[llvm-dev] Help on finding Base GEP

[Venkataramanan Kumar via llvm-dev]

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 arrays descriptor structure (a$sd).

is there any API in LLVM to check this? or I need to write my own?

regards,
Venkat.
