All exiting techniques devoted for basic blocks work also for
superblock. A Superblock is considered as a basic block when doing
instruction scheduling and register allocation: this is why
superblocks have been introduced in compilers. Meanwhile, a post pass
introduces a recovery code to correct code semantics.


So, you do not need a specific code optimisation for a superblock, you
can take any technique for a basic block and it would work for a
superblock. However, this assertion may not be correct for other code
regions ans shapes (hyperblock, trees, etc.)
