There seems to be a lot of problems that either are, or might be associated with
people using binaries on older CPUs than what they are made on. (e.g see the
thread "A command which causes Sage to crash" on sage-support).
It would be useful if there was a script or something which detected the
incompatibility early, and warned someone immediately.
On Solaris, I can do the following to see what instructions the CPU supports.
drkir...@hawk:~$ isainfo -v
64-bit amd64 applications
sse4.2 sse4.1 ssse3 popcnt tscp cx16 mon sse3 pause sse2 sse fxsr mmx
cmov amd_sysc cx8 tsc fpu
32-bit i386 applications
sse4.2 sse4.1 ssse3 popcnt tscp ahf cx16 mon sse3 pause sse2 sse fxsr
mmx cmov sep cx8 tsc fpu
I believe there is also a command which can list what instructions an executable
needs, though I can't be sure.
