Hi, I'm having problems while using a custom pass with opt. The pass compiles and links just fine but, when I try to use it with opt: opt -load LLVMmyPass.so -my-flag -f aes.bc -o aes_bb.bc opt refuses to load it with the following error: Error opening 'LLVMmyPass.so': LLVMmyPass.so: undefined symbol: _ZN4llvm9DebugFlagE -load request ignored. and then complains that the flag

Hi all, I'm having trouble when trying to reuse some functions that use Boost::Exception into my LLVM-based application. As far as I know, LLVM turns off Exception handling (apparently for performance reasons), so I get the following link-time error in a few places: "undefined reference to `boost::throw_exception(std::exception const&)" When I compile the external code from

Hi all, I came across something that seems to be a bug in the dragonegg option that emits LLVM IR. ¿Can anybody reproduce the error, or see what's wrong? ¿Should I post it somewhere else in case it's really a bug? Thanks ahead! With this simple program: * #include <stdio.h> #include <string.h> int main(int argc, char** argv){ char a[8] = "aaaaaaa";

Dear everyone, I want to traverse call graph, but I have some trouble . In my pass MyPass which need to traverse call graph, I firstly added the CallGraph analysis to the pass requirements by *AU.addRequired<CallGraph>();* My pass MyPass then will be added to a pass manager by *manager.add(new MyPass());* and then I want to traverse the call graph such as: CallGraph CG =

I recall having a similar problem while coding my own special-purpose "opt". My guess: try adding the following lines before your pass is inserted into the PassManager: PassRegistry &Registry = *PassRegistry::getPassRegistry(); initializeIPA(Registry); You might require other library initializations. Have a look at the "opt" source code. On 02/12/13 10:36,

Hello, I am new to LLVM so apologies for a possibly basic question. I am trying to autopartition some codes into pieces so that I can compile these pieces with different backends. My idea is to create one module per desired piece, and transfer the functions from the module I am visiting to these newly created modules, deleting the function in the previous module and adding it to the new one.

I can't reproduce this on x86-64 linux with latest LLVM+dragonegg+gcc-4.6. ¿Should I > post it somewhere else in case it's really a bug? Thanks ahead! > > With this simple program: > * > #include

I am working on a pass to extract small regions of code to run somewhere else (different node in a cluster). Basically what I need is the ability to isolate a region of code, get its inputs and outputs, create a new function with the extracted code and code aggregating the in and out parameters as structs that can be cast for a “void*”-based interface. It looks like the CodeExtractor

Hi all, I have a code with three passes (one loop pass and two module passes) and my own pass manager. If I schedule the loop pass between the others, my code segfaults. Is there any explanation why loop passes cannot be scheduled between two module passes? Perhaps I misunderstood the behaviour of pass managers. I paste here my "usage" information: int main(...){ Module m = ...

The patch exits normally except for that error. The attached patch should apply cleanly. Thanks for the feedback,

Hi Pablo, I can reproduce this with the supplied IR. It is related to the use of __memcpy_chk. As far as I can see it is a bug in lli or the LLVM code generators. Can you please open a bugreport, attaching the LLVM IR. Ciao, Duncan. On 23/01/12 17:00, Pablo Barrio wrote: > Hi Duncan, >>> #include<stdio.h> >>> #include<string.h> >>> >>> int

Hi Pablo, in fact this is coming from the "ssp" attribute on main, which turns on LLVM's stack protection logic. I have no idea what that does exactly, but it seems to be causing the problem. On ubuntu systems it is enabled by default. You can turn it off by passing -fno-stack-protector to dragonegg. However please still open a bugreport since stack protection is supposed to work.

Hi Pablo, > I have a code with three passes (one loop pass and two module passes) > and my own pass manager. If I schedule the loop pass between the others, > my code segfaults. when developing with LLVM you should configure with --enable-assertions. That way you should get an assert failure with a helpful message rather than a crash. Is there any explanation why loop passes cannot
