Re: Precedence & Associativity

[Hans Aberg]

Compile your grammar using the --verbose option, and look into the .output
file for the shift/reduce conflict rules. Then set token precedences for the
tokens closest to the "." in these conflicts. You probably have to set token
precdences for "[", "]", and all the tokens in your <E> (alt. <T>)
variables.
