483.xalancbmk retains this awesome constant expr until codegen:
%0 = load i16* getelementptr ([7 x i16]*
@_ZN11xercesc_2_5L17gIdeographicCharsE, i32 0, i32 add (i32 ashr (i32 sub (i32
ptrtoint (i16* getelementptr ([7 x i16]*
@_ZN11xercesc_2_5L17gIdeographicCharsE, i32 0, i32 4) to i32), i32 ptrtoint ([7
x i16]* @_ZN11xercesc_2_5L17gIdeographicCharsE to i32)), i32 1), i32 1)), align
4 ; <i16> [#uses=0]
This should get folded at the sub.
