My output shows the 'Pass Arguments:' line has automatically added -targetpassconfig -verify -writebitcode, and the -targetlibinfo flag was moved to the start. Is there a way I can address these differences to enable replicating the -O3 first and second passes using opt flags?

Hi, I try to use MemoryDependenceAnalysis in a pass to analyse a simple function: void fct (int *restrict*restrict M, int *restrict*restrict L) { S1: M[1][1] = 1; S2: L[2][2] = 2; } When I iterate over MemoryDependenceAnalysis on the S2 statement, I get the load instruction for the first depth of the array, that’s ok. But I get also the load and store for the S1 statement. I assume the
