Hi, |

|
| 3 |
As the Perl Team raised the issue of "arm-linux" keywords in the |
| 4 |
ebuilds[1], I think it is a good chance to completely remove them from |
| 5 |
our tree. |
| 6 |
|
| 7 |
What is "arm-linux" keyword? Gentoo Prefix has 2 kinds of profiles. An |
| 8 |
libc profile builds glibc in a Prefix and uses implicit keywords, while |
| 9 |
An rpath profile uses host glibc and uses explicit keywords |
| 10 |
"${ARCH}-linux". Therefore arm-linux represents rpath flavor of arm |
| 11 |
Prefix. |
| 12 |
|
| 13 |
In the profiles/, however, we use "arm-linux" to represent Prefix in |
| 14 |
arch.list and profiles.desc. And that bears no relation with keywords |
| 15 |
in the ebuilds. |
| 16 |
|
| 17 |
|
| 18 |
How did "arm-linux" appear? Around 2013, both the ARM Arch Team and the |
| 19 |
Prefix Team were interested in supporting Prefix on ARM. In the Prefix |
| 20 |
Team, a debate of implicit vs explicit keywording was on-going. At the |
| 21 |
same time, the ARM Arch Team went ahead to plant arm-linux into the |
| 22 |
tree. |
| 23 |
|
| 24 |
What is the status of "arm-linux" keywords? They are unmaintained and |
| 25 |
has not been touched for 5+ years. At present, the Prefix Project is |
| 26 |
phasing out Linux rpath profiles and using libc profiles as default. |
| 27 |
There has been no commit in the gentoo.git history regarding "arm-linux" |
| 28 |
keyword. The gentoo-x86 CVS history shows the commit author was mainly |
| 29 |
Zac (zmedico). |
| 30 |
|
| 31 |
What is recommended? Just use the "arm" keyword, it has been proven to |
| 32 |
work well as an implicit ARM Prefix keyword by the Android Project[2]. |
| 33 |
|
| 34 |
|
| 35 |
"arm-linux" is considered deprecated, unmaintained and easily replaced |
| 36 |
by "arm". I propose removing it from gentoo.git completely. |
| 37 |
