The Tiger language is a small, imperative language with integer and string variables, arrays, records, and nested functions. Its syntax resembles some functional languages.

** Conflict (shift/reduce) in state 143.
** Token involved: TYPE
** This state is reached from main after reading:
LET ty_dec
** The derivations that appear below have the following common factor:
** (The question mark symbol (?) represents the spot where the derivations begin to differ.)
main
expr EOF
local
LET decs IN expr_seq END
list(dec)
(?)
** In state 143, looking ahead at TYPE, reducing production
** nonempty_list(loc(ty_dec)) -> ty_dec
** is permitted because of the following sub-derivation:
dec list(dec) // lookahead token appears because list(dec) can begin with TYPE
dec_ty_fun // lookahead token is inherited
nonempty_list(loc(ty_dec)) // lookahead token is inherited
ty_dec .
** In state 143, looking ahead at TYPE, shifting is permitted
** because of the following sub-derivation:
dec list(dec)
dec_ty_fun
nonempty_list(loc(ty_dec))
ty_dec nonempty_list(loc(ty_dec))
ty_dec
. TYPE symbol EQ ty
It's time to rewrite this compiler and finish the rest of chapters.
