Hi,
I'm learning ANTLR by modifying the C grammar and trying something interests
myself. The C grammar I started with is from:
http://www.antlr.org/grammar/1153358328744/C.g
Now I want to transform postfix_expression to its corresponding AST but
haven't known anything related to the transformation of the form xx
(aa|bb|cc)* yy
...
unary_expression
: postfix_expression
| unary_operator*^* unary_expression
;
postfix_expression
: primary_expression
( '[' expression ']'
| '(' ')'
| '(' argument_expression_list ')'
| '.' ID
)*
;
unary_operator
: '+'
| '-'
| '~'
| '!'
;
...
Can you help me with this?
Thanks,
Xiao Jia
