[LLVMdev] Automake and llvm-config
Hello,
I'm using autotools to build my little lang.
So I want to have something like this in my Makefile.am:
mylang_SOURCES = mylang.cpp
mylang_LDADD = mylib.a `llvm-config --cppflags --ldflags --libs core
jit native ipo`
But automake complains:
tools/Makefile.am:8: linker flags such as `--cppflags' belong in `mylang_LDFLAGS
I tried different workarounds but nothing helps :(

[LLVMdev] Equivalent types
Hi!
I have this error while building my code:
Assertion failed: ((i >= FTy->getNumParams() || FTy->getParamType(i)
== Params[i]->getType()) && "Calling a function with a bad
signature!")
Actually I'm trying to load functions from .bc file and use them in
the code that I'm building with IRBuilder.
I found that function parameter type is %struct.reValue* and

[LLVMdev] Kaleidoscope doesn't work properly
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.

[LLVMdev] Question on JIT optimizations
Hi,
If hope this is the right list to post a question like this. If not,
my apologies -- please redirect me.
Following the Kaledoscope example I am trying to write a simple JIT and
compile my own small language using LLVM. Compilation happens using the
C++ api by constructing a VM and emitting code using the api (just as the
Kaledoscope example).
The code in this setup will be optimized

code quality will be dreadful if you don't promote memory accesses to registers
right at the start, using eg mem2reg or scalarrepl.

[LLVMdev] ARM opcode format
Hello,
So the current JIT will be superseded by the MCJIT completely and no
further development should be expected for the current JIT? In any case, I
am definitely interested in submitting a patch if you could help me by
sending me in the right direction, since I really want this working.
I managed to reproduce this behavior in LLVM 3.0 by modifying llc to read
my .bc file and try to JIT the

[LLVMdev] Optimization of calls to functions without side effects (from Kaleidoscope example)
I'm using the gvn pass, not sure about basic-aa.
I've copied the code as-is from http://llvm.org/docs/tutorial/LangImpl4.html#code and added "F->addFnAttr( Attribute::ReadOnly )" after "Function *F = Function::Create(FT, Function::ExternalLinkage, Name, TheModule)".

[LLVMdev] LLVM and C++
Hi
I want to use LLVM to generate a code working with C++ objects.
I've got basics of LLVM IR generation from Kaleidoscope and other tutorials.
Then I tried to llvm-dis'assemble llvm-gcc'ompiled C++ program and I see
how to generate all this strangely named functions and how to run
constructors and destructors. So I can imagine how to generate C++
compatible code with LLVM. But it

Thanks, -rdynamic helps! It's a pity that it's not written in the tutorial.
Also I'm interested how can I provide a mapping?

[LLVMdev] How can I create CallInst with a pointer to function
Hi
I mean when I have in my program pointer to a function how should I
build IR to call the function by the pointer?
Or how can I create llvm::Function with a pointer to a function?
I want to have something like this:
int factorial (int n) { return n==0 ? 1 : n*factorial(n-1); }
typedef int (*intFunc) (int);
intFunc fptr = factorial;
Value * N = ConstantInt::get(Type::Int32Ty,10);

[LLVMdev] Kaleidoscope toy4 failure seg fault on llvm::ExecutionEngine::getTargetData (this=0x0)
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

[LLVMdev] Kaleidoscope toy4 failure seg fault on llvm::ExecutionEngine::getTargetData (this=0x0)
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.

[LLVMdev] make SHARED_LIBRARY=1 broken?
Hi,
Until recently I've been building LLVM with SHARED_LIBRARY=1. However, sith
current svn, build now fails with unresolved symbols building opt. I've done
a clean checkout, configure and make so it's not down to any local changes
I've made.
I'm building with:

[LLVMdev] Kaleidoscope tutorial failed at Chapter 4...
Hi everyone. I am using LLVM 2.4 release to practise the tutorial at
Kaleidoscope Chapter 4.
I built the LLVM library, and created my own project, and then paste the
code from the tutorial into my own project. Then after compiled and built
it, I passed the built stage. (I am using visual studio 2005 )
However, when I tried to input some code in the command line window, the
sample program crashed.

ARM JIT is broken in many ways. So, what you're seeing is

[LLVMdev] make SHARED_LIBRARY=1 broken?
I suspect my change adding --enable-shared broke you, since that
configure option didn't exist before last week (r97119).
SHARED_LIBRARY is not one of the variables you're supposed to be able
to set on make's command line
(http://llvm.org/docs/MakefileGuide.html#variables). What are you
using it for? What happens if you remove it?

Rob,
I can reproduce the behaviour you observe using llvm top-of-tree.
I will try to look into it.
