Hi Prathamesh,
It is my understanding that INTEGRAL_TYPE_P applies to the other
integer types you mentioned (chart, short, long). In fact the test
function that motivated this match has a mixture of char and short and
does not restrict matching.

This patches transforms ((x & 0x1) == 0) ? y : z y -into
(-(typeof(y))(x & 0x1) & z) y, where op is a '^' or a '|'. It also
transforms (cond (and (x , 0x1) != 0), (z op y), y ) into (-(and (x ,
0x1)) & z ) op y.
