An upstream Rust bug notes notes that the Python pretty-printing feature is broken for values that appear as members of certain types in Rust. The bug here is that some of the Rust value-printing code calls value_print_inner, a method on rust_language. This bypasses the common code that calls into Python. I'm checking this in. gdb/ChangeLog 2021-05-14 Tom Tromey <tom@tromey.com> * rust-lang.c (rust_language::val_print_struct) (rust_language::print_enum): Use common_val_print, not value_print_inner. gdb/testsuite/ChangeLog 2021-05-14 Tom Tromey <tom@tromey.com> * gdb.rust/pp.exp: New file. * gdb.rust/pp.py: New file. * gdb.rust/pp.rs: New file.
