Also, instead of testing for XEXP(SET_SRC(PATTERN(i3)),1) == const0_rtx at the top, it now allows CONST_INT_P(XEXP(SET_SRC(PATTERN(i3)),1)), tries to adjust it by simplify_compare_const() from the last patch, and then tests if op1 == const0_rtx. This is a small improvement in some cases.
I'm not sure why it doesn't allow both? Paolo
