- Subject: [patch] Handle oversize registers in debug target
Hello,
This patch changes the ``set debug target 1'' code so that it handles
oversize registers. Previously you would get an error which wasn't
exacly helpful :-(
committed,
Andrew

* target.c (debug_print_register): New function. Handle oversize
registers.
(debug_to_fetch_registers): Call.
(debug_to_store_registers): Call.
