I am testing vectorization on the following test case: float x[1024], y[1024]; void myloop1() { for (long int k = 0; k < 512; k++) { x[2*k] = x[2*k]+y[k]; } } Vectorization failed due to "unsafe dependent memory operation". I traced the LoopAccessAnalysis.cpp and found the reason is the NoWrapFlag for SCEVAddRecExpr is not set and consequently the

Hi Adam, > One problem, I was trying to solve was, that I need to declare variables of let's say 5-bit width like 'i5 var', > the maximal bit-width may be limited to 64 bits. I need such variables to represent instruction's operands, > example is at the end this message. any standard compliant C compiler supports i5, believe it or not. Try this: #include

Hi everyone, I am trying to write a pass, that finds some instructions and replaces them with my intrinsics, but I am having problem understanding, how this should be done. Let's say I have this instruction: %tmp14 = load i32* getelementptr ([32 x i32]* @gpregs, i32 0, i64 28) and i need to read the load's operands and replace it by let's say: %tmp14 = call i32 @llvm.regread_i32.i32(i32 0, i32 1) Here is what I have: //for each instruction of a function for (inst_iterator I = inst_begin(F)...
