Why is there no EmitInt64 in AsmPrinter?
Hi all,
The AsmPrinter class supports functions like EmitInt8, EmitInt16, and
EmitInt32 for writing a 1/2/4 byte directive to the assembly. Each of these
calls the MCStreamer::EmitIntValue method with the corresponding size. For
some reason, there is no EmitInt64, and I was wondering if there was a
fundamental reason why? The EmitIntValue function appears to support 8-byte
inputs.
I dug into this a bit more and found a commit way back in 2010 (r100296)
that removed the "EmitInt64" equivalent, with no explanation (presumably it
was unused).

[LLVMdev] JIT buffer code skipping 8 bytes?
...ses which did not seem match the excepted type info offset. In truth I'm
not sure what a type info is anyway, as I know they are not c++ type infos, but the array trick seems to work ... sort of. My question
though is:
1) In JITDwarfEmitter.cpp these GlobalVariables are emitted with:
JCE->emitInt64((intptr_t)Jit.getOrEmitGlobalVariable(GV));
(in JITDwarfEmitter::EmitExceptionTable)
2) The allocated emitted space is calculated by:
JITCodeEmitter::allocateSpace(...) as eventually called by getOrEmitGlobalVariable(...)
3) If the correctly sized buffer was already allocated, and alignment did...

[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

[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
