I want to generate the instruction like addi 40, r3 ! i.e. r3 = r3 + 40 The format i wrote is def ADDI : F1<opcode, (outs IntRegs:$dst), (ins IntRegs:$dst, i32imm:$imm) "addi $imm, $dst", [(set $IntRegs:$dst, (add $IntRegs:$dst, i32imm:$c))] but it is not compiling. what s...

Yeah at the end we need a representation for LUI and ADDI. We were trying to break the 64 bit address from GlobalAddress node into two i32 register. We will add custom load/store which will generate the address using values from two registers. We thought LUI an...

Instant fixes for the asm stuff: sed -i -e"s:;:\#:" on the lpc_asm.s to load address instead of addis+ori you could use lis and la and PLEASE use the @l(register) and @ha macros instead of the not gas supported hi/lo16(). eg: lis 31,LABEL@ha la 31,LABEL@l(31) append use -mregnames as as options (remove the other) (the option there isn't present in the as manual, and I could just try to...

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 this :) 1. Is Gluing the right approach or there is something better for such use case? 2. If I do something like DAG.getNode(ISD::ADDI, DL, MVT::Glue, LUINode, OtherADDINod...

[The below part is in reference with the RISCV LLVM backend] If there is no direct way to do this, we plan to fall back on a backup plan to convert the GlobalAddress node into the required LUI and ADDI pair but that would require the addition of two new target flag in RISCVII namespace. - Reshabh -------------- next part -------------- An HTML attachment was scrubbed...

Hi, I'm a beginner user using LLVM, and I'm trying to create a new backend using CPU0 Tutorial as reference. I have two instructions for add: add and addi (this is a pseudo instruction, but imediate operations is not available in architecture). That is my idea: When the LLVM instruction selection find addi r3 = r2 + value must convert to this: - load r1, value - add r3 = r2 + r1 In archInstrInfo.td I declared the instructions of the architecture,...

According to the wiki at voip-info.org, the dial structure for using oh323 without a gatekeeper is: OH323/<exten>@<host>:<port> or OH323/<exten> The second option is valid only in the case where a gatekeeper is used. NOTE: OpenH323 library v1.12.0 has a bug in the parsing of the destination host. When this version is used then the above syntax should be:

Hi Vikram, The error message would be helpful, but the most likely problem is the duplication of $dst. It should probably be: def ADDI : F1<opcode, (outs IntRegs:$dst), (ins IntRegs:$src, i32imm:$imm) "addi $imm, $dst", [(set $IntRegs:$dst, (add $IntRegs:$src, i32imm:$c))]> { let Constraints = "$src = $dst"; } i.e. separate registers, but a constraint noting...

Hi all, This is unusual for me to observe. I've a dhcp server running on Centos 5.3 and it takes a while to answer clients asking for an address. This is playing some havoc with certain scripts at startup not fully working because of the address delay. I've even used a dhcp helper address type function in my Juniper router but nothing has changed. Any ideas?

I am working on an experimental target and trying to make sure that the load offset field is used to the best way. There appears to be some control over the architecture's offset range and whether the offset is too large and needs to be lowered/converted into a separate sequence of operations in DAGSelection? Can someone point me to what might be the case? For example, the difference between
