# These packages are meant to be used for compiling packages that haven't been
# ported to LLVM 3.6 yet. Such packages may depend on llvm35-libs but not on
# llvm35 or clang35 which aren't co-installable with the LLVM 3.6 packages.

# AG Fri Apr 6 07:18:08 CEST 2018: Resurrected from extra from which it
# recently got kicked, with the following changes:

# - couldn't get compiler-rt to compile any more, disabled for now

# - include the host target only, to speed up compilation; if you need the
#   cross compilation targets, change the configure option in the build
#   function to --enable-targets=all

# Please note that this is a split package, thus you need to install this with
# an AUR helper such as aurman which supports that kind of thing, or download
# the PKGBUILD and install manually using makepkg.
