This is a template that takes care of managing plugin registries. I wrote it because I got the distinct feeling I was needlessly reinventing the wheel as I wrote a collector registry. I haven't converted anything else to use it, though. Still, it's orthogonal and has become stable in my usage, so I thought I'd submit it in advance. To get my collector registry going, all I

Hi all, In order to support linking AsmWriter separately from CodeGen, the Collector class (a CodeGen component) had to be decoupled from the AsmWriter interface. This required moving the beginAssembly and endAssembly methods to a separate abstract base class. If you had overridden these methods, your class may compile successfully but fail at runtime with a message of the form:

Hello all, Relevant info up front: Gentoo PC, using 2.6.38 kernel and Samba 3.4.12. I'm trying to get a FreeRadius instance working for our Windows network. To do so, I need a Linux box running Samba. I've installed and configured Kerberos, Samba and FreeRadius, and can get most things to work. I can get a Kerberos key using kinit, and "sudo net ads keytab list" shows me

Thanks for the review Gordon.

Hi, Long time ago (llvm-svn june 2008) I asked here about a way to output the assembly code of my JIT generated code to a string, so I could use it to read it on the screen. I came up with this solution: std::string Err; const llvm::TargetMachineRegistry::entry* _arch = llvm::TargetMachineRegistry::getClosestTargetForJIT(Err); std::string FeaturesStr; llvm::TargetMachine*

Thank you so much for your help! I now have a much clearer idea of how to proceed. :-) This just keeps getting more interesting. - Simon 2008/7/26 Gordon Henriksen <gordonhenriksen at me.com>: > On Jul 26, 2008, at 12:14, Simon Ask Ulsnes wrote: > > 2008/7/26 Gordon Henriksen <gordonhenriksen at me.com>: > > I'm not sure the purpose of doing so—llvm::Collector

Well, I've been before hours trying this, but soon after I sent the email I found something. However is quite intriguing. I just changed the order of and the static libraries that I was linking. How can this be possible?? I'm using Cmake for building my llvm projects, so I choose the order and I pick the .a libraries I want to link by hand... Thank you, alvaro 2009/3/8 Álvaro

Hello, I'm trying to catch assembly output and do some formatting for its presentation while being executed. I face a problem, which is clear from the error, although I have no clue on how to do it otherwise. If generating the code for its asm output and then for jit execution I get: ********** static llvm::MachineFunction& llvm::MachineFunction::construct(const llvm::Function*, const

When you say 'static libraries' do you mean static libraries or shared objects (.so)... Because if you mean shared objects, then it could very well explain you crash.
