This patch implements Rust raw identifiers in the lexer in gdb. There was an earlier patch to do this, but the contributor didn't reply to my email asking whether he had sorted out his copyright assignment. This is relatively straightforward, but a small test suite addition was needd to ensure that the new test is skipped on older versions of rustc -- ones that predate the introduction of raw identifiers. gdb/ChangeLog 2021-06-11 Tom Tromey <tom@tromey.com> PR rust/23427 * rust-parse.c (rust_parser::lex_identifier): Handle raw identifiers. (rust_lex_tests): Add raw identifier tests. gdb/testsuite/ChangeLog 2021-06-11 Tom Tromey <tom@tromey.com> PR rust/23427 * lib/rust-support.exp (rust_compiler_version): New caching proc. * gdb.rust/rawids.exp: New file. * gdb.rust/rawids.rs: New file.
