Subject: [PATCH v3 27/29] Introduce win32_target_ops::decr_pc_after_break
Date: Fri, 13 Mar 2020 13:08:53 -0600 [thread overview]
Message-ID: <20200313190855.28662-28-tromey@adacore.com> (raw)
In-Reply-To: <20200313190855.28662-1-tromey@adacore.com>
This adds a decr_pc_after_break member to win32_target_ops and updates
the two Windows targets to set it.
Note that I can't test the win32-arm-low.c change.
gdbserver/ChangeLog
2020-03-13 Tom Tromey <tromey@adacore.com>
* win32-low.h (struct win32_target_ops) <decr_pc_after_break>: New
field.
* win32-i386-low.c (the_low_target): Update.
* win32-arm-low.c (the_low_target): Update.
