`/home/epuser/ajayku/final_test/qemu/qemu-1.6.0.ajay/tcg/tcg-op.h:27:1: error: expected` `identifier before ‘int’`

＆GT;并且＆＃34; tcg-op.h＆＃34;的初始内容文件

int gen_new_label(void);

static inline void tcg_gen_op0(TCGOpcode opc)

{
    *tcg_ctx.gen_opc_ptr++ = opc;
}

static inline void tcg_gen_op1_i32(TCGOpcode opc, TCGv_i32 arg1)
{
    *tcg_ctx.gen_opc_ptr++ = opc;
    *tcg_ctx.gen_opparam_ptr++ = GET_TCGV_I32(arg1);
}

代码＆＃34; tcg-op.h＆＃34;正在被＆＃34; tcg.h＆＃34;如下

typedef enum {
#define DEF(name, oargs, iargs, cargs, flags) INDEX_op_ ## name,
#include "tcg-op.h"
#undef DEF
 NB_OPS,
} TCGOpcode;

Answer 1

当在enum中包含“tcg-op.h”时，所需的“tcg-op.h”内容将复制到枚举中。

tcg-op.h中没有错误，但是当你在enum中包含它时，编译器会对int gen_new_label（void）感到震惊;在枚举中进行并抛出错误。

如果你这样做，它应该有效 -

#include "tcg-op.h"
#define DEF(name, oargs, iargs, cargs, flags) INDEX_op_ ## name,
typedef enum {
         DEF(ARG1, ARG2, ARG3, ARG4, ARG5)
         NB_OPS,
} TCGOpcode;
#undef DEF

typedef枚举相关的错误
