In GDB 10.x gdbserver was promoted to the top-level folder, see https://sourceware.org/git/?p=binutils-gdb.git;a=commit;h=919adfe8409211c726c1d05b47ca59890ee648f1 Which means it is no longer a subfolder in "gdb" and so we have to build gdbserver now exactly in the same way as normal native GDB. One interesting detail is gdbserver doesn't need to deal with target description in .xml so it doesn't depend on libexpat on target, thus we need to move libexpat explicit selection from do_gdb_backend() to its callers when building native [full] gdb as well as cross-gdb for the host.

Subject: [PATCH 2/2] xtensa: make sure ar_base is initialized
|
|
|
|
ar_base is uninitialized for cores w/o windowed registers as their
|
|
regmap doesn't have register 0x0100.
|
|
Check that ar_base is initialized and if not initialize it with a0_base.
|

|
* xtensa-tdep.c (xtensa_derive_tdep): Make sure ar_base is
|
|
initialized.
