[RFA][PATCH v4 2/5] S/390: Add TDB regset

Andreas Arnez
2013-07-03T17:02:42Z

The z/Architecture transactional-execution facility includes support
for a "transaction diagnostic block" (TDB) that is written by the
hardware upon interrupted transactions. From a running inferior the
TDB can be retrieved via PTRACE_GETREGSET, but ENODATA is returned if
the inferior was interrupted outside transactions. Analogously, a
core file conditionally contains the TDB, depending on whether the
process died within a transaction or not.

This patch represents the TDB as a new regset in GDB. A new feature
"org.gnu.gdb.s390.tdb" is defined and new target descriptions are
provided.

+S/390 targets should provide the 32-bit versions of these registers.
