Optimisation and ArmV8 64 bit systems
by Bruce O'Neel 21 Oct '19

21 Oct '19

Hi, On my tiny Arm V8 system (Nvidia Jetson Nano, Arm A57, [https://www.nvidia.com/en-us/autonomous-machines/embedded-systems/jetson-na…) running Nvidia's distribution of Ubuntu 18.04 the optimised build for a VM that doesn't do floating point. For example 1.0 / 3.0 is 0.0. Gcc version 7.4.0. The debug build, and the assert build both work fine. If I reduce the optimisation from -O2 to -O1 it's ok. I'm building the VM in opensmalltalk-vm/build.linux64ARMv8/squeak.stack.spur. This is more to stop someone from as much head scratching for them as it is for me... Thanks. bruce

[OpenSmalltalk/opensmalltalk-vm] Some BitBlt operations read past source end (#426)
by Nicolas Cellier 20 Oct '19

20 Oct '19

While running an assert or debug VM, I noticed repeated logs in console: > (((usqInt)sourceIndex)) < endOfSource 2132 This corresponds to failing assert: in BitBltSimulation slang srcLongAt: idx <inline: #always> self assert: idx asUnsignedInteger < endOfSource. ^self long32At: idx It is easily reproducible with this Squeak test: BitmapStreamTests new testShortIntegerArrayReadRefStream2. Such read past end is benign, except in rare case when we read past a page boundary and cause a SEGV! Via LLDB or via VM SImulation, we can find that it is related to the case when we `preload `a word from source and next source word because we think that we need more than 1 source word to fill 1st dest word. I have identified and hopefully fixed the bug in VMMaker.oscog-nice.2563 https://source.squeak.org/VMMaker/VMMaker.oscog-nice.2563.diff -- You are receiving this because you are subscribed to this thread.

VM Maker: VMMaker-dtl.403.mcz

David T. Lewis uploaded a new version of VMMaker to project VM Maker: http://source.squeak.org/VMMaker/VMMaker-dtl.403.mcz ==================== Summary ==================== Name: VMMaker-dtl.403 Author: dtl Time: 18 October 2019, 8:15:50.289 pm UUID: dd763318-ebf1-426e-ba9b-f7a45e611ebb Ancestors: VMMaker-dtl.402 Add missing methods so that SlangBrowser works again on classes and methods that are not part of the VM. Methods that can be translated to C (or inlined C) are displayed, others result in assertion errors or invalid C code. For example, Scanner>>scanFieldNames: and many other methods in class Scanner are translated to C or inlined C, but Scanner>>scanAllTokenPositionsInto: cannot be translated and fails with an assertion error. =============== Diff against VMMaker-dtl.402 =============== Item was added: + ----- Method: TMethod>>comment (in category 'accessing') ----- + comment + ^comment!

Hi everyone, Is there some place I can find a document describing what subset of Smalltalk is supported in Slang in its current state? Thank you. Laurent
