* varasm.c (get_pool_constant_mark): New.

* dwarf2out.c (mem_loc_descriptor): A pool constant cannot
be represented if it has not been output.

* combine.c (do_SUBST): Sanity check substitutions of
CONST_INTs, and reject them in SUBREGs and ZERO_EXTENDs.
(subst): Simplify SUBREG or ZERO_EXTEND instead of SUBSTing a
CONST_INT into its operand.
(known_cond): Likewise, for ZERO_EXTEND.
* simplify-rtx.c (simplify_unary_operation): Fix condition to
allow for simplification of wide modes. Reject CONST_INTs in
ZERO_EXTEND when their actual mode is not given.

* tree.c (host_integerp): Ensure that the constant integer is
representable in a HOST_WIDE_INT or an unsigned HOST_WIDE_INT
when pos is zero or non-zero respectively. Clarify comment.
* c-format.c (check_format_info_recurse): Fix host_integerp
usage; the pos argument should be zero when assigning to a
signed HOST_WIDE_INT.
* gcc.dg/20020219-1.c: New test.

* config/i386/i386.c (ix86_expand_vector_move): Use the mode
of the operand, rather than assuming TImode.

using nonimmediate_operand for both operands.

* java-tree.h: Update accordingly.
* expr.c (expand_invoke): Use build + check_for_builtin instead
of build_call_or_builtin.
* parse.y (patch_invoke): Likewise. This avoids needlessly creating
a new CALL_EXPR node, which means we don't lose the CALL_USING_SUPER
flag (which had caused jcf-write to incorrectly emit invokevirtual).
