It seems the old one was just broken (see mailing list discussion.) This new one was built from the generic one, but it was done using a trunk build of Clang 8 with tuned optimization flags, and is smaller (101 instructions) than GCC 8's (134 instructions) and the old hand-optimized one (~125 instructions?) as well as being targeted for ARMv7 instead of ARMv6 like the old one was. In the future, we may want to look at newlib's ARM memcpy, which is probably much more hand-optmized than this one is, but this is at least better than what we had before.
Haiku
Homepage | Mailing Lists | IRC Channels | Issue Tracker | API docs
Haiku is an open-source operating system that specifically targets personal computing. Inspired by the BeOS, Haiku is fast, simple to use, easy to learn and yet very powerful.
Goals
- Sensible defaults with minimal configuration required.
- Clean, clear, concise code.
- Unified desktop environment.
Trying Haiku
Haiku provides pre-built nightly images and release images. Haiku is compatible with a large variety of hardware, but in case you don't want to "take the plunge" and install Haiku on bare metal, you can install it on a virtual machine (VM) instead. If you've never used a VM before, you can follow one of the "Emulating Haiku" guides.
Compiling Haiku
See ReadMe.Compiling.
Contributing
Haiku is a meritocratic open source project with a large variety of tasks. Even if you can't write code, you can still help! Haiku needs designers, (technical) writers, translators, testers... Get involved and help out!
