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

Thx again Evan for the review. Here's a new patch for the JIT in itself. The major changes are: 1) A JITMemoryManager now has a flag saying "I require to know the size of what you want to emit" 2) DwarfJITEmitter is augmented with GetSize* functions 3) JITEmitter::startFunction checks if the JITMemoryManager requires to know the size. If so, it computes it and gives it through the ActualPtr argument. I suppose it's OK to commit, but if anyone wants to complain, I'm listening :) Thanks, Nicola...
