[LLVMdev] Being able to know the jitted code-size before emitting
Hi everyone,
vmkit requires to know the size of a jitted method before emitting the
method. This allows to allocate the correct size for the method. The
attached patch creates this functionality when the flag SizedMemoryCode
is on.
In order to implement this functionality, i had to virtualize some
MachineCodeEmitter functions.
Is it OK to commit the patch?
Thanks,
Nicolas

[LLVMdev] PowerPC instruction cache invalidation
Hi all,
When you genetate code on PowerPC you need to explicitly invalidate
the instruction cache to force the processor to reread it. In LLVM
there is code to do this for function stubs on Macintosh, but not
for other platforms and not for JITted code generally.
The attached patch adds support for GNU platforms, but I can't figure
out a nice way to call it for all generated code. Can

[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] 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).
