Dear Andreas,

Is it possible to specify a generic architecture to GCC when you compile
the code so that all 3 computational kernels  (non-SSE, SSE3, AVX) get
compiled? Then during runtime IQ-TREE will automatically detect which
kernel it should use, depending on the architecture. I assume that the
non-SSE kernel should run fine on most x86 architecture. If this approach
does not work, then we will provide a flag to exclude the compilation of
the SSE3 and AVX kernels.

Cheers
Tung
