similar to: [LLVMdev] how to invoke C functions in llvm IR ?

If I have an operand as a Value from an instruction like: Value* V = opnd->get(); and I am sure this is a variable, I want to know the variable name (in source code) for this Value object. I am doing it like this: const Function* Func; if (const Argument* Arg = dyn_cast<Argument>(V)) { Func =

Outliner does not expose any of that. I have not made a lot of effort to understand the full discussion here (so what I say below may be off-base), but I think there are some cases where

Hi, I did "dtrace -l" on libc.so.1 with "_c??????" matching pattern and yield only two probes but there are 6 of them matches that pattern when invoke "nm" on libc. Why? See below for details: %dtrace -w -qn ''BEGIN {system("dtrace -l -mlibc.so.1 > libc_dtrace");} pid$target:libc:_c??????:entry{}'' -c ''sleep 1'' %

Thanks for the tip - getting closer: $ ./capi_test 5 6 args[0]: 5 args[1]: 6 result: 4294959200 Here's the code I changed: printf("args[0]: %d\n", (int)LLVMGenericValueToInt(args[0], 0)); printf("args[1]: %d\n", (int)LLVMGenericValueToInt(args[1], 0)); uint64_t (*func)(); func = (uint64_t (*)())LLVMGetFunctionAddress(engine, "sum");

To create a stack based (local) 64 bit integer in LLVM IR, I used: Value *var = builder.CreateAlloca(Type::getInt64Ty(Ctx)); I wish to pass this variable to a function "void foo(unsigned long)". I created the signature of function foo() as follows: Constant *func = M->getOrInsertFunction("foo", Type::getVoidTy(Ctx),Type::getInt64Ty(Ctx), NULL); To pass the newly created

Hi, I have a simple swift code from which I generate IR code with ‘swiftc test.swift -emit-ir -o test.ll' When I try to run the .ll file or apply optimization with opt, I get errors like this one: lli: test.ll:548:110: error: expected instruction opcode %9 = cmpxchg i64* bitcast (%swift.type*** @field_type_vector_TipCalculator to i64*), i64 0, i64 %8 seq_cst seq_cst

Hello everyone, I wanted to copy a function from one file to another. The file that I wanted to copy the function into contains a function with the same name and same number of instructions. I decided to just replace the instructions with those of the other function. I am doing all of this from within a function pass. *1.* I created a function pass in which I extract a function using

Dear R users, We have some programs for the specific task in our research, but they were very commonly used. We want to make some functions for them, anybody can recommend any good tools to facilitate us to create R functions even without going deep into the theories of R functions ? Any suggestions or help are greatly appreciated. -- With Kind Regards, oooO::::::::: (..):::::::::

Hi, I'm writing a C function that has to call a R function with multiple arguments. I've read the relevant section in Writing R Extensions, and searched the R site, mailing lists as well as rseek. I managed to call the function, but I'm now having trouble creating the argument list. I tried to create a pairlist of the arguments and send it to the R function. The R function however

Hi, I've written some helper functions which are used by another function (called func()). When func() is sourced I dont want the helper function to be seen in the global namespace (as shown by ls()). Currently what I have done is: func <- function() { helper1 <- function() { ... } helper2 <- function() { ... } # some code } Is there anyway to take the functions

I want to add command line (shell) like statement to C is it possible to implement this syntax by clang and llvm? The syntax is like func arg1 arg2 ... argn; and define func like void func( int arg1, int arg2, ..., int argn) { ...} Charlie -------------- next part -------------- An HTML attachment was scrubbed...

Hi R Users, Thanks in advance. I am using R-2.5.1 on Windows XP. I am trying to call C code (testCX1.C) from R. testCX1.c calls another C code (funcC1.c) and returning a value to testCX1.c. I like to have this value in R. My steps are below: 1. R CMD SHLIB testCX1.c funcC1.c (at command propmt) 2. It creates testCX1.dll with warning (but testCX1.dll works):

Hi all, Recently I have implemented a transformation pass based on LLVM3.5 and its function is to duplicate the function's argument list in a bytecode file and replace all use of original function with modified function. In LLVM3.5, the pass can work properly. However, when I tried to transplant the pass to LLVM3.9, the error "Argument value does not match function argument type!"

I've developed a dll (win32) of a bunch of functions prototypes as: /* for building on *nix */ #ifndef WIN32 #define __stdcall /*nothing*/ #endif void __stdcall dbh_2_height( const unsigned long *func_idx, const unsigned long *metric, const unsigned long *species, const double *dbh, double *pred_height ); and have created a R interface

Hi, I've been using the package "graph" in the BioConductor assortment and writing some functions based on its classes. My question is not specific to this package or BioConductor (I think), but it serves as a useful example. I recently wanted to look at the code for the function "edgeMatrix" for the class "graphNEL". Usually I would type > func.foo and

Hi, Is there another way to pass arguments via a vector to arbitrary functions as in the following code example without using a series of if else statements? f <- test(func, x, parms, fargs1, fargs2, ...) { # parms is a vector of parameters to func. # ... is for use by f, not by func. n <- length(parms) if (n == 0) y <- func(x) else if (n == 1) y <- func(x,

Maybe I explained badly... Imagine this: -- a.ll -- %struct.x = type { i32, i32 } %a = call void @func (%struct.x %b) -- b.ll -- %struct.y = type { i32, i32 } declare i32 @func (%struct.y)

What I want to do is put the arguments I supply to a function into the title of a plot Say I'm calling func.1 func.1(a=4,b=4) plot(....,..., title("a=4, b=4")) If I'm calling func.1 with different arguments, I want the plot title to reflect that. A small detail is that func.1 might have an argument with a default like c=a+b. I tried using expression but couldn't get it to
