Description Jan Vesely 2014-09-25 21:54:00 UTC

Please add configuration variables to select llvm backends at build time.
compiling llvm has become really long especially if you build for 2 or more ABIs.

This change would allow to have llvm for arm, without pulling in all the other arches (Hexagon, nvptx, mips, systemz, ...)

Reproducible: Always

Comment 2 zhanglei.april 2016-08-17 02:13:05 UTC

The latest ebuilds for llvm no longer pulls in all archs.

From llvm-3.8.1.ebuild:
    if use multitarget; then
        targets=all
    else
        targets='host;BPF;CppBackend'
        use video_cards_radeon && targets+=';AMDGPU'
    fi

Fixed in 3.9.0, collapsing all requests into the oldest bug I was able to find ;-).
