gcc 3.3.1 can not compile current (2.4) arch/mips64/kernel/cpu-probe.c.
cpu-probe.c:118: warning: asm operand 0 probably doesn't match constraints
cpu-probe.c:118: warning: asm operand 1 probably doesn't match constraints
...
cpu-probe.c: In function `check_mult_sh':
cpu-probe.c:118: error: impossible constraint in `asm'
The code is:
static inline void align_mod(int align, int mod)
{
asm volatile(
".set push\n\t"
".set noreorder\n\t"
".balign %0\n\t"
".rept %1\n\t"
"nop\n\t"
".endr\n\t"
".set pop"
:
: "i" (align), "i" (mod));
}
The align_mod() and mult_sh_align_mod() should be written as macro?
