[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

[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). Nicolas -------------- next part -------------- An embedded and charset-unspecified text was scrubbed... Name: jit-exceptions.patch URL:
