- From the discussion on this that we had ~2 weeks ago, it seems that |
23 |
'multilib_is_native_abi' is only used in the wild now (and only meant |
24 |
to be used) to handle the cases where we want to say, build everything |
25 |
for default_abi and only build certain bits for the others. |
26 |
|
27 |
If there was a common usage that is important for the actual native |
28 |
abi (for instance, some sort of check enabling alternate code in a |
29 |
build system for a specific CHOST or whatnot), then keeping |
30 |
multilib_is_native_abi as it is would make a lot of sense, but since |
31 |
there isn't any cases of this I'm not sure it matters -- changing it's |
32 |
functionality to essentially become multilib_is_default_abi() (whether |
33 |
we rename it or not) seems to make the most sense to me. |

Some users want to have a toolchain that is 64bit and the rest of the |
59 |
userspace that is 32bit. Or, they want to just have certain packages |
60 |
installed 32bits, to support specific use-cases. Essentially, the |
61 |
want to have multi-abi instead of multi-lib, and so they want the |
62 |
current multi-lib to be expanded to allow them to do it. |
