- Subject: [commit] Adding support for Xtensa GNU/Linux
This patch adds support for Xtensa GNU/Linux.
We like XML approach to describe register files. It matches
Xtensa, which requires register files to be easily configurable.
But, we need more time to update Xtensa FSF GDB/GDBSERVER
to start fully using this feature. So this version of Xtensa
FSF GDB/GDBSERVER does not use this new approach.
