You can run SCEV which will see through bitcasts and GEPs, so it should give an expression of the form (base + offset) on the pointer of the load.

Hi, Below is the snippet of LLVM IR code generated by Flang ---snip-- %3 = getelementptr i64, i64* %"a$sd", i64 11, !dbg !16 %4 = bitcast i64* %3 to i32*, !dbg !16 %5 = load i32, i32* %4, align 4, !dbg !16, !tbaa !22 ---snip-- My requirement is for any such LoadInst (example: %5), I want to check if its base GEP (i.e. %3) loads at particular offset (11) from its corresponding
