- 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")
