DWARF symbols on disk to speed up further loading of the same
binaries.
+ Various GDB/MI enhancements.
+ GDBserver on PowerPC GNU/Linux now supports access to the PPR,
DSCR, TAR, EBB/PMU, and HTM registers.
+ Ada task switching support when debugging programs built with
the Ravenscar profile added to aarch64-elf.
