# Note: flags over sse3 aren't really used -- they're only
# boilerplate. They also make some silly assumptions, e.g. that
# every CPU with SSE4* has SSSE3.
# Reference: https://bugs.funtoo.org/browse/FL-2069.
# If you want to re-add them, first check if the code started
# using them. If it did, figure out if the flags can be unbundled
# from one another. Otherwise, you'd have to do REQUIRED_USE.
