Avoiding during my pass the optimization (copy propagation) of my LLVM IR code (at generation)
Hello.
I'm writing an LLVM pass that is working on LLVM IR.
To my surprise the following LLVM pass code generates optimized code - it does copy
propagation on it.
Value *vecShuffleOnePtr = Builder.CreateGEP(ptr_B, vecShuffleOne, "VectorGep");
...
packed_gather_params.push_back(vecShuffleOnePtr);
CallInst *callGather = Builder.CreateCall(func_llvm_masked_gather_v128i16,
packed_gather_params);
callGather->addAttribute(AttributeSet::FunctionIndex, Attri...

Strange opt error in Value ("replaceAllUses of value with new value of different type!" assertion failure)
Hello.
I'm getting the following error after adding some extra instrumentation in a module
(LoopVectorize.cpp ) due to a bug in Value::replaceAllUsesWith (see more comments of mine
below):
Value::replaceAllUsesWith(New = i16* inttoptr (i16 51 to i16*)), this =
%VectorGep = getelementptr i16, i16* inttoptr (i16 51 to i16*), <128 x i64>
zeroinitializer, !dbg !17 ; this output is generated by me to see why error happens
clang-3.9: /llvm/lib/IR/Value.cpp:380: void

It does *constant* propagation to be exact.

TableGen - Help to implement a form of gather/scatter operations for Mips MSA
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
