# avoid breakage in newer CPU ISAs, supporting SSE2 should be enough for
# 32-bit platforms
# for special use cases (like running Archlinux32 on 64-bit hardware)
# we can support up to SSE4.2 (everything above is too hard to fix).
# As Embree chooses the ISA at runtime, this is no problem for machines
# not having SSE4.2
