​If I read Intels data right the core 2 duo didn't support SSE
instructions, but LLVM certainly uses that if it can to expand its register
set (even if it doesn't do streaming).  ​And it could be in Glib or GTK
which would use math more heavily than Geany would.

Jiří is there an option for generating plain vanilla 686 ​code?
