<html><head></head><body> <div>10 Years back Dan provided a system tracer to convert Squeak images from 32 bit PowerPC to 64 bit intel. I recall spending a few days resolving an issue where the floating point endian wasn’t correct for some FP situations. So check the archives for a post from him with regard to 64 bit. I also built a number of vm variations, perhaps an image from there is useful? <a href="ftp://smalltalkconsulting.com/experimental/64bit/">ftp://smalltalkconsulting.com/experimental/64bit/</a></div><div><br></div><div><caret></caret><br></div><div></div><div><br></div><div id="protonmail_mobile_signature_block"><div>Sent from ProtonMail for iOS</div></div> <div><br></div><div><br></div>On Fri, Apr 23, 2021 at 22:50, stes@PANDORA.BE <<a href="mailto:stes@telenet.be" class="">stes@telenet.be</a>> wrote:<blockquote class="protonmail_quote" type="cite"> <br>Hi Marcel,<br><br>The reference in http://wiki.squeak.org/squeak/2315 (last paragraph),<br>I read the info in the "The Interactive Programming Environment" red book,<br>by Adele Goldberg: it says in 23.4 page 487<br><br>"To initiate the VMem-write, evaluate the expression<br><br> SystemTracer writeClone"<br><br>Anyway I have not yet been succesful in running converted 64bit images,<br>but if you have done it, I'd be interested in this.<br><br>Also the above SystemTracer writeClone which according to the red book,<br>worked in old Smalltalk systems, does not work for me nowadays.<br><br>I get the error: SmalltalkImage allBehaviorsDo: message not understood.<br>in Squeak4.6.<br><br>In Squeak6.0 with the Cog VM I get a subscript out of bounds in clamp:<br><br>I think writeClone and clamp: are messages from the SystemTracer package.<br><br>David Stes<br></blockquote><div><br></div><div><br></div></body></html>
