3 ;; GetMemInstArgs() folded the two getElementPtr instructions together,
4 ;; producing an illegal getElementPtr. That's because the type generated
5 ;; by the last index for the first one is a structure field, not an array
6 ;; element, and the second one indexes off that structure field.
7 ;; The code is legal but not type-safe and the two GEPs should not be folded.
9 ;; This code fragment is from Spec/CINT2000/197.parser/197.parser.bc,
10 ;; file post_process.c, function build_domain().
11 ;; (Modified to replace store with load and return load value.)
