similar to: [LLVMdev] Is it correct for a glue operand to be replaced with a chain?

Hi, I'm not sure. But in your lowered DAG the chain nodes are the first operands for you custom nodes, however for the other nodes the chain is the last operand. I seem to remember that during targetlowering the chain is the first operand and then it seems to switch over after ISelDAG, this confused me and may have something to do with the issue that you are seeing. I really don't

Hi, I got that message from a call to InstrEmitter::AddOperand. I am writing a back end for CortexM0 (for self teaching purposes), I am working on LDR with immediate offset instruction. In the ARM backend, if the offset is 0, the following code is executed by the function ARMDAGToDAGISel::SelectThumbAddrModeImm5S Base = N.getOperand(0); OffImm = CurDAG->getTargetConstant(0, MVT::i32);

Hi, Yes, that's what I would do. If you want LLVM and the register allocator to also know that the instruction explicitly defines the register, I would designate the register into it's own register class and have your instruction write to that class (and there will be only a single option for RA). cheers, Sam Sam Parker Research Student Electronic Systems Design Group Loughborough

Hi Dmitri, If you have such a simple intrinsic which operates on a single register, just lower the intrinsic to a target specific node which is only implemented by a single instruction. Like you were doing before and by using a chain operand. Hard code the instruction to use and define the global register and only pass the instruction the actual variable argument. Hope that helps, Sam Sam

Thanks, I hadn't heard about PNaCl, it's very interesting. I'm currently swimming in http://llvm.org/docs/ trying to learn more about LLVM-IR...

Hi Jakob, If glue operands are used by the scheduler to keep instructions together, why can't the register allocator also do this?

Hi Anitha, memri is just describing that the address contains two components, an immediate and a register, and how to handle them in the instruction printer. The STWU expects a memri operand, and that is what is passed from the Pat. Hope that helps, Sam On 07/04/2013 10:19, Anitha B Gollamudi wrote: > Hi, > > > How do "Pat" operands get matched?

Hi, How do "Pat" operands get matched? I am trying to follow the example given in http://llvm.org/docs/CodeGenerator.html#selectiondag-process In the latest trunk of ppcintrinfo.td following pattern is defined: def : Pat<(pre_store i32:$rS, iPTR:$ptrreg, iaddroff:$ptroff), (STWU $rS, iaddroff:$ptroff, $ptrreg)>; I understand that input operand list i.e. ins of

Hello Erwan and others, I am running HDT from grub2 with memdisk. I have informed the success of booting hdt to the grub2 list. Some developers are very much interested to this issue and they are showing their interest to make a glue between com32 and grub2 so that hdt can be loaded without memdisk. It is really very exciting to have hdt as an inbuilt feature of grub2. Could any one kindly

Hi Folks, I am just starting to get familiar with the llvm framework, thank you at first for this nice tool which seems really powerful! I have studied so far the Kaleidoscope example and other docs at llvm.org and try to figure out which would be the "right" way (well I suppose there are many) to integrate the framework into my compiler project, but there is still quite a gap between

My understand is that in DAG terminology, Flag is now called Glue. It would be nice for someone to go through and clean up the code as far as comments and variable names. That was driving me close to the brink of insanity till I found out about this. Even in Selection Dag Node Properties def SDNPOutGlue : SDNodeProperty; // Write a flag result def SDNPInGlue : SDNodeProperty;
