Subject: [PATCH v4 60/78] ncr5380: Implement new eh_abort_handler
Date: Sun, 03 Jan 2016 16:06:01 +1100 [thread overview]
Message-ID: <20160103050516.911765777@telegraphics.com.au> (raw)
In-Reply-To: 20160103050501.042035135@telegraphics.com.au
[-- Attachment #1: ncr5380-new-eh_abort_handler --]
[-- Type: text/plain, Size: 12620 bytes --]
Introduce a new eh_abort_handler implementation. This one attempts to
follow all of the rules relating to EH handlers. There is still a known
bug: during selection, a command becomes invisible to the EH handlers
because it only appears in a pointer on the stack of a different thread.
This bug is addressed in a subsequent patch.
