2017-02-02Use bool in Rust codeTom Tromey1-6/+6
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): Return bool.
2017-02-02Use std::string in Rust codeTom Tromey1-4/+3
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.
2017-01-01update copyright year range in GDB filesJoel Brobecker1-1/+1
This applies the second part of GDB's End of Year Procedure, which updates the copyright year range in all of GDB's files. gdb/ChangeLog: Update copyright year range in all GDB files.
2016-11-12Remove some cleanups from the rust codeTom Tromey1-58/+36
This removes some cleanups from the rust code, in favor of C++ objects with destructors. 2016-11-12 Tom Tromey <tom@tromey.com> * rust-exp.y (super_name): Use std::vector. (lex_number): Use std::string. (convert_params_to_types): Return std::vector. (convert_ast_to_type, convert_name): Update. * rust-lang.c (rust_get_disr_info): Use unique_xmalloc_ptr.
2016-11-08Use ui_file_as_string throughout morePedro Alves1-7/+4
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. gdb/ChangeLog: 2016-11-08 Pedro Alves <palves@redhat.com> * ada-lang.c (ada_name_for_lookup, type_as_string): Use and return std::string.

2016-07-21Allow empty struct expressions in RustTom Tromey1-3/+7
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.
2016-07-14Remove unused variablesTom Tromey1-3/+1

2016-06-10Fix PR rust/20110Tom Tromey1-2/+13
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.
