Hi All,
Our project is - to optimize instruction scheduling in gcc, by
detecting structural hazards. We are looking at the dfa(deterministic finite
automaton) currently used by gcc to detect structural hazards. We have the
following doubts regarding the same:
1. The starting point of generation of dfa(by reading md files) is
'genautomata.c'. When is the main() method of 'genautomata.c' called?
2. How and in what datastructure - is the dfa generated by 'genautomata.c'
persisted between two method calls - one of main() method of genautomata.c
and another of toplev_main() method of toplev.c
Kindly help us with our issues.
Thanking You,
Dhiraj.
