Tom Tromey 12df5c002d Allow empty struct expressions in Rust
I learned recently that empty struct expressions, like "X{}", have been
promoted from experimental to stable in Rust.  This patch changes the
Rust expression parser to allow this case.

New test case included.
Built and regtested on x86-64 Fedora 23, using Rust 1.11 beta.

2016-07-21  Tom Tromey  <tom@tromey.com>

	* rust-lang.c (rust_tuple_struct_type_p): Return false for empty
	structs.
	* rust-exp.y (struct_expr_list): Allow empty elements.

2016-07-21  Tom Tromey  <tom@tromey.com>

	* gdb.rust/simple.rs (main): Use empty struct expression.
	* gdb.rust/simple.exp: Add tests for empty struct expression.

Tom Tromey 347dc1025d Fix PR rust/20110
PR rust/20110 concerns the type of an integer constant that is too
large for "i32", the default integer type.  This patch changes the
type of such a constant to i64.  This is important because such values
are often addresses, so truncating them by default is unfriendly.

Built and regtested on x86-64 Fedora 23.

2016-06-10  Tom Tromey  <tom@tromey.com>

	PR rust/20110:
	* rust-exp.y (lex_number): Don't truncate large numbers to i32.

2016-06-10  Tom Tromey  <tom@tromey.com>

	PR rust/20110:
	* gdb.rust/expr.exp: Add test for integer constant larger than
	i32.
