It is "possible" as the MIPS cord (and cord2) tool did it circa
1986-1987. The tool was targeted mostly at direct mapped caches
thoguh so it may not be relevant to what you are doing. (It was also
designed for single level caches and had to know the cache size being
optimized for.) The more modern MIPS/SGI compilers may have a similar
pass that can be turned on at high optimization levels. The original
cord tool was probably written by Mark Himmelstein or Earl Killian but
I don't know. With that info you could try a literature search.
