Dear WizaRds, I am sorry to bother you with a newbie question, but although I tried to solve my problem using the various .pdf files (Introduction, help pages etc.), I have come to a complete stop. Please be so kind as to guide me a little bit along my way of exploring multivariate analysis in R. I want to test wether the means-vector mu1 of X, consisting of the means per column of that matrix

Hey all, I''m doing something of a node-node connection, and I want to eventually walk each node, pulling data from each node, and displaying the path. The DB table would just be columns of IDs that link to each other My catch is that these aren''t generic nodes, they are Models that could potentially connect to each other, and I don''t know how to

Dear list, I have developed a forward-time population genetics simulation environment simuPOP, which is a set of C++ (template) classes/functions wrapped by SWIG as Python libraries. R is used extensively as plotting and statistical analysis engine through RPy package. I use Python to wrap simuPOP since most the following can be easily done using SWIG or Python C API. However, since Python is

Dear list, I have to draw a simple plot. On y axe some numerical values that correspond to various categories on axe x. The table I am reading looks like: cat Obj1 Obj2 Obj3 max 23 27 34 ave 21 25 32 min 19 23 30 In order to avoid that the first column is reordered alphabetically I used: (found here http://tolstoy.newcastle.edu.au/R/help/06/09/33808.html) a <- as.character(table$cat)

​Hi all, I am using llvmlite for pyvex and I want the output of my code (which is written based on llvmlite) to be like pyvex. In pyvex, (https://github.com/angr/pyvex). Considering pyvex, I tried to implement the following statements in pyvex to llvmlite: for stmt in irsb.statements: if isinstance(stmt, pyvex.IRStmt.Store): print "ST%s(%s) = %s" % (self.endness[-2:].lower(),

Dear All, I came across an error message recently when constructing a reference class, an example is attached below, it looks like only if I call a specific method in advance, otherwise it cannot be found in defined method without using .self, this make it difficulty that sometimes in my initialize method, I need to call other method defined in the same reference class, the workaround for this is

Hello, I have a question concerning llvm-c. I have set up a function that needs to invoke an external method, in a other library. It has the following signature: void* NSFullUserName(void); The void* can be replaced with a i8*, that far I was able to get, but when my call is invoked, the engine gives me the following message: LLVM ERROR: Tried to execute an unknown external function: i8* ()*

Hi All I am a novice LLVM user trying to use LLVMConstIntOfString using the c api to get a integer of arbitrary size from a hexadecimal string. Example code follows: LLVMContextRef context = LLVMContextCreate(); LLVMValueRef value = LLVMConstIntOfString(LLVMInt64TypeInContext(context), "0x0000000f0000ffff", 16); This is working properly as expected. However I have noticed that

Dear folks, I?m trying to build a function to create and make available some variables I frequently use for testing purposes. Suppose I have a function that takes some inputs and creates (internally) several named objects. Say, fun1 <- function(x, y, z) {obj1 <- x; obj2 <- y; obj3 <- z <missing stuff> } Here is the challenge: After I run it, I want the objects to be

Have I correctly inferred below, how I build IR and debug info for a function type and a function (value), in particular, how to supply the names of the formal parameters? To create a function in llvm IR and give names to its formal parameters, I must: 1. Build a LLVMTypeRef for the type of each formal and the function result. 2. Build a function type using LLVMFunctionType, from the results of

mingw, llvm 2.6 (buid with llvm-gcc) Example source code: http://npcontemplation.blogspot.com/2008/06/secret-of-llvm-c-bindings.html I change LLVMCreateJITCompiler(&engine, provider, &error); to LLVMCreateJITCompiler(&engine, provider, 3, &error); $ llvm-gcc `llvm-config --cflags` -c fac.c $ g++ `llvm-config --libs --cflags --ldflags core analysis executionengine jit

I need to set the 'next' attribute on a parameter. If the function is to be directly called, i.e., a function constant, I am getting what I want as follows (using the C 'Core.h' binding) 1) Build a function type, using LLVMFunctionType. 2) Build a function value, passing the result of 1) to LLVMAddFunction 3) Go through the formal parameters of 2), using LLVMGet[First|Next]Param,

Hello, I've spent some time with the LLVM documentation and am beginning to grasp a few things, but I sometimes need very literal statements to actually understand things. My first question is about StackMaps: Is it true that llvm_gc_root_chain is an API? I've been trying to understand how exactly one accesses this structure and no where in the documentation does it mention this is a

I have created the function prototype with the following code: const uintmax_t methodNameSize = 1024; const char methodNameTemplate[] = "llvm.memcpy.p0i%llu.p0i%llu.i%llu"; char methodName[methodNameSize]; // Create the methodName. memset(methodName, 0, methodNameSize); sprintf(methodName, methodNameTemplate, dstSize, srcSize, lengthSize); // Search for the

Hi, I'm attempting to use MCJIT with the C interface with llvm-3.9.0, and it doesn't seem to work. This code is derived from Paul Smith's example code: int main(int argc, char const* argv[]) { LLVMModuleRef mod = LLVMModuleCreateWithName("my_module"); LLVMTypeRef param_types[] = {LLVMInt32Type(), LLVMInt32Type()}; LLVMTypeRef ret_type =

Hello, I'm trying to get to grips with the c interface of llvm intending to eventually develop a front end for Purebasic Though I've hit the wall already writing an iterative Fibonacci function. While I think the module dump looks ok it doesn't work for any input > 2 the function returns 2, the loop only executes once Hopefully someone can see what the problem is from the

A nice side effect is that everything is added to the interface. So it is easy to add a small proxy over the lib that shows which parts of the llvm-c API that is exercised by the tests. (have that in my bindings)

Hi David, I'm not certain, but to me the "LLVMSetTarget(module, "i686-apple-darwin11");" line looks suspicious. I'm not familiar with all the ins and outs of how target triples get handled, but it looks to me like that's requesting 32-bit code. I think that if you omit that line completely then the target will be inferred from the execution environment. My best

Hello, [Using LLVM r155315, according to `svn log | head`] I am experimenting with programatically building and jitting functions in a module, and I seem to be coming across a crash in some generated code. Using the llvm-c interface I build up the module which dumps like this: ; ModuleID = 'MyModule' target datalayout = "i686-apple-darwin11" target triple =

Hm. I may misunderstand, but I'm not sure that's an improvement over the problem you're trying to solve. How about something like this? (Please forgive any accent; I don't speak snake fluently.) class Pet(object): @staticmethod def new(): # Create a 'free' pet. It can later become owned, but not to more than one owner. return
