[PATCH 0/7] amdgpu: handle fork and exec

[Simon Marchi <simon.marchi@efficios.com>]

This series adds support for fork and exec to the amdgpu port.  This
means making sure that the appropriate cleanups are done when an
inferior using the GPU forks and / or execs, and the appropriates
actions taken so that we can properly debug an inferior using the GPU
post-fork or post-exec.

Simon Marchi (7):
  gdb: pass execing and following inferior to inferior_execd observers
  gdb: add inferior_forked observable
  gdb: remove regcache::target
  gdb: add maybe_switch_inferior function
  gdb: make regcache::raw_update switch to right inferior
  gdb: switch to right inferior in fetch_inferior_event
  gdb/amdgpu: add follow fork and exec support
