...(INST_OUT (INST_IN), REG:$r1)>; where INST_IN doesn't accepts any inputs and INST_OUT accepts two inputs - one returned by INST_IN and REG;$r1. Is there any possibility to ‘Glue’ two instruction created in a such way? Maybe something similar to creation SDNodes with SDNPOutGlue, SDNPInGlue) ? These two instructions INST_IN and INST_OUT have to be one after another without any other inserted between them.

...nly the immediate result can be directly used, otherwise, several noops need to be inserted.) As the result generated by the binary operation is stored in an implicit forwarding register and flushed every cycle, I need to stick AND and MULADDFWD instructions together. I can use a custom node with SDNPInGlue property to select MULADDFWD, but how can I make the binary operation output a glue, so that I use the glue to stick them together? This may be confusing, but I work in a not-so-normal target. Look forward to your reply. Best wishes Peng Wang -------------- next part -------------- An HTML attach...

...ue. 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; // Read a flag operand def SDNPOptInGlue : SDNodeProperty; // Optionally read a flag operand

Hello everyone, I wanted to attach a node without affecting the present nodes in any way. I tried to use MVT::Glue for that but I think I'm missing something as I could not achieve the below state. LUI LUI | | ADDI ----GLUE---- ADDI | store I've few question about this and Glue node in general, I'll be happy to get some help on
