- Add new instructions such as: setcond, clz, ctz, popcnt. - See if it is worth exporting mul2, mulu2, div2, divu2. - Support of globals saved in fixed registers between TBs. Ideas: - Move the slow part of the qemu_ld/st ops after the end of the TB. - Change exception syntax to get closer to QOP system (exception parameters given with a specific instruction). - Add float and vector support.
