Dear all, Here's a new patch with Evan's comments (thx Evan!) and some cleanups. Now the (duplicated) exception handling code is in a new file: lib/ExecutionEngine/JIT/JITDwarfEmitter. This patch should work on linux/x86 and linux/ppc (tested). Nicolas -------------- next part -------------- An embedded and charset-unspecified text was scrubbed... Name: jit-exceptions.patch URL:

Hi everyone, Here's a patch that enables exception handling when jitting. I've copy/pasted _many_code from lib/Codegen/DwarfWriter.cpp, so we may need to factorize it, but the functionality is there and I'm very happy with it :) lli should now be able to execute the output from llvm-gcc when using exceptions (the UnwindInst instruction is not involved in this patch). Just add the

Hi everyone, vmkit requires to know the size of a jitted method before emitting the method. This allows to allocate the correct size for the method. The attached patch creates this functionality when the flag SizedMemoryCode is on. In order to implement this functionality, i had to virtualize some MachineCodeEmitter functions. Is it OK to commit the patch? Thanks, Nicolas --------------

Hi, I'm working on bringing up complete coverage for a Gentoo x32 "desktop" system. I've been cooking up quite a few patches for various packages to push upstream, but right now, the biggest blocker is the lack of support for building with/codegen targeting x32 in llvm/clang. Since the x32 patches were sent last year, I see support code has landed in LLVM, and basic handling of
