Move readline to the readline/readline subdirectory
readline turns out to be a bit of a stumbling block for the project to
move gdbsupport (and then gdbserver) to the top-level.
The issue is that readline headers are intended to be included with
names like "readline/readline.h". To support this, gdb effectively
adds a -I option pointing to the top-level source directory -- but,
importantly, this option is not used when the system readline is used.
For gdbsupport, a -I option like this would always be needed, but that
in turn would break the system readline case. This was PR build/17077,
fixed in commit a8a5dbcab8df0b3a9e04745d4fe8d64740acb323.
Previously, we had discussed this on the gdb-patches list in terms of
removing readline from the tree
https://sourceware.org/ml/gdb-patches/2019-09/msg00317.html
However, Eli expressed some concerns, and Joel did as well (off-list).
Given those concerns, and the fact that a patch-free local readline is
relatively new in gdb (it was locally patched for years), I changed my
mind and decided to handle this situation by moving the readline
sources down a level.
That is, upstream readline is now in readline/readline, and the
top-level readline directory just contains the minimal configury
needed to build that.
This fixes the problem because, when gdb unconditionally adds a
-I$(top_srcdir), this will not find readline headers. A separate -I
will be needed instead, which is exactly what's needed for
--with-system-readline.

-Introduction
-============
+This is an import of readline that is used by gdb.
-This is the Gnu Readline library, version 8.0.
+To send patches, follow the gdb patch submission instructions in
+../gdb/CONTRIBUTE. For maintainers, see ../gdb/MAINTAINERS.
-The Readline library provides a set of functions for use by applications
-that allow users to edit command lines as they are typed in. Both
-Emacs and vi editing modes are available. The Readline library includes
-additional functions to maintain a list of previously-entered command
-lines, to recall and perhaps reedit those lines, and perform csh-like
-history expansion on previous commands.
+If you need to patch readline, please document the changes here.
-The history facilites are also placed into a separate library, the
-History library, as part of the build process. The History library
-may be used without Readline in applications which desire its
-capabilities.
+To import, copy the upstream readline sources into the "readline"
+subdirectory, remembering to (1) remove any files that were deleted
+upstream, and (2) merge the one small configure.ac patch that gdb
+carries.
-The Readline library is free software, distributed under the terms of
-the [GNU] General Public License as published by the Free Software
-Foundation, version 3 of the License. For more information, see the
-file COPYING.
-
-To build the library, try typing `./configure', then `make'. The
-configuration process is automated, so no further intervention should
-be necessary. Readline builds with `gcc' by default if it is
-available. If you want to use `cc' instead, type
-
- CC=cc ./configure
-
-if you are using a Bourne-style shell. If you are not, the following
-may work:
-
- env CC=cc ./configure
-
-Read the file INSTALL in this directory for more information about how
-to customize and control the build process.
-
-The file rlconf.h contains C preprocessor defines that enable and disable
-certain Readline features.
-
-The special make target `everything' will build the static and shared
-libraries (if the target platform supports them) and the examples.
-
-Examples
-========
-
-There are several example programs that use Readline features in the
-examples directory. The `rl' program is of particular interest. It
-is a command-line interface to Readline, suitable for use in shell
-scripts in place of `read'.
-
-Shared Libraries
-================
-
-There is skeletal support for building shared versions of the
-Readline and History libraries. The configure script creates
-a Makefile in the `shlib' subdirectory, and typing `make shared'
-will cause shared versions of the Readline and History libraries
-to be built on supported platforms.
-
-If `configure' is given the `--enable-shared' option, it will attempt
-to build the shared libraries by default on supported platforms.
-
-Configure calls the script support/shobj-conf to test whether or
-not shared library creation is supported and to generate the values
-of variables that are substituted into shlib/Makefile. If you
-try to build shared libraries on an unsupported platform, `make'
-will display a message asking you to update support/shobj-conf for
-your platform.
-
-If you need to update support/shobj-conf, you will need to create
-a `stanza' for your operating system and compiler. The script uses
-the value of host_os and ${CC} as determined by configure. For
-instance, FreeBSD 4.2 with any version of gcc is identified as
-`freebsd4.2-gcc*'.
-
-In the stanza for your operating system-compiler pair, you will need to
-define several variables. They are:
-
-SHOBJ_CC The C compiler used to compile source files into shareable
- object files. This is normally set to the value of ${CC}
- by configure, and should not need to be changed.
-
-SHOBJ_CFLAGS Flags to pass to the C compiler ($SHOBJ_CC) to create
- position-independent code. If you are using gcc, this
- should probably be set to `-fpic'.
-
-SHOBJ_LD The link editor to be used to create the shared library from
- the object files created by $SHOBJ_CC. If you are using
- gcc, a value of `gcc' will probably work.
-
-SHOBJ_LDFLAGS Flags to pass to SHOBJ_LD to enable shared object creation.
- If you are using gcc, `-shared' may be all that is necessary.
- These should be the flags needed for generic shared object
- creation.
-
-SHLIB_XLDFLAGS Additional flags to pass to SHOBJ_LD for shared library
- creation. Many systems use the -R option to the link
- editor to embed a path within the library for run-time
- library searches. A reasonable value for such systems would
- be `-R$(libdir)'.
-
-SHLIB_LIBS Any additional libraries that shared libraries should be
- linked against when they are created.
-
-SHLIB_LIBPREF The prefix to use when generating the filename of the shared
- library. The default is `lib'; Cygwin uses `cyg'.
-
-SHLIB_LIBSUFF The suffix to add to `libreadline' and `libhistory' when
- generating the filename of the shared library. Many systems
- use `so'; HP-UX uses `sl'.
-
-SHLIB_LIBVERSION The string to append to the filename to indicate the version
- of the shared library. It should begin with $(SHLIB_LIBSUFF),
- and possibly include version information that allows the
- run-time loader to load the version of the shared library
- appropriate for a particular program. Systems using shared
- libraries similar to SunOS 4.x use major and minor library
- version numbers; for those systems a value of
- `$(SHLIB_LIBSUFF).$(SHLIB_MAJOR)$(SHLIB_MINOR)' is appropriate.
- Systems based on System V Release 4 don't use minor version
- numbers; use `$(SHLIB_LIBSUFF).$(SHLIB_MAJOR)' on those systems.
- Other Unix versions use different schemes.
-
-SHLIB_DLLVERSION The version number for shared libraries that determines API
- compatibility between readline versions and the underlying
- system. Used only on Cygwin. Defaults to $SHLIB_MAJOR, but
- can be overridden at configuration time by defining DLLVERSION
- in the environment.
-
-SHLIB_DOT The character used to separate the name of the shared library
- from the suffix and version information. The default is `.';
- systems like Cygwin which don't separate version information
- from the library name should set this to the empty string.
-
-SHLIB_STATUS Set this to `supported' when you have defined the other
- necessary variables. Make uses this to determine whether
- or not shared library creation should be attempted.
-
-You should look at the existing stanzas in support/shobj-conf for ideas.
-
-Once you have updated support/shobj-conf, re-run configure and type
-`make shared'. The shared libraries will be created in the shlib
-subdirectory.
-
-If shared libraries are created, `make install' will install them.
-You may install only the shared libraries by running `make
-install-shared' from the top-level build directory. Running `make
-install' in the shlib subdirectory will also work. If you don't want
-to install any created shared libraries, run `make install-static'.
-
-Documentation
-=============
-
-The documentation for the Readline and History libraries appears in
-the `doc' subdirectory. There are three texinfo files and a
-Unix-style manual page describing the facilities available in the
-Readline library. The texinfo files include both user and
-programmer's manuals. HTML versions of the manuals appear in the
-`doc' subdirectory as well.
-
-Usage
-=====
-
-Our position on the use of Readline through a shared-library linking
-mechanism is that there is no legal difference between shared-library
-linking and static linking--either kind of linking combines various
-modules into a single larger work. The conditions for using Readline
-in a larger work are stated in section 3 of the GNU GPL.
-
-Reporting Bugs
-==============
-
-Bug reports for Readline should be sent to:
-
- bug-readline@gnu.org
-
-When reporting a bug, please include the following information:
-
- * the version number and release status of Readline (e.g., 4.2-release)
- * the machine and OS that it is running on
- * a list of the compilation flags or the contents of `config.h', if
- appropriate
- * a description of the bug
- * a recipe for recreating the bug reliably
- * a fix for the bug if you have one!
-
-If you would like to contact the Readline maintainer directly, send mail
-to bash-maintainers@gnu.org.
-
-Since Readline is developed along with bash, the bug-bash@gnu.org mailing
-list (mirrored to the Usenet newsgroup gnu.bash.bug) often contains
-Readline bug reports and fixes.
