Hi, I have gone through the on-line docs for extended asm but i can't seem to find a relevant example for what i need to do. In one part of my application i need to set two registers from my C-code (r7 and r8) with two 32 bit values. It look quite like the below AFAIK, the lwi, lwz dont work in the inline assemble so i have use the below instead to get a 32bit value into the memory. I need code that does this: r7 = &buffer[0]; r8 = &buffer[max]; int tmp1 = 0x12345678; int tmp2 = (0x12345678 >> 16); asm volatile ( "li 7,%0;" "ori 7,7,%1;" : : "r"( tmp2 ) , "r"( tmp ) :"r7" ); ...but this dont work. When i look as the code from my debugger then i can see the following: All the above code has been translated into: lwz r0, (44)(r31) lwz r9, (40)(r31) li r7,0x0 ori r7,(09) This means that it diregards my input parameter (tmp2 and tmp1). Why is that? Since i see "lwz" in the assembler window then i really dont get why i can't used it within the asm "" directive. ------ Want more information?
