Hi Assuming I had an application stub based on (say) lli, and I'd like to allow a hypothetical IDE to recompile and relink a function: Is that supported in any way currently? Assuming actually patching all call sites to point to the newly generated function is possible, I guess what I need is to be able to either track or find all of the call sites. The trickiest bit seems to be if the

Couldn’t you write the relocations to the ELF executable? I don’t know if current linkers have support for this, but it seems possible in theory to make a relinkable executable. If you want to do this with an already linked executable though, then yea this won’t be possible.

...but it could make moving functions really cheap). a more selective way of doing this would be helpful (for example, a special compiler-specific keyword, or some other approach for telling the VM/linker that a particular function is movable). this would probably one-off the function, by forcibly relinking it as a proxy to the function (any future attempts at relinking the function then simply adjust its associated pointer). potentially, this could also be made the default behavior for when relinking functions (if they are being forcibly relinked, well, assume they are being made movable). or such....

Hi, Let's suppose we have an ELF executable that doesn't issue any syscall (I mean, syscalls are issued from an external dynamic library, not from the executable, and we can ignore such dynamic library because we have the proper equivalent library with the proper syscalls in MacOS and Windows). So, the question: Is it "currently possible" (by "currently possible" I

LLVM, When we recompile, is it possible to "make" only one of the tools, or at least relink only the tools whose object files have changed? Thanks Dave

I don't remember having any trouble building the plugin on my ibook but that was a few months ago, so my memory may be fuzzy.

Hi Charllls, I didn't really get it. Are you saying that you would execute some functions using the JIT then, later, those functions will be modified and thus need to be re-jitted? Ciao, Duncan.

I'm trying to get R running on OpenBSD/alpha. I've applied some configure patches which I've previously sent to the R-devel list to allow R to compile on an OpenBSD ELF platform (which OpenBSD/alpha is, as the i386 port soon will be). The patched source compiles without problems, and appears to run and perform properly apart from two (possibly unrelated) problems. 1) On startup

Hi, JIT does not allow functions to call others in different modules, so all modules need to be statically linked in a big fat module. If a module needs to be recompiled, all the others need to as well as relinked. there are two ways i intend to approach this problem: 1) forget about JITing, build each module into a .bc, call gcc to generate .soname libraries, dynamically load with dlopen()
