[LLVMdev] MBlaze select_cc lowering question.
Can someone explain how the condition code is passed from the
MBlazeTargetLowering::LowerSELECT_CC to
MBlazeTargetLowering::EmitCustomSelect custom inserter? In
LowerSELECT_CC the condition code is never accessed (Op.GetOperand(4))
and I don't see how it ends up getting correctly passed to the
MBlazeTargetLowering::EmitCustomSelect.

[LLVMdev] [patch] MicroBlaze Backend
...neric through your back end? That should give you some more test cases.
Some "feature" tests can be found inside other directories as well,
e.g. msp430 / systemz.
Are you planning to add microblaze description to clang? C compiler
can speed up testing alot :)

Do you really need this? Expanding dynamic allocas normally ends with
stack register adjustment, you don't need anything special here.

I already have a microblaze description in clang but I have not tested it as much so I have not submitted a patch for it yet.

I was unsure as to whether I needed this or not. I have been taking the appr...

[LLVMdev] mblaze backend: unreachable executed
Hi Josef,
> Okay, I've done a lot more testing and I now have a .bc file that compiles for x86, sparc, mips but refuses to compile for the mblaze and powerPC backends because of the calling convention. Is there anyone that would know how to fix the microblaze calling convention or point me in the right direction on how to fix it?
what does "refuses to compile" mean? I.e. what

[LLVMdev] [patch] MicroBlaze Backend
I have been working on a LLVM backend for the MicroBlaze soft-processor:
http://www.xilinx.com/tools/microblaze.htm
http://en.wikipedia.org/wiki/MicroBlaze
Attached is the initial MicroBlaze patch. It does the following:
1. Adds mblaze as a target in configure and configure.ac
2. Adds mblaze specific intrinsics in include/llvm/IntrinsicsMBlaze.td and include/llvm/Intrinsics.td
3. Adds mblaze

[LLVMdev] Problem using a label to a MachineBasicBlock
Can you please post the code to split a MachineBasicBlock?
I am trying to split a MachineBasicBlock at a specific instruction in the
MBB, let us say, into MBB1 and MBB2. This instruction should go into MBB2.
Also MBB1 should have an unconditional branch to MBB2 as the terminator.
(quite similar to splitBasicBlock in BasicBlock.cpp)
Meanwhile, I am trying to come up with a variant of
