similar to: 64 bit mask in x86vshuffle instruction

i want to emit binary code for the following implemented vector assembly instructions. P_256B_LOAD_DWORD R_0_R2048b_0, pword ptr [rip + b] P_256B_LOAD_DWORD R_0_R2048b_1, pword ptr [rip + c] P_256B_VADD R_0_R2048b_0, R_0_R2048b_1, R_0_R2048b_0 P_256B_STORE_DWORD pword ptr [rip + a], R_0_R2048b_0 I added the following lines in X86MCInstLower.cpp; unsigned NewOpc; switch (OutMI.getOpcode())

Hello, i want to work with these types v32f32, v32f64.... in llvm which are undefined in the backend? But v32i32, v32i64 are already defined so i am able to use these. but for other types such as v32f32, v32f64 although i have defined them appropriately in all the files like machinevaluetype.h, valuetypes.cpp etc. i have checked it many times but still getting the following error when build in

Thank you so much. it run fine. Can you please resolve following issue; I now have support for v2048i32 but my backend supports v64i32 so ultimately v2048i32 needs to be split into 32 v64i32 instructions. the only difference between 2 is if its orginally v2048i32 i want my registers assignment from REG_A set. if its v64i32 originally, then i want registers from set REG_B. How to accomplish

I would be very grateful if you specify whether there is some way to allocate registers (different order) / from different register sets to the same instruction based on the vector width/ no of iterations. I have tried several alternatives but could not succeed. Also I have asked this question many times but no one responds. Is there something wrong with this?? Kindly guide me. Thank You On

Hello. I wanted to inform that I fixed the bug from the previous email. The main reason for the bug was that I thought that the SDNode masked_gather is returning only 1 value, but it returns 2 (hence, I guess, the earlier reported, difficult to follow, error: "Assertion `New->getNumTypes() == 1"). masked_gather returns 2 values because: // SDTypeProfile -

Hello. I fixed the bug reported in the previous post on this thread (<<llvm::MemSDNode::MemSDNode(unsigned int, unsigned int, const llvm::DebugLoc&, llvm::SDVTList, llvm::EVT, llvm::MachineMemOperand*): Assertion `memvt.getStoreSize() <= MMO->getSize() && "Size mismatch!"' failed.>>) The problem with this strange error reported comes from

Hello. Will, thanks a lot for pointing me to the MaskedGatherSDNode and mgatherv4i32. I have to say that the definition of the "multiclass avx512_gather" from lib/Target/X86/X86InstrAVX512.td is difficult to follow and I prefer not to use it. I currently have some serious problems with TableGen - it gives an assertion failure:
