;; Date: May 28, 2003.

|
;; From: test/Programs/External/SPEC/CINT2000/254.gap.llvm.bc
|
|
;; Function: int %OpenOutput(sbyte* %filename.1)
|
|
;;
|
|
;; Error: A sequence of GEPs is folded incorrectly by llc during selection
|
|
;; causing an assertion about a dynamic casting error.
|
|
;; This code sequence was produced (correctly) by preselection
|
|
;; from a nested pair of ConstantExpr getelementptrs.
|
|
;; The code below is the output of preselection.
|
|
;; The original ConstantExprs are included in a comment.
|
|
;;
|
|
;; Cause: FoldGetElemChain() was inserting an extra leading 0 even though
|
|
;; the first instruction in the sequence contributes no indices.
|
|
;; The next instruction contributes a leading non-zero so another
|
|
;; zero should not be added before it!
