[PATCH] D65118: Analysis: Don't look through aliases when simplifying GEPs.

[Puyan Lotfi via Phabricator via llvm-commits]

plotfi added a comment.

I'm seeing a lit failure for gep-alias.ll on my end (Fedora 64bit). The output is:

  $ /home/plotfi/Projects/llvm-project/build/bin/opt -instcombine -S -o - /home/plotfi/Projects/llvm-project/llvm/test/Analysis/ConstantFolding/gep-alias.ll
  ; ModuleID = '/home/plotfi/Projects/llvm-project/llvm/test/Analysis/ConstantFolding/gep-alias.ll'
  source_filename = "/home/plotfi/Projects/llvm-project/llvm/test/Analysis/ConstantFolding/gep-alias.ll"
  target datalayout = "e-m:e-i64:64-f80:128-n8:16:32:64-S128"
  target triple = "x86_64-unknown-linux-gnu"
  
  @a = internal global [3 x i8*] zeroinitializer
  
  @b = linkonce_odr alias [3 x i8*], [3 x i8*]* @a
  
  define i8** @f() {
    ret i8** getelementptr ([3 x i8*], [3 x i8*]* @b, i64 0, i64 1)
  }

But you do a check for " ; CHECK: ret i8** getelementptr ([3 x i8*], [3 x i8*]* @b, i32 0, i32 1)" This seems odd.
