Tom Tromey 65c40c956f Use bool in Rust code
This changes various functions in the Rust code to use a bool rather
than an int when a boolean is intended.

2017-02-02  Tom Tromey  <tom@tromey.com>

	* rust-exp.y (ends_raw_string, space_then_number)
	(rust_identifier_start_p): Return bool.
	* rust-lang.c (rust_tuple_type_p, rust_underscore_fields)
	(rust_tuple_struct_type_p, rust_tuple_variant_type_p)
	(rust_slice_type_p, rust_range_type_p, rust_u8_type_p)
	(rust_chartype_p): Return bool.
	(val_print_struct, rust_print_struct_def, rust_print_type):
	Update.
	* rust-lang.h (rust_tuple_type_p, rust_tuple_struct_type_p):

Tom Tromey 03c85b11b0 Use std::string in Rust code
This changes a couple of spots in the Rust support to use std::string.
In one spot this removes some manual memory management; in the other
spot this allows the removal of a call to xstrdup.

2017-02-02  Tom Tromey  <tom@tromey.com>

	* rust-lang.h (rust_crate_for_block): Update.
	* rust-lang.c (rust_crate_for_block): Return std::string.
	(rust_get_disr_info): Use std:;string, not
	gdb::unique_xmalloc_ptr.
	* rust-exp.y (crate_name): Update.

This removes some cleanups from the rust code, in favor of C++ objects
with destructors.

Pedro Alves 2f408ecb92 Use ui_file_as_string throughout more
This replaces most of the remaining ui_file_xstrdup calls with
ui_file_as_string calls.  Whenever a call was replaced, that led to a
cascade of other necessary adjustments throughout, to make the code
use std::string instead of raw pointers.  And then whenever I added a
std::string as member of a struct, I needed to adjust
allocation/destruction of said struct to use new/delete instead of
xmalloc/xfree.

The stopping point was once gdb built again.  These doesn't seem to be
a way to reasonably split this out further.

Maybe-not-obvious changes:

 - demangle_for_lookup returns a cleanup today.  To get rid of that,
   and avoid unnecessary string dupping/copying, this introduces a
   demangle_result_storage type that the caller instantiates and
   passes to demangle_for_lookup.

 - Many methods returned a "char *" to indicate that the caller owns
   the memory and must free it.  Those are switched to return a
   std::string instead.  Methods that return a "view" into some
   internal string return a "const char *" instead.  I.e., we only
   copy/allocate when necessary.

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.

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.

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