windows-nat: Replace __COPY_CONTEXT_SIZE conditional with __CYGWIN__

Replace __COPY_CONTEXT_SIZE conditional with __CYGWIN__

__COPY_CONTEXT_SIZE was added to Cygwin's headers in 2006.

Versions of Cygwin which don't define __COPY_CONTEXT_SIZE are long obsolete.

Also see the thread starting at
https://sourceware.org/ml/gdb-patches/2015-03/msg00989.html for some discussion

Note that __COPY_CONTEXT_SIZE should just be sizeof(CONTEXT) (which is a
platform constant), but isn't due to historical mistakes in Cygwin headers.

out_debug_aranges uses frag_align to make sure the addresses start

end up calling TC_FRAG_INIT. On arm and aarch64 TC_FRAG_INIT will

9 years agogdb: Rework command completion on 'tui reg'.
Andrew Burgess [Tue, 26 May 2015 22:23:23 +0000 (23:23 +0100)] 
gdb: Rework command completion on 'tui reg'.

We previously specified a few known register groups for the 'tui reg'
command.  Other register groups could be accessed, but only by using the
'tui reg next' command and cycling through all the groups.

This commit removes the hard coded sub-commands of 'tui reg' and instead
adds dynamic completion of sub-commands based on the architecturally
defined register groups, giving immediate access to all available
register groups.

There is still the 'next' and 'prev' commands for cycling through the
register groups if that's wanted.

The new code maintains the ability to only enter partial names for
register groups, which is something we got for free when using the
standard sub-command mechanism.

The register (and register group) completer has been changed to use
get_current_arch rather than using the architecture of the currently
selected frame.  When the target is running, this is equivalent,
however, when the target is not running, using get_current_arch will
provide results from the default architecture.
