# parabola changes and rationale:
# - Added armv7h and i686 architectures
# - Added workaround for -fvar-tracking-assignments being in the
#   default /etc/makepkg.conf
# - Added depends=('lld' 'llvm') to be able to build llvm-lto

# The Arch Linux wiki page on clang[1] has the following:
# "If you are building with debug, also remove
# -fvar-tracking-assignments from DEBUG_CFLAGS and DEBUG_CXXFLAGS as
# Clang does not support it."
# [1]https://wiki.archlinux.org/title/Clang
# And -fvar-tracking-assignments is by default in /etc/makepkg.conf
#
# And without that fix we have the following compilation error:
#     clang-13: error: unknown argument: '-fvar-tracking-assignments'
#     [...]
#     [-] Compiling afl-cc failed. You seem not to have a working compiler.
#     [...]
#     ==> ERROR: A failure occurred in build().
