        PR c++/37004
cp/
        * typeck.c (cp_common_type): New. The same as
        type_after_usual_arithmetic_conversions but without promotions.
        (type_after_usual_arithmetic_conversions): Do the promotions and
        call cp_common_type.
        (common_type): Make it behave like the C version of this
        function. Do not handle pointer types.
        (common_pointer_type): Move handling of pointer types from
        common_type to here.
        (cp_build_binary_op): Use common_pointer_type instead of
        common_type in call to pointer_diff.
        Use cp_common_type instead of common_type.
        * cp-tree.h (common_pointer_type): Declare.
testsuite/
        * g++.dg/warn/Wconversion-pr34389.C: Remove XFAIL.
