[GSoC] TYPE stringfied in call to add_operator

[Prathamesh Kulkarni]

Hi,
    I have a daft question to ask. I was looking through genmatch, I
couldn't figure out why is tree code class (TYPE) stringified in call
to add_operator () ?

#define DEFTREECODE (SYM, STRING, TYPE, NARGS) \
    add_operator (SYM, #SYM, #TYPE, NARGS)

In add_operator()  tcc (argument corresponding to TYPE) is only used
to check if the tree code belongs to one of (tcc_unary, tcc_binary,
tcc_comparison, tcc_expression, tcc_reference) classes. Why can't we
use enum tree_code_class for tcc ?

Thanks and Regards,
Prathamesh
