Description Stefan Sydow 2016-11-23 15:23:10 UTC

Created attachment 454128 [details, diff]
patch for llvm 3.9.0 to work on arm64

for abi="arm64" the line:
local abi_chost=$(get_abi_CHOST "${abi}")

will return an empty CHOST which is used and not checked to create symlinks in /usr/bin/.

Here is a patch attached to guard against that, because the symlinks are not so important if one does not cross compile for that architecture.

A better way would be to repair get_abi_CHOST on arm64.

The arch profile should be ensuring that CHOSTs are set correctly. I'm not really interested in working that around in random applications.

    profiles/default/linux/arm64: Fix parent to little-endian, #600590
    
    Fix the parent profile of default/linux/arm64 from top-level arch/arm64
    to little-endian subprofile. This is what the profile structure
    suggests, and (unlike the top profile) it defines CHOST
    (and CHOST_arm64) as required by package manager, eclasses and ebuilds.
