RKSimon added inline comments.
================
Comment at: llvm/test/CodeGen/X86/select_const.ll:204
; If the constants differ by a small multiplier, use LEA.
; select Cond, C1, C2 --> add (mul (zext Cond), C1-C2), C2 --> LEA C2(Cond * (C1-C2))
----------------
Comment doesn't match select_lea_2 (but the others are still OK).
