Re: ARM ABI changes/combinations (was Re: Preparation for creating netbsd-7 branch)
On 7/22/14, 2:28 PM, Jeff Rizzo wrote:
So, what I am proposing:
- acorn26, acorn32, epoc32 remain MACHINE_ARCH=arm
- cats, netwinder, shark switch to MACHINE_ARCH=earmv4 (rename oabi
equiv to ocats, onetwinder, oshark)
- hpcarm, iyonix, zaurus switch to MACHINE_ARCH=earm (which is
equivalent to earmv5, correct?)
- evbarm switch default MACHINE_ARCH=earm, and also build the
following MACHINE_ARCHes:
* earm, earmeb
* earmhf, earmhfeb
* earmv6hf
* earmv7hf
Does this make sense? If so, i'll post a diff with the proposed
change to src, and once that's committed, I'll fix up the autobuild.
Does anyone have a start at documenting this on the wiki for someone
who might actually want to use one of our arm ports? :)

Attached is the proposed diff to build.sh with the changes, including
hpcarm -> MACHINE_ARCH=earmv4 .
I would like to commit this in the next 48h unless there are objections.
