From 73fc52c4ccecf005aac264e3faa08e815d25118a Mon Sep 17 00:00:00 2001 From: Tom Tromey Date: Fri, 16 Nov 2018 15:30:35 -0700 Subject: Handle TYPE_CODE_PTR when printing Rust types This changes the Rust type printers to handle TYPE_CODE_PTR. The current approach is not ideal, because currently the code can't distinguish between mut and const, or between pointers and references. (These are debuginfo deficiencies, for which there are rustc bugs on file.) Meanwhile, this at least clears up the case seen in PR rust/23625. Tested on x86-64 Fedora 28. The nightly compiler gives the best results, but I regression-tested with stable and beta as well. gdb/ChangeLog 2018-11-16 Tom Tromey PR rust/23625: * rust-lang.c (rust_internal_print_type): Handle TYPE_CODE_PTR. gdb/testsuite/ChangeLog 2018-11-19 Tom Tromey PR rust/23625: * gdb.rust/simple.exp: Add ptype test.
