运行时支持引导例程具有处理 C 自动初始化表的代码。以下 C 代码说明了如何在目标上处理自动初始化表。

typedef void (*handler_fptr)(const unsigned char *in, 
unsigned char *out);
#define HANDLER_TABLE  __TI_Handler_Table_Base
extern  unsigned int   HANDLER_TABLE;
extern  unsigned char *__TI_CINIT_Base;
extern  unsigned char *__TI_CINIT_Limit;
void auto_initialize()
{
   unsigned char **table_ptr;
   unsigned char **table_limit;
   /*--------------------------------------------------------------*/
   /* Check if Handler table has entries.                          */
   /*--------------------------------------------------------------*/
   if (&__TI_Handler_Table_Base >= &__TI_Handler_Table_Limit)
      return;
   /*---------------------------------------------------------------*/
   /* Get the Start and End of the CINIT Table.                     */
   /*---------------------------------------------------------------*/
   table_ptr   = (unsigned char **)&__TI_CINIT_Base;
   table_limit = (unsigned char **)&__TI_CINIT_Limit;
   while (table_ptr < table_limit)
   {
      /*-------------------------------------------------------------*/
      /* 1.Get the Load and Run address.                            */
      /* 2.Read the 8-bit index from the load address.              */
      /* 3.Get the handler function pointer using the index from    */
      /*    handler table.                                           */

      unsigned char *load_addr   = *table_ptr++;

                   (handler_fptr)(&HANDLER_TABLE)[handler_idx];
      /*-------------------------------------------------------------*/
      /* 4.Call the handler and pass the pointer to the load data   */
      /*    after index and the run address.                         */
