* reverse debugging on aarch64
* new commands or subcommands:
- info os cpu, set/show serial parity, info dll
- maint print symbol-cache/symbol-cache-statistics,
maint flush-symbol-cache
- record btrace bts, record bts
- compile print
- show/set mpx bound
- tui enable/disable
- record btrace pt, record pt
- maint info btrace,
maint btrace packet-history/clear-packet-history/clear
* s390 support for vector ABI
* "set sysroot" improvements related to remote targets
* better support for debugging containerized programs
(without "set sysroot")
* HISTSIZE environment variable is replaced by GDBHISTSIZE
* python scripting:
- it's possible to write frame unwinders
- several new methods in Objfile, Type and Value classes
- gdb can auto-load scripts contained in special sections
named '.debug_gdb_scripts'.
* extensions for the MI interface, new remote packet types
- Removed obsolete patches:
0001-S390-Add-target-descriptions-for-vector-register-set.patch
0001-S390-Fix-compiler-invocation-with-compile-command.patch
0001-S390-Support-new-vector-register-sections.patch

We may abort the process of detaching threads with multiple SIGINTs - which are
|
|
being sent during a testcase terminating its child GDB.
|
|
|
|
Some of the threads may not be properly PTRACE_DETACHed which hurts if they
|
|
should have been detached with SIGSTOP (as they are accidentally left running
|
|
on the debugger termination).
