gcc - "Error: unsupported relocation against <register>" error with inline PPC assembly code in .c file -


i have below inline assembly code. when try compile it, throws error mentioned after code snippet.

unsigned int func(void) {   __asm__ ("mfspr r3, svr;"); }

below errors.

{standard input}: assembler messages: {standard input}:3349: error: unsupported relocation against r3 {standard input}:3349: error: unsupported relocation against svr {standard input}:3375: error: unsupported relocation against r3 {standard input}:3375: error: unsupported relocation against svr {standard input}:3510: error: unsupported relocation against r3 {standard input}:3510: error: unsupported relocation against svr {standard input}:3517: error: unsupported relocation against r3 {standard input}:3517: error: unsupported relocation against svr

can me fixing these?

apparently gas has no built-in support these registers. in order use should either define them or use indexes explicitly like:

mfspr 3, <some_index_here>

alternatively include: ppc_asm.tmpl.

if core e500 svr index 1023.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
