Following assembly statements were compiled with DIAB compiler. Does anyone knows eqivalent instructions in CW for ColdFire compiler.
/* save all of the registers we are going to modify */
__asm push es ;/* ES will contain a modified data segment */
__asm push di;/* DI is the offset of the data to sum */
__asm push dx;/* DX is the sum */
__asm push cx;/*CX is first used for temporary storage, and then to hold the loop control variable */
__asm les di, link16BitDataPtr;/* Load the pointer into ES:di */
 __asm mov cx, di;/* Save the offset portion of the pointer before we modify it */
__asm shr di, 4;/* Shift the offset right by 4 */
__asm push es;/* Copy the segment (es) into dx */
__asm pop dx;
__asm add dx, di;/* Add in the shifted offset */
__asm push dx;/* Copy the updated segment back into es */
__asm pop es;
__asm mov di, cx;/* Load the old offset, and mask off everything except the last 4 bits */
__asm and di, 000fh;
I am using CodeWarrior Development Studio for ColdFire Architectures Version 6.3, Build 14.
