similar to: [LLVMdev] Re: a linking problem of LLVM

gccld passes -shared through if it's generating a shared library, but if you're compiling a program that needs to have its symbols externally accessible, it doesn't pass -export-dynamic through to gcc for the final link. The attached patch fixes this. I've tested with a small test case I sent Chris, and with Python; both seem to work. I also fixed some inaccurate comments in

Hi Shuo, I am CCing your questions to the LLVM developers list so others can reply or correct me. >I have a few questions about LLVM: >(1) The LLVM tutorial says LLVM can be used in architecture research.

I recently realized that I haven't sent out a status update for the LLVM core components quite a while, so here is a new one: We've been really busy working on LLVM adding all kinds of new features, fixing lots of bugs, and are rapidly converging on our 1.0 release for this August. Here are some of the new features added recently: 1. Support for static constructors/destructors in

Hello everybody, I'm developing a source code transformation system for real-time systems currently, i.e. I want to map the application (a set of event handlers) to a run-time or operating system semi-automatically (if anybody is interested in the background - see below, of course, comments are welcome there, too ;-)). Therefore, I have to be able to express dependencies between different

Bram, I looked over your patch and it looks good. I applied a patch based on yours. The llvm-ld tool now uses the PluginLoader just like the opt tool. It will also run some cleanup passes after the loaded plugins run to ensure cruft is removed. See this patch for details: http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20060814/036882.html Thanks for the patch! And, yes, you are on

Hi Everyone, Sorry for the long overdue status update, as you might guess, the holidays have been busy for everyone. :) Here's your periodic dose of updates on the progress of LLVM, which takes us from the LLVM 1.4 release until present CVS. I appologize if I forgot anything! Big Things: 1. Brian contributed a new SparcV8 backend, which (unlike the SparcV9 backend) uses the

Hi, i used CVS to checkout the source of llvm and llvm-gcc, compiled and built them on my machine successfully. i tried a c-language hello program, it was OK. But when i tried a c++-language hello program, i got: ~/project/llvm/examples$ llvm-g++ t3.cc -o t3 gccld: /developer/zsth/project/llvm/src/llvm/lib/Analysis/IPA/CallGraph.cpp:277: void

We have a research project that is developing a Secure Virtual Architecture using LLVM as the instruction set, and implementing via a VM which we call a Secure Virtual Machine. The memory safety foundations of this work are based on Dinakar Dhurjati's thesis and publications: http://llvm.org/pubs/ SVA is at a very preliminary stage but some slides about it are attached.

Hi, Sean: I'm sorry I lie. I didn't mean to lie. I did try to avoid making a *BIG* change to the IPO pass-ordering for now. However, when I make a minor change to populateLTOPassManager() by separating module-pass and non-module-passes, I saw quite a few performance difference, most of them are degradations. Attacking these degradations one by one in a piecemeal manner is wasting

hi, I'm really new to llvm. I've successfully bootstrapped llvm-14 on my system and am able to successfully compile c code to llvm. the problem is now that gccld is complaining that it can't find the libraries, like "c" or "crtend". [1] all is fine, if I just use intrinsified functions like printf and friends, but I want to use the clock_gettime function and
