Modified path to qemu package source to /sf/adapt/qemu
This is to conform with the convention that adaptation-level packages
should be located in /sf/adapt rather than /sf/adaptation.
This is an interim workaround for bug 3744.
- Add new instructions such as: andnot, ror, rol, 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.
