Binutils with MCST patches

PR tui/14126 notes that ANSI terminal escape sequences don't affect the colors shown in the TUI. A simple way to see this is to try the extended-prompt example from the gdb manual. Curses does not pass escape sequences through to the terminal. Instead, it replaces non-printable characters with a visible representation, for example "^[" for the ESC character. This patch fixes the problem by adding a simple ANSI terminal sequence parser to gdb. These sequences are decoded and those that are recognized are turned into the appropriate curses calls. The curses approach to color handling is unusual and so there are some oddities in the implementation. Standard curses has no notion of the default colors of the terminal. So, if you set the foreground color, it is not possible to reset it -- you have to pick some other color. ncurses provides an extension to handle this, so this patch updates configure and uses it when available. Second, in curses, colors always come in pairs: you cannot set just the foreground. This patch handles this by tracking actually-used pairs of colors and keeping a table of these for reuse. Third, there are a limited number of such pairs available. In this patch, if you try to use too many color combinations, gdb will just ignore some color changes. Finally, in addition to limiting the number of color pairs, curses also limits the number of colors. This means that, when using extended 8- or 24-bit color sequences, it may be possible to exhaust the curses color table. I am very sour on the curses design now. I do not know how to write a test for this, so I did not. gdb/ChangeLog 2018-12-28 Tom Tromey <tom@tromey.com> PR tui/14126: * tui/tui.c (tui_enable): Call start_color and use_default_colors. * tui/tui-io.c (struct color_pair): New.

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.
