Hi, I'm following the Kaleidoscope tutorial (which is very good btw) and am having difficulties having function calls for functions that haven't been defined getting resolved to plain C++ functions. In the tutorial (end of chapter 4), executing "extern putchard(x); putchard(120);" should execute the corresponding C++ function defined in the same file. Unfortunately in my case it

Hi I hope this is a proper place to put my question. I've compiled Kaleidoscope from "Adding JIT and Optimizer Support" tutorial. Basically it works just fine but when I try to run extern'ed putchard function it aborts. Please, tell me what am I doing wrong? Here is more information: My PC runs FreeBSD. I've copied the toy source code exactly and didn't change it.

Hi all, I am new to LLVM and have been working through the Kaleidoscope tutorial. Everything is working fine so far except for local externs (as opposed to things like the math functions, which are working). Note that I have seen this bug with the reference code listing, as well as my own code. link to code: https://llvm.org/docs/tutorial/LangImpl05.html#full-code-listing [c34n10 kaleidoscope]

I am new to llvm so I might be missing a critical step. My system is Fedora 12 but this also happens in Mac OS X 10.6.2. Here are the steps I used to compile llvm: export TARGETS=x86,x86_64,cpp export INSTALLDIR=/home/rovitotv/llvm ../llvm-2.6/configure --prefix=$INSTALLDIR --enable-bindings=none --enable-targets=$TARGETS --enable-optimized --with-llvmgccdir=$INSTALLDIR

Hi all, My example compiler is working fine on Linux, including the extern'd functions (via -rdynamic flag on linker), but a friend on a MacOS (Darwin) cannot find the extern'd function. LLVM ERROR: Program used external function 'printVar' which could not be resolved! I've read some posts on the web indicating problems with the -rdynamic option on Mac's GCC, but I'm

First, you have to call llvm-g++ to use the llvm-gcc front end, but it doesn't matter here. I'd like to suggest that you use pastebin to put your code and the send us the link, so that we can download it. The problem is that TheExecutionEngine is set to NULL (maybe because of a previous error), but it will be really better if you use pastebin. On Wed, Feb 17, 2010 at 6:01 AM, Todd Rovito

To try to find out why it was crashing, I followed the trail of function calls: C:\llvm\examples\Kaleidoscope\Orc\initial\toy.cpp auto ExprSymbol = J.findUnmangledSymbol("__anon_expr"); JITSymbol findUnmangledSymbol(const std::string Name) { return findSymbol(mangle(Name)); } JITSymbol findSymbol(const std::string &Name) { return CompileLayer.findSymbol(Name,

Hi, I'm currently working my way through the tutorial with LLVM 3.9.1 on Windows (finished chapter 4) and stumbled over a few things which could be improved: - "LLVMContext" does not exist as a variable -> "TheContext" - Chapter 3: 5 times - Chapter 4: 1 time - Chapter 5: 4 times - Chapter 6: 2 times - Chapter 7: 2 times 3.4. Function Code

Addendum: this still fails: auto ExprSymbol = J.findSymbol("putchard"); As yet, I have no idea why - that symbol even seemed to be exported: extern "C" double putchard(double X) { putchar((char)X); return 0; } On Fri, Apr 1, 2016 at 2:42 AM, Russell Wallace <russell.wallace at gmail.com> wrote: > To try to find out why it was crashing, I followed the

I found these lines in the BrainF example: //declare i32 @getchar() getchar_func = cast<Function>(module-> getOrInsertFunction("getchar", IntegerType::getInt32Ty(C), NULL)); //declare i32 @putchar(i32) putchar_func = cast<Function>(module-> getOrInsertFunction("putchar", IntegerType::getInt32Ty(C),

It seems checkpatch errors krept in, this is a first go. Next run will go into usr/kinit directory. No code changes, just codingstyle fixes (verified with size(3)). maximilian attems (5): [klibc] sleep: have argument on next line [klibc] readklink: remove unneeded braces [klibc] mount: whitespace policy [klibc] ls: fix various checkpatch complaints [klibc] tests: checkpatch fixlets

Hello, in order to get ready for the upcoming LLVM 3.1 release, I checked out the 3.1 Release branch. However, unlike with LLVM 3.0, `llvm-config --libfiles` now also reports files that belong to targets that I did not build (and that are thus not available). Is this expected?

Hello, I have a simple question. How to create "dummy" function which will have no functionality behind (return nothing and do nothing)? Currently I'm trying to do this: llvm::Constant* c = Module.getOrInsertFunction("dummy", FunctionThatNeedsToBeReplaced.getFunctionType()); llvm::Function* dummy = llvm::cast<llvm::Function>(c); This way I create new function that
