我的项目（制作迷你 C 编译器）期间遇到问题。

没有错误，我可以扫描和解析迷你 C 源代码文件。

但是在 *.output 文件中我发现

State 17 conflicts: 2 shift/reduce

状态 154 冲突：1 班次/减少

在状态 17

4 DECLARATION: INT IDENTIFIER ';' . DECLARATION
6            | INT IDENTIFIER ';' .

INT    shift, and go to state 29
FLOAT  shift, and go to state 30

INT       [reduce using rule 6 (DECLARATION)]
FLOAT     [reduce using rule 6 (DECLARATION)]
$default  reduce using rule 6 (DECLARATION)

DECLARATION  go to state 31

这是我的 yacc 声明文件

DECLARATION : 
INT IDENTIFIER ';' DECLARATION %prec p10 {
    struct DECLARATION *decl = (struct DECLARATION *) malloc (sizeof (struct DECLARATION));
    decl->t = eInt;
    decl->id = $2;
    decl->prev = $4;
    $$ = decl;
}
|
FLOAT IDENTIFIER ';' DECLARATION {
    struct DECLARATION *decl = (struct DECLARATION *) malloc (sizeof (struct DECLARATION));
    decl->t = eFloat;
    decl->id = $2;
    decl->prev = $4;
    $$ = decl;
}
|
INT IDENTIFIER ';' {
    struct DECLARATION *decl = (struct DECLARATION *) malloc (sizeof (struct DECLARATION));
    decl->t = eInt;
    decl->id = $2;
    decl->prev = NULL;
    $$ = decl;
}
|
FLOAT IDENTIFIER ';' {
    struct DECLARATION *decl = (struct DECLARATION *) malloc (sizeof (struct DECLARATION));
    decl->t = eFloat;
    decl->id = $2;
    decl->prev = NULL;
    $$ = decl;
}
;
