Rust is adding raw identifiers in the 2018 edition: https://rust-lang-nursery.github.io/edition-guide/2018/transitioning/raw-identifiers.html The gdb lexer should implement this as well.
The master branch has been updated by Tom Tromey <tromey@sourceware.org>: https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;h=48ec4c05c68bfec4b79e95807bd82e0df4634a6c commit 48ec4c05c68bfec4b79e95807bd82e0df4634a6c Author: Tom Tromey <tom@tromey.com> Date: Fri Jun 11 08:14:09 2021 -0600 Implement Rust raw identifiers 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.

Fixed.
