Tom Tromey 6999161a2a 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 a8a5dbcab8. 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. gdb/ChangeLog 2019-10-23 Tom Tromey <tom@tromey.com> * Makefile.in (READLINE_DIR): Update. gdb/doc/ChangeLog 2019-10-23 Tom Tromey <tom@tromey.com> * Makefile.in (READLINE_DIR): Update. readline/ChangeLog 2019-10-23 Tom Tromey <tom@tromey.com> Move old contents to readline/ subdirectory. * aclocal.m4, configure, configure.ac, .gitignore, Makefile.am, Makefile.in, README: New files.
