Hi, all;
The following code is from
linux-2.4.20/include/asm-mips/mipsregs.h.
Could anyone tell how the difference between %z0 ("Jr")
and %0 ("r") is?
I compiled this code and deassemble the object, but I
can't find any
difference with my toolchains(gcc-2.95.3, binutils-2.11).
static inline void set_context(unsigned long val)
{
__asm__ __volatile__(
".set push\n\t"
".set reorder\n\t"
"mtc0 %z0, $4\n\t"
".set pop"
: : "Jr" (val));
}
Thanks in advance
mips4700
