PR ada/25875 concerns a gdb crash when gdb.ada/arr_enum_idx_w_gap.exp is run using the .debug_types board. The problem turns out to be caused by weird compiler output. In this test, the compiler emits a top-level type that refers to an enumeration type which is nested in a function. However, this function is just a declaration. This results in gdb calling read_enumeration_type for the enum type, but process_enumeration_scope is never called, yielding an enum with no fields. This causes the crash. This patch fixes the problem by arranging to create the enum fields in read_enumeration_type. Tested on x86-64 Fedora 30. gdb/ChangeLog 2020-04-29 Tom Tromey <tromey@adacore.com> PR ada/25875: * dwarf2/read.c (update_enumeration_type_from_children): Compute type fields here. (read_enumeration_type): Call update_enumeration_type_from_children later. Update comments. (process_enumeration_scope): Don't create type fields.
README for GNU development tools This directory contains various GNU compilers, assemblers, linkers, debuggers, etc., plus their support routines, definitions, and documentation. If you are receiving this as part of a GDB release, see the file gdb/README. If with a binutils release, see binutils/README; if with a libg++ release, see libg++/README, etc. That'll give you info about this package -- supported targets, how to use it, how to report bugs, etc. It is now possible to automatically configure and build a variety of tools with one command. To build all of the tools contained herein, run the ``configure'' script here, e.g.: ./configure make To install them (by default in /usr/local/bin, /usr/local/lib, etc), then do: make install (If the configure script can't determine your type of computer, give it the name as an argument, for instance ``./configure sun4''. You can use the script ``config.sub'' to test whether a name is recognized; if it is, config.sub translates it to a triplet specifying CPU, vendor, and OS.) If you have more than one compiler on your system, it is often best to explicitly set CC in the environment before running configure, and to also set CC when running make. For example (assuming sh/bash/ksh): CC=gcc ./configure make A similar example using csh: setenv CC gcc ./configure make Much of the code and documentation enclosed is copyright by the Free Software Foundation, Inc. See the file COPYING or COPYING.LIB in the various directories, for a description of the GNU General Public License terms under which you can copy the files. REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info on where and how to report problems.
