Can you add some kind of define or dynamic processor definnition in your patch so that we can keep track of the exact instruction set ?3. [PATCH] Add special MIPS multiply instructions http://lists.gnu.org/archive/html/qemu-devel/2006-04/msg00375.htmlSame remark.These are NEC VR54xx specific extensions to the MIPS instruction set. They are used if you use GCC's -march=vr5400 option. See www.necelam.com/docs/files/1375_V2.pdf as well.
Yes, I will update the patch. Any ideas or proposals from anybody how to do this the best way? Are there already examples from other architectures?
I think a define to be able to completely select/unselect it at compile time combined with possibility for dynamic runtime selection would be the best?
