Apparently, some other mechanism is needed, so that vector instructions are only used when they are actually supported by CPU, compiler and assembler.
Your toolchain is broken. You're mixing tools that are 18 years apart, and that never were designed to work together to start with.
I just verified that libsodium still compiles fine on an i386 Mac using Xcode (11.4.1 appears to be the last version that runs).
If you want to use a recent gcc or clang version, I guess you must also use matching versions of related tools such as as, ld, nm, strip, etc.
@jedisct1 Toolchain is fine. The issue is that nothing checks whether instruction set is supported, but just assumes it is. It is certainly possible to implement a check, and it is just a right thing to do: it will improve the code.
P. S. Also CoreDuo itself does not support AVX, whatever tools one might install.
Your gcc frontend generates code for an assembler that doesn't understand it. Your toolchain is broken.
@jedisct1 How is gcc supposed to know what as supports? (Well, if it should check but does not, then it is a bug in gcc.)
I guess it doesn't, and assumes that you are using GNU as, and a version that roughly matches what's commonly available when a gcc version is released. Same thing for the linker, the strip tool, etc.
You can install the GNU binutils package, and then make sure that it's before Apple tools in your PATH. I don't know if they still support macOS/i386, though.
Really, using Xcode is the best way to have a consistent environment. I doubt a lot of people use gcc on macOS. And by the way, libsodium has better performance when using clang.
Well, Xcode 4.2 is the last supported on 10.6, and it is unusable with modern software.
The toolchain I have however is perfectly usable, on my PowerPC system I use exactly the same versions to build everything. If my toolchain was broken, I could not build gcc and CMake to begin with :)
I still think it is configure checks here which fail to work as supposed.
Compare against libopus for example:

It does detect lack of support for AVX (with same gcc) and builds with no errors in result. And most of ports build fine. So far I have encountered 3 related failures with just two looking identical (here and aom).
It could be explained by a lack of testing on affected platforms, which is understandable. But now we have tested it and found that it does not work. Maybe still worth fixing?
Maybe still worth fixing?
No.
Maybe still worth fixing?
No.
Amazing attitude. Well, whatever.
