Pharo VM Release - v9.0.21
Hello, I have released a new version of the Pharo VM for Pharo 9, Pharo 10 and Pharo 11. This VM is accessible right now from Zero-Conf, updating it in the Pharo Launcher or using the usual downloads (as described in pharo.org/download). This version includes a series of bug fixes and upgrades on the third-party libraries. Changelog: - Implementing High resolution clock for ARM64 (Used during profiling) - Updating third party libraries for all the graphic layer. - Fixing a performance regression on the allocation of opcodes and fix-ups. Cleaning only the ones that are going to be used. Like this, this version has the same speed than before when allocating in the stack. - Correctly handling the encoding of the command line arguments of the VM (Windows) - Allocating the opcodes and fixup structs only once and reusing them (Reducing risk of C Stack Overflow) Thanks a lot, and any doubt please let me know. Cheers, Pablo on behalf of the whole Pharo team. -- Pablo Tesone. tesonep@gmail.com

Hi Pablo, I'm on Pharo 10 and intermittently experience "the spinning wheel" when making LibC calls. The spin dump is below. I'm wondering if the last fix: - Allocating the opcodes and fixup structs only once and reusing them (Reducing risk of C Stack Overflow)) would potentially rectify this? Thanks to you and the whole team for all the great work on the machine! Stewart Thread 0x9a54d 1000 samples (1-1000) priority 46 (base 46) 1000 ??? [0x1062e1a78] 1000 ??? [0x1063c2374] 1000 ???
