Awesome! What will the requirements be for the target? Is it sufficient to just override getPointerTy and add appropriate data layout strings, or will more hooks be needed?

Looking through recent additions, it looks like the infrastructure exists for targets to specify a per-address-space pointer size/type, but this does not seem to be used anywhere (SelectionDAGBuilder, legalizer, etc.). What is the status of this support? Is anyone actively working on it? -- Thanks, Justin Holewinski -------------- next part -------------- An HTML attachment was scrubbed...

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:

Dear Prof. Adve, I recently checked out the llvm using cvs update command under the llvm directory. But when I went to see the DSNode.h, there is no getPointerSize function. I checked the doxygen tree, it's there. So that means I didn't update my cvs tree correctly. Could you let me know how to update my CVS tree? Or there is a problem at somewhere else?

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
