ARM ABI has different alignment requirements based on parameter size: * parameters not larger than 4 bytes are aligned on 4 bytes * parameters larger than 4 bytes are aligned on 8 bytes see: Procedure Call Standard for the Arm Architecture sections 5.1, Fundamental Data Types and 6.5, Parameter Passing Therefore the following changes are introduced in gensyscalls tool: * new optional define SYSCALL_LONG_PARAMETER_ALIGNMENT_TYPE is introduced * it's defined only on ARM * on other architectures it takes on the value of SYSCALL_PARAMETER_ALIGNMENT_TYPE as a default * constants kLongParameterAlignmentType and kLongParameterAlignmentSize are introduced * Syscall::AddParameter uses this value for aligning parameters larger than 4 bytes Change-Id: I7e766e0ea9d07001643e813722b462b1f044921a Reviewed-on: https://review.haiku-os.org/c/haiku/+/5112 Reviewed-by: Adrien Destugues <pulkomandy@gmail.com> Tested-by: Commit checker robot <no-reply+buildbot@haiku-os.org>
Haiku

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!
