[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] 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
