Re: Code selection trade-offs

Hi Tim,

Do you know of any works where profiling information/ static program
analysis is used as a heuristic to control code selection, i.e. the
(profiling) execution counts of particular code structures are
influencing the choice of instructions used to translate the source
code into assembler?


This may be a little off-topic, but in this paper a technique is used
that uses profiling based basic block execution counts to guide the
generation of new instructions for extensible processor cores that
allow you to define your own application-specific instruction set
extensions:

Cheers,
