I haven't tried 32bit yet but I will soon.<br> - I was thinking more about this WOW64 GetThreadContext problem and ways to mitigate it, other than cooperative suspend.<br> I had already suggested and started to implement scanning the entire stack -- i.e. not depending on an ability to get ESP from a suspended thread.<br> Like how FreeBSD and OpenBSD work, albeit it is a significant deoptimization.<br> Regarding the rest of the context, perhaps it is a reasonable assumption for now to declare that it doesn't matter? e.g. to know/assume<br> that m3back never leaves a value only in registers, that anything in a register will also be on the stack? And to disable optimization on the<br> hypothetical MINGW platforms. ?<br> But still to confirm if there are no problems on 32bit, and to mull over implementing cooperative suspend..in the little time available...<br> (Oh, and also, I wonder if SuspendThread can suspend a thread while in the kernel, probably, and if GetThreadContext returns<br> the kernel context in that case; should be easy to determine via some experimentation -- which would imply a problem on 32bit Windows also.)<br> <br> <br> - Jay<br> <br><hr id="stopSpelling">From:<span class="Apple-converted-space"> </span><a href="mailto:hosking@cs.purdue.edu">hosking@cs.purdue.edu</a><br>Date: Mon, 14 Mar 2011 17:21:01 -0400<br>To:<span class="Apple-converted-space"> </span><a href="mailto:rcolebur@SCIRES.COM">rcolebur@SCIRES.COM</a><br>CC:<span class="Apple-converted-space"> </span><a href="mailto:m3devel@elegosoft.com">m3devel@elegosoft.com</a><br>Subject: Re: [M3devel] question re LONGINT<br><br>This is a known problem which I am still to fix.
