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

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:

Interesting. Was this the reason you were getting the recursive compilation error in JIT::runJITOnFunctionUnlocked(...) (isAlreadyCodeGenerating)? Do you have the time to try your test with 2.7?

I've worked around this issue in my test case by simply calling my personality function on program to ensure it's JIT'ed before any unwind happens. -- James 2010/1/22 Garrison Venn <gvenn.cfe.dev at gmail.com> > No, there is no magic. :-) > > To me though, the tools are magic, because I have no clue what they are > doing without looking at them and using them. >
