sparc runVMTests
by Valery Ushakov 21 Apr '23

21 Apr '23

runVMTests on sparc (Debug build) fails in a few places. If someone familiar with the internals could point me towards places in the source code to look at to investigate the problems, that would be very helpful. https://paste.sr.ht/~nbuwe/5bdf787b15e8319153370ad1a7f2759010490705 RelWithDbgInfo fails during creation of the world with "must cross stacks" assertion in frame::make_full_frame_on_user_stack() -uwe

Yoshiki Ohshima - Croquet Microverse - 26 April 2023
by Giovanni Corriga 20 Apr '23

20 Apr '23

For this month's online presentation, Yoshiki Ohshima will demonstrate the Croquet Microverse ( https://croquet.io/ ), which is a 3D collaborative construction environment. It is an incarnation of Smalltalk-based Croquet but instead implemented in JavaScript. Microverse allows a group of users to collaboratively create new objects in a virtual space, and describe their behaviors in the live programming manner that can be used by professional programmers. The object extension mechanism used in the Microverse is heavily influenced by past class and object extension mechanisms, many of which originated from experimentation and implementation in Smalltalk. Likewise, the architecture of the Microverse application framework draws upon other frameworks such as Morphic and AppKit. Yoshiki will explain the connections between those systems and the Microverse. Yoshiki ( https://tinlizzie.org/ohshima/ ) joined Walt Disney Imagineering R&D in 2000 as an intern while attending the graduate school of Tokyo Institute of Technology, and helped develop prototypes of Disney's theme park attractions. He also has been involved in Alan Kay's research group, and participated in the research and development effort of education programming environment Squeak Etoys and later took the leading role. Yoshiki has worked at the Viewpoints Research Institute, SAP Labs CDG, and Y Combinator Research, all of which Dr. Kay founded or helped found. He was awarded his PhD. for designing and implementing a massively parallel particle programming system from Tokyo Institute of Technology. This will be an online meeting from home. If you'd like to join us, please sign up in advance on the meeting's Meetup page ( https://www.meetup.com/ukstug/events/292570084/ ) to receive the meeting details.

Self on SPARC
by Valery Ushakov 07 Apr '23

07 Apr '23

The SPARC port required just a few trivial clean up commits and one straightforward change to support NetBSD ucontext_t (different names) to get built on NetBSD/sparc. Haven't tried GUI yet, but the basic world seems to build. https://github.com/nbuwe/self/commits/feature/netbsd-sparc There is just one serious issue - in the intervening years the SPARC ABI reserved %g7 for system use and it's currently used for thread-local storage block pointer. The default malloc implementation on NetBSD always uses TLS, so it relies on that %g7 not being clobbered. The self compiler uses %g7 for the stack limit (SPLimitReg). I'm currently cheating by using a libc with a different, more simple malloc implementation that doesn't use TLS. The compiler needs to be modified to move SPLimitReg to a different register at the cost of losing one temp, I guess. -uwe
