Re: Codelet recycling
This is now coded and v2.43 modules are on the dev site for testing. I've performed brief testing on RO3.71 StrongARM (emulated) and RO5.21 on the Pi, leaving Battle Chess playing itself and 2067BC running the demo for several hours. I've not however tested any existing known working games yet. Batt...

Re: Downloads..
I've put them back online after uploading them all again. I'd advise only downloading the "full archive" and not the individual floppy images, as I'm not in a position to try and fix the underlying corruption issue. At least the ZIP will tell you it's corrupt when you try to extract it.

Re: Downloads..
I'm afraid all downloads are offline until further notice. I'm not in a position to try and resolve the ongoing corruption issue for a while unfortunately, I'm going to see if there's something I can do remotely over the weekend, so check back on Mon to see if there's an update. I can only apologise...

Re: Site maintenance
All attachments are lost and downloads offline following the latest corruption episode. It's looking like Linux is the issue, as I've already replaced the hardware.

Re: Codelet recycling
Whilst coding this, I've realised some SWI codelets need to remain allocated once the original instruction has been overwritten. In hindsight, SWI codelets that contain veneers should probably have been using private memory outside of codelet space for the veneer, but that would have made things mes...

Re: Codelet reentrancy
Its looking like (1) is the only workable option. Although (3) will work, there is a slim possibility that an IRQ will occur during an IRQ if they're reenabled by an IRQ handler - Acorn's original advice on IRQ handlers is to switch to SVC and reenable IRQ's as soon as possible if they're going to t...

Re: Codelet recycling
At the moment, memory allocated to codelets is leaked (until the JIT is reset) when the original instruction they implement is overwritten by either self-modifying code or by loading data/code over them. Its not an issue for most games, ones that continually self-modify however run out of codelet sp...

Codelet recycling
Changes required to implement codelet recycling: GOARM3JIT needs to initialize the codelet "firstfree" pointer (coded) GOARM3JIT needs to initialize the first codelet heap entries (coded) CODELET macros need to scan for a free codelet block big enough for the requested codelet size (coded)...
