# yuzu requires CX16 instructions (CMPXCHG16B) to build, and they are
|
|
# "only" available on Intel Core 2 or newer CPUs. The only way I know to
|
|
# express that a Debian package depends on a set of instructions not
|
|
# present in the baseline is to make it depend on an isa-support package.
|
|
# Only sse3- and sse4.2-support are available, and there are some CPUs that
|
|
# support SSE3 while not supporting CX16, so depending on that wouldn't be
|
|
# strict enough. The only safe dependency is then sse4.2-support.
|
|
# But depending on sse4.2-support while not making use of the SSE4.2
|
|
# extensions would be a waste, and it makes sense to allow GCC to generate
|
|
# optimized code that uses SSE4.2 extensions, for performance reasons.
|
|
# As both CMPXCHG16B and SSE4_2 are part of the x86-64-v2
|
|
# micro-architecture level, I can simply tell GCC to generate code for that
|
|
# target.
|
|
# Upstream is considering building with SSE4.2 anyway.
