the various external_linkage + some_attribute approaches because it seems that external_linkage would imply the external linkage without the dllimport/dllexport semantics, and there may be existing compiler codes that rely on

Hello, while improving and extending support for dllexport/import I have noticed that the current way these are implemented is problematic and I would like some input on how to proceed. Currently dllexport/dllimport is treated as linkage type. This conflicts with inlined functions because there is no linkage for the combination of both. On first though, combining both doesn't make sense, but

Hello all, Is there a way to export C++ "unsigned" integer to R? (I am trying to parse files in "BPMAP" format, and some variables are of type unsigned int (first declared in C++) ). I know that to export signed integer to R, I can do the following in C++: int Some_INTEGER = 5; int *p_myInt; SEXP myInt; PROTECT(myInt=NEW_INTEGER(1)); myInt[0] = Some_INTEGER;

Hello LLVM-Mailing-List, I discovered a strange behavior when dealing with object files generated by the compiler of Visual Studio 2015. When jitting bc files I also add object files to look up functions. These object files are coming from visual studio. When using a switch case instruction that compiler often generates code based of __ImageBase. I show you a short snippet of the assembly

Dear ALL-R helpers, I want to let R get vector from c ,for example :numeric array ,vector .I saw some exmple like this : /* useCall3.c */ /* Getting an integer vector from C using .Call */ #include <R.h> #include <Rdefines.h> SEXP setInt() { SEXP myint; int *p_myint; int len = 5; PROTECT(myint = NEW_INTEGER(len)); // Allocating

Hi My code is as follows :- example.h #include"iostream.h" using namespace std; typedef int MYINT; void sum(MYINT a, MYINT b); example.cpp #include"example.h" void sum(MYINT a, MYINT b) { MYINT c; c=a +b; cout<<c; } example.i %module example %{ #include"example.h" extern void sum(MYINT a, MYINT b); %} #include "example.h"

Hi all, myint=function(mu,sigma){ integrate(function(x) dnorm(x,mu,sigma)/(1+exp(-x)),-Inf,Inf)$value } mymu=seq(-3,3,length(1000)) mysigma=seq(0,1,length(500))[-1] k=1 v=c() for (j in 1:length(mymu)) { for (i in 1:length(mysigma)) { v[k]=myint(mymu[j],mysigma[i]) k=k+1 } } Basically, I want to investigate for what values of mu and sigma, the integral is divergent. Is there another way

The following patch changes export.h so that the dllimport/dllexport attributes work with mingw/mingw-w64 and others: - changes _declspec keyword to __declspec: the former may not be defined by some toolchains. - changes the _MSC_VER condition to universally _WIN32: MSVC, as well as GCC supports this. Attached patch: declspec.diff Regards. -- O.S. -------------- next part --------------

After a long processing, I was able to create a version of a small C# class that was able to emulate the rproxy by P/Invoke. This is mostly to find a workaround a performance problem of the StatConnector. It's almost work but ... I have strange memory exception when I call the print function. The variable seems to not survive from one call to the other. As there is no debug symbol for

Hey everyone, is there a way to get the name of all symbols that are stored ("stored" is not the right term - is it?) in my current ExecutionSession? I know by now that you can use "lookup" to get symbols, but this requires knowing those names. Mhh... I guess that is my shortest so far question xD Thank you in advance for any help!

Hello, I am just a beginner of R 1.9.0. I try to construct a predictive score for the development of liver cancer in cirrhotic patients. So dependant variable is binanry (cancer yes or no). Independant variables are biological data. The aim is to find out a cut-off value which differentiate (theoratically) from normal to pathological state for each biological data. How can I step in procedue to
