以下是我的 Bison 语法规则的相关部分：
statement:
expression ';' |
IF expression THEN statement ELSE statement END_IF ';'

expression:
IDENTIFIER |
IDENTIFIER '('expressions')' |

LIT_REAL |
BOOL_OP |
LOG_NOT expression |
expression operator expression |
'('expression')'
;
expressions:
expression |
expressions ',' expression
;
operator:
REL_OP |
ADD_OP |
MULT_OP |
LOG_OR |
LOG_AND
;
编译时，我得到 10 个 shift/reduce 冲突：
LOG_NOT表达式规则引起的5个冲突：
State 45
25 expression: LOG_NOT expression .
26 | expression . operator expression
REL_OP shift, and go to …
