[llvm-dev] LLVM-IR: order of a PHI node predecessors ?

[Jeroen Dobbelaere via llvm-dev]

Hi all,

are there any restrictions on the order of a PHI node predecessors ?

Like following example, is this still valid LLVM-IR ?

---
for.body:                                         ; preds = %for.body, %entry
  %lsr.iv43 = phi i32 [ %lsr.iv.next44, %for.body ], [ 0, %entry ]
  %i.032 = phi i32 [ 0, %entry ], [ %inc, %for.body ]                           ; %entry and %for.body reversed
