There is no need to post such notices to gcc-patches, we have the gcc-cvs
mailing list where this is automatically posted to.
On gcc-patches it just adds unnecessary noise.

Hello,
this patch adds to fold_binary_loc some missing optimization for binary
and operations on truth-not expressions.
Added cases are:
(!X & X) is always zero.
(X & !X) is always zero.
(X == 0) & X is always zero.
X & (X == 0) is always zero.
!X & 1 is X == 0
