I have seen an application note "How to write better C code for ARM" -
It would tell how to get better output using ARM compiler.
IMO, the compiler writer has to understand the Instruction set power
and consider what kind of application the compiler would be used, to
decide on the optimization.
Also there cant be a single document on how to optimize for a specific
instruction set. Optimizations specific to a processor instruction set
also evolves on feedback from the application developers/testers..
