[LLVMdev] Being able to know the jitted code-size before emitting
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

[LLVMdev] Exception handling in JIT
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).

[LLVMdev] Exception handling in JIT
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
