Example text

In a block of inline assembler code, the compiler should not optimize this block. Now that we have the basics of assembly and gcc inline assembly, we can turn our attention to some actual inline assembly code. Using what we just learned, we first explore a simple example and then a slightly more complex code block. Here's the first code example in which we pass variables to an inline block of code: ----------------------------------------------------------------------6 int foo(void) 7 { 8 int ee = 0x4000, ce = 0x8000, reg; 9 __asm__ __volatile__("movl %1, %%eax"; 10 "movl %2, %%ebx"; 11 "call setbits" ; 12 "movl %%eax, %0" 13 : "=r" (reg) // reg [param %0] is output 14 : "r" (ce), "r"(ee) // ce [param %1], ee [param %2] are inputs 15 : "%eax" , "%ebx" // %eax and % ebx got clobbered 16 ) 17 printf("reg=%x",reg); 18 } ----------------------------------------------------------------------- Line 6 This line is the beginning of the C routine.

This instruction takes the value in (GPR) register RS and stores it into the effective address formed by RA+D. The (GPR) register RA is then updated with this new effective address. • li RT, RS, SI (Load Immediate). This is an extended mnemonic for a fixed-point load instruction. It is equivalent to adding RT, RS, S1, where the sum of (GPR) RS and S1, the 16-bit 2s complement integer is stored in RT. If RS is (GPR) R0, the value SI is stored in RT. Note that the value being only 16 bit has to do with the fact that the opcode, registers, and value must all be encoded into a 32-bit instruction.

The simple constraints, such as "m" and "r," are used along with a PowerPC set of machine constraints. Here is a routine to exchange a 32-bit pointer. h 103 static __inline__ unsigned long 104 xchg_u32(volatile void *p, unsigned long val) 105 { 106 unsigned long prev; 107 108 __asm__ __volatile__ ("\n\ 109 1: lwarx %0,0,%2 \n" 110 111 " stwcx. %3,0,%2 \n\ 112 bne- 1b" 113 : "=&r" (prev), "=m" (*(volatile unsigned long *)p) 114 : "r" (p), "r" (val), "m" (*(volatile unsigned long *)p) 115 : "cc", "memory"); 116 117 return prev; 118 } ----------------------------------------------------------------------- Line 103 This subroutine is expanded in place; it will not be called.
